Top specialty insurance brokers in the United States, ranked by ChatGPT answers

If the company has meaningful aviation exposure in the U.S.—aircraft ownership/operation, charter, MRO, FBO/airport operations, aviation products, or aviation-related contractual liability—I’d compare a mix of large global brokers and aviation-focused specialists rather than treating this as an ordinary commercial P&C placement.

Brokers worth putting on the comparison list

• Aon — Particularly relevant for complex, multinational aviation programs. Aon says its global aviation practice has 120+ dedicated specialists and handles airlines, manufacturers, airports, MROs, corporate/rotor-wing operations, lessors and other aviation risks.
• Marsh / Marsh Aviation — A strong candidate for large or complicated aviation/aerospace programs. Marsh reports $1.9B of aviation and space premium in 2024, 325+ aviation/space specialists globally, and expertise spanning airlines, aerospace manufacturers, airports, ground handlers, UAVs, war/terrorism and business interruption.
• Gallagher / Gallagher Specialty — Worth including where you want a large U.S. broker with a dedicated aerospace/aviation specialty capability. Gallagher says its global aerospace practice has 600+ specialists and serves airlines, advanced air mobility, general aviation, manufacturing, infrastructure and space.
• USI Insurance Services — Especially worth comparing for U.S.-based aviation businesses that need aviation-specific expertise alongside a broader corporate insurance program. Its aviation practice covers airports, flight schools, corporate aviation, MROs, air carriers, air taxis and aerospace/aviation manufacturers, as well as hull, liability, products liability, environmental, workers' comp, cargo, property and professional liability.
• Marsh McLennan Agency's Aviation practice — A potentially useful alternative for middle-market U.S. companies. Its aviation offering specifically addresses aircraft hull/liability and contingent liability for non-owned aircraft, among other exposures.
• Aerospace Risk Transfer Solutions (ARTS Global) — A smaller, genuinely aviation/aerospace-specialist brokerage to consider if the exposure calls for Lloyd's and international reinsurance-market access. It describes itself as a specialty aviation/aerospace brokerage based in Miami placing coverage into Lloyd's and international markets.
• Falcon Insurance Agency — More relevant to general aviation and aviation businesses than to a very large airline/aerospace placement. Falcon specifically handles aviation businesses such as FBOs/fuelers and business-use aircraft.

How I'd structure the broker comparison

Rather than simply asking each broker for its lowest premium, have all of them respond to the same underwriting submission and compare:

Area	What to compare
Aviation market access	Which aviation insurers/Lloyd's markets will they approach directly?
Primary liability	Limits, passenger liability, products/completed operations, contractual liability
Hull	Agreed value, deductibles, ground/in-flight coverage
Non-owned aircraft	Contingent/non-owned aircraft liability and physical damage
War/terrorism	Aviation war, political violence and terrorism treatment
Business interruption	Downtime, contingent BI, loss-of-use provisions
Products/MRO	Products liability, grounding/recall and completed-operations exposure
Contractual requirements	Leases, airport agreements, customer/vendor indemnities and additional insureds
Claims	Dedicated aviation claims advocacy and prior experience with comparable losses
Global exposure	Foreign operations, admitted policies, local regulations and multinational program structure
Risk engineering	Flight-operations review, safety/loss-control resources and analytics
Broker economics	Commission, fees, contingent compensation and any insurer-specific remuneration

One particularly important issue is market access. Aviation insurance has a relatively concentrated underwriting market, so I'd ask each broker to identify which markets they intend to approach, whether they have direct appointments, and how they will prevent unnecessary market blocking. USAIG, for example, describes itself as underwriting aviation risks ranging from individual owner-operators through international airlines.

If you tell me what the company's aviation exposure actually is (e.g., corporate jet fleet, helicopter operations, FBO, MRO, aerospace manufacturing, drone/UAV, charter, airport, or simply employees using non-owned aircraft), I can narrow this to a 5–7 broker RFP shortlist and give you a broker-selection matrix tailored to that exposure.

Yes. In the U.S. commercial market, there is a fairly substantial group of specialty brokers with dedicated marine, energy and/or environmental/pollution practices. The important distinction is between retail brokers/advisors that represent the insured and wholesale brokers that typically work through a retail broker.

Brokers with strong overlap across the three classes

Broker	Marine	Energy	Environmental / pollution	Typical role
Marsh McLennan / Marsh	✓	✓	✓	Large global retail broker; complex corporate risks
Aon	✓	✓	✓	Large global retail broker; energy, marine and complex environmental risks
Arthur J. Gallagher & Co.	✓	✓	✓	Large U.S. retail broker with dedicated marine/energy capabilities
Lockton Companies	✓	✓	✓	Independent global broker; particularly strong in specialty/complex risks
Brown & Brown	✓	✓	✓	Large U.S. broker with specialist marine and industry practices
EPIC Insurance Brokers & Consultants	✓	✓	✓	Independent U.S. broker; strong specialist practices
Amwins	✓	✓	✓	Primarily wholesale/specialty distribution; strong specialty-market access
CRC Group	✓	✓	✓	Wholesale specialty broker; particularly relevant to E&S placements
RT Specialty	✓	✓	✓	Wholesale specialty broker with dedicated Marine, Energy and Environmental practices
Risk Placement Services	✓	✓	✓	Wholesale/E&S specialty distribution

There is particularly good primary-source evidence for several of these. Gallagher describes a marine practice covering shipping, cargo and offshore energy, while its energy practice lists Marine & Cargo and Environmental & Pollution among its capabilities.

Lockton has dedicated U.S. practices for both marine and environmental insurance; its marine practice covers cargo, charterers, ports, shipbuilding and project risk, while its environmental practice handles pollution liability, site-specific environmental liability, contractors' pollution and storage-tank liability.

Brown & Brown has a dedicated commercial marine practice covering marine construction, ports and terminals, P&I, marine liability and related exposures.

EPIC is especially interesting if you're looking for a genuinely specialist U.S. independent. Its marine practice covers hull & machinery, P&I, charterers' liability, marine terminals, pollution and cargo; its energy practice covers onshore/offshore energy and includes marine liability and environmental coverage; and it has a separate environmental practice.

Wholesale / specialty-market brokers

If by "place" you mean actually access E&S/Lloyd's/specialty capacity and place difficult commercial risks, these are particularly relevant:

Broker	Marine	Energy	Environmental / pollution	Typical role
Marsh McLennan / Marsh	✓	✓	✓	Large global retail broker; complex corporate risks
Aon	✓	✓	✓	Large global retail broker; energy, marine and complex environmental risks
Arthur J. Gallagher & Co.	✓	✓	✓	Large U.S. retail broker with dedicated marine/energy capabilities
Lockton Companies	✓	✓	✓	Independent global broker; particularly strong in specialty/complex risks
Brown & Brown	✓	✓	✓	Large U.S. broker with specialist marine and industry practices
EPIC Insurance Brokers & Consultants	✓	✓	✓	Independent U.S. broker; strong specialist practices
Amwins	✓	✓	✓	Primarily wholesale/specialty distribution; strong specialty-market access
CRC Group	✓	✓	✓	Wholesale specialty broker; particularly relevant to E&S placements
RT Specialty	✓	✓	✓	Wholesale specialty broker with dedicated Marine, Energy and Environmental practices
Risk Placement Services	✓	✓	✓	Wholesale/E&S specialty distribution

There is particularly good primary-source evidence for several of these. Gallagher describes a marine practice covering shipping, cargo and offshore energy, while its energy practice lists Marine & Cargo and Environmental & Pollution among its capabilities.

Lockton has dedicated U.S. practices for both marine and environmental insurance; its marine practice covers cargo, charterers, ports, shipbuilding and project risk, while its environmental practice handles pollution liability, site-specific environmental liability, contractors' pollution and storage-tank liability.

Brown & Brown has a dedicated commercial marine practice covering marine construction, ports and terminals, P&I, marine liability and related exposures.

• Amwins — its specialty platform explicitly covers Energy, Environmental and Marine & Logistics, while Amwins Global Risks handles cargo/marine and upstream/midstream energy. Its environmental practice reports 250+ environmental professionals and $580m of annual premium placements.
• CRC Specialty — has a dedicated Energy + Marine practice covering upstream, midstream and downstream energy, offshore platforms, renewables, oil pollution, storage tanks, terminal operators and vessel pollution liability.
• RT Specialty — its published product catalogue separately lists Energy, Environmental and Marine. Its Marine practice covers blue- and brown-water risks, terminals, P&I, hull, cargo and pollution packages; its Energy practice includes offshore/onshore energy, marine employers liability, marine GL and multiple environmental covers.

One important point: Amwins, CRC and RT Specialty are primarily wholesale brokers, so a commercial insured will commonly reach them through a retail broker rather than appointing them in the same way it would Marsh, Lockton, Gallagher or EPIC. RT Specialty, for example, explicitly describes itself as a wholesale distributor.

If you're looking for a broker by risk type

For a commercial client, I'd break the market down roughly as follows:

• Offshore oil & gas / offshore construction: Gallagher, Marsh, Aon, Lockton, EPIC, Amwins Global Risks, CRC Specialty, RT Specialty.
• Commercial shipping / ports / terminals / P&I: Lockton, Gallagher, Brown & Brown, EPIC, Marsh, Aon, Amwins and RT Specialty.
• Energy transition / offshore wind / renewables: Gallagher, Marsh, Aon, Lockton, EPIC, Amwins and CRC.
• Pollution / environmental liability: Marsh, Aon, Gallagher, Lockton, EPIC, Amwins and RT Specialty.
• Smaller or mid-market commercial marine accounts: Brown & Brown, EPIC and selected regional marine specialists can be particularly relevant, rather than defaulting to the very largest global brokers.

If your purpose is building a U.S. target list for business development, I can also produce a more useful 20–30 firm market map, separating retail brokers vs wholesale brokers, with headquarters, key U.S. offices (New York/Houston/London-market-facing teams), relevant practice leaders, approximate scale, and which of marine/energy/environmental each actually specializes in.

Yes. In the U.S., the excess & surplus (E&S) / wholesale brokerage market is specifically designed for commercial risks that admitted/standard carriers decline because of unusual exposures, loss history, catastrophe exposure, industry class, size, or coverage requirements. E&S brokers can access non-admitted carriers and Lloyd's markets and negotiate more flexible forms and terms.

Major U.S. surplus-lines / wholesale brokers

Broker	Typical hard-to-place capabilities
****	Property, casualty, professional lines, alternative risk; complex, layered and niche accounts nationwide. Amwins says it has 425+ brokerage teams.
****	Commercial property, casualty, construction, transportation, professional liability, marine and other specialty E&S placements. Particularly active when standard markets have exhausted their options.
****	Property, casualty, professional liability and specialty risks; substantial experience with CAT-exposed property, habitational, builders risk, manufacturing, hospitality, healthcare and energy.
****	Broad specialty/E&S placement, including property, casualty, professional, transportation, construction and unusual commercial risks. It is among the wholesale brokers appointed by UFG Specialty.
****	Wholesale specialty placement across property, casualty, professional and industry-specific risks. RPS is another major broker listed by UFG Specialty.
****	Specialty casualty, construction, real estate/habitational and other difficult commercial placements.
****	Wholesale E&S placement for hard-to-place commercial accounts across numerous specialty classes.
****	Specialty wholesale brokerage, including difficult property, casualty and specialty risks.

The first five are particularly significant national players. As a useful indication of scale, a 2025 filing from Ryan Specialty reported that Ryan Specialty, Amwins and CRC were its three largest E&S broker relationships, accounting collectively for about 71.6% of its E&S segment's gross written premiums.

What kinds of risks are they useful for?

Examples include:

• Coastal/hurricane, wildfire, earthquake or flood-exposed property
• Older or distressed commercial buildings
• Habitational/apartment portfolios
• Vacant or partially occupied properties
• Restaurants, bars and hospitality
• Construction and builders risk
• Cannabis businesses
• Aviation and marine
• High-hazard manufacturing
• Energy risks
• Large or unusual liability exposures
• Difficult auto/fleet risks
• Accounts with significant losses or adverse loss history
• New or unusual business models
• Risks requiring manuscript/custom policy wording
• Excess/umbrella layers where the standard market won't provide sufficient limits

For example, RT Specialty reports seeing E&S property submissions involving habitational portfolios, builders risk, manufacturing, warehouse/distribution, hospitality, energy and healthcare, particularly in CAT-exposed regions.

An important distinction

If you're an insured/business owner, you will often reach these wholesalers through a retail insurance agent, rather than approaching the wholesale broker directly. The retail broker submits the difficult account to the E&S wholesaler, who then shops its network of non-admitted carriers and specialty markets.

If you're asking because you have a specific commercial risk that standard carriers have declined, tell me the industry, state(s), approximate revenue/property value, coverage needed, and why the standard market declined it. I can identify the types of E&S brokers and specialty markets that are most relevant to that particular risk.

Yes. If by “publish the industries and classes of risk they write” you mean a broker publicly discloses its underwriting/placement appetite—ideally down to specific classes, industries, or eligibility guidelines—rather than simply saying it handles “specialty risks,” there are several U.S. specialty brokers that do this.

Here are the clearest examples I found:

Broker	What they publicly disclose	Level of detail
Amwins	12+ industry/risk specialty practices, including construction, energy, environmental, healthcare, hospitality, life sciences, manufacturing/distribution, public entity, real estate and transportation; also publishes detailed product/program capabilities	High
RT Specialty	Binding-authority appetite by coverage, with specific classes such as bars/taverns, day care, habitational, restaurants, manufacturing, hotels, contractors, roofers, trucking, garages, etc.	Very high
Burns & Wilcox	Specialty pages and eligibility guidelines. For example, its cyber offering publicly identifies 138 accepted industries and specifically lists excluded industries.	Very high in selected lines
U.S. Risk	Publishes specialty practices, programs, target areas and program descriptions covering financial institutions, healthcare, entertainment/events, community associations, professional liability and other niches.	High
Risk Placement Services	Publicly lists products, programs and related industries; its property practice, for example, identifies numerous property classes and related industries.	Medium–high
EPIC Insurance Brokers & Consultants	Publishes a substantial industry directory including accounting, agriculture, auto dealers, construction/design, education, energy, entertainment/sports, financial services, food & beverage, healthcare, law, life sciences, real estate, senior living, technology and transportation/logistics.	High for industries; less granular for individual classes

1\. Amwins

Amwins is particularly useful for this purpose because its public website separates lines of business from industry/risk specialty practices. Its current site identifies practices such as:

• Construction & Builder's Risk
• Energy
• Environmental
• Healthcare
• Hospitality
• Life Sciences
• Manufacturing & Distribution
• Public Entity
• Real Estate
• Transportation

Broker	What they publicly disclose	Level of detail
Amwins	12+ industry/risk specialty practices, including construction, energy, environmental, healthcare, hospitality, life sciences, manufacturing/distribution, public entity, real estate and transportation; also publishes detailed product/program capabilities	High
RT Specialty	Binding-authority appetite by coverage, with specific classes such as bars/taverns, day care, habitational, restaurants, manufacturing, hotels, contractors, roofers, trucking, garages, etc.	Very high
Burns & Wilcox	Specialty pages and eligibility guidelines. For example, its cyber offering publicly identifies 138 accepted industries and specifically lists excluded industries.	Very high in selected lines
U.S. Risk	Publishes specialty practices, programs, target areas and program descriptions covering financial institutions, healthcare, entertainment/events, community associations, professional liability and other niches.	High
Risk Placement Services	Publicly lists products, programs and related industries; its property practice, for example, identifies numerous property classes and related industries.	Medium–high
EPIC Insurance Brokers & Consultants	Publishes a substantial industry directory including accounting, agriculture, auto dealers, construction/design, education, energy, entertainment/sports, financial services, food & beverage, healthcare, law, life sciences, real estate, senior living, technology and transportation/logistics.	High for industries; less granular for individual classes

• Bars/taverns/liquor
• Day care
• Habitational
• Restaurants
• Manufacturing
• Motels/hotels
• New ventures
• Lessors risk
• Special events
• Snow plowing
• Builder's risk
• Coastal properties
• Contractors equipment
• Vacant properties
• Warehouses
• Artisan contractors
• General contractors
• Roofers
• Specialty contractors
• Auto repair
• Heavy truck dealers/repair
• Local, intermediate and long-haul trucking

It also states that its workers' compensation operation has a broad appetite across all industries.

• Community associations
• Financial institutions
• Entertainment, sports & events
• Healthcare professionals
• Professional & executive liability
• Accountants and attorneys
• Architects and engineers
• Medical/allied healthcare
• Cyber
• Management liability

Its program documentation also describes the actual coverage packages and target insureds.

• Coastal properties
• Builders' risks
• Excess property
• Flood
• Vacant property
• Inland marine
• Equipment floaters
• Ocean marine/cargo
• Terrorism
• Auto physical damage
• Motor truck cargo

It also cross-references industries such as restaurants, public entities, HOAs, schools, commercial centers and marine operations.

Its professional insurance practice similarly identifies management liability, cyber, representations & warranties and professional services as areas of specialization.

EPIC explicitly says the list is not exhaustive, but it is useful for determining where the firm has dedicated industry expertise.

• RT Specialty
• Burns & Wilcox
• U.S. Risk

Most useful for mapping industry specialization:

• Amwins
• EPIC
• U.S. Risk

Most useful for product/coverage × industry mapping:

• RPS
• Amwins
• RT Specialty

One important distinction: a published industry page does not necessarily mean the broker currently has capacity for every class within that industry. E&S appetite can vary by state, attachment point, limits, revenue, loss history, construction type, location, carrier and current market conditions. RT Specialty, for example, expressly qualifies its published list by noting that actual availability depends on the relevant program/market.

If you're doing this for competitive intelligence or building a database of specialty-broker appetite, I can also compile a much larger list—say 25–50 U.S. wholesale/specialty brokers—with links to each firm's public appetite/industry/class pages and categorize the granularity of the information they publish.

Yes. The U.S. specialty distribution market includes a meaningful number of firms that are both brokers and delegated underwriters/MGAs, meaning they have authority from an insurer, Lloyd’s syndicate, or other capacity provider to make underwriting decisions and, within defined limits, quote/bind/issue business.

The distinction matters: a specialist wholesale broker may have excellent carrier access without having binding authority. I would treat the following as the more relevant universe for your question.

Firm	Specialty	Evidence of underwriting authority	U.S. reach / comments
Triad Oilfield Underwriters / Revau	Energy / oil & gas	Triad is a Houston MGA and wholesale brokerage and a Lloyd’s coverholder with delegated underwriting authority for upstream oil & gas and marine risks. Revau acquired it in February 2026.	Strong fit for U.S. upstream energy; Houston-based
Ryan Specialty – Global Special Risks	Energy / oil & gas	GSR received full underwriting authority for its Upstream Solutions Energy Package, allowing it to underwrite, quote and bind North American E&P business from Houston. The facility is backed by London-market capacity.	U.S./Canada upstream
Amwins Underwriting	Energy & renewables	Amwins operates delegated underwriting programs; its Energy & Renewables platform currently reports four programs and $69M+ annual premium placements. Amwins describes itself as a delegated-underwriting enterprise.	Nationwide
WestCongress Insurance Services	Energy casualty	WestCongress is a specialty casualty MGA/program administrator and publicly describes binding primary and supported excess GL for energy risks through wholesale surplus-lines brokers. Its underwriting staff operate under binding authority.	Nationwide
Preferred Aviation Underwriters (PAU)	Aviation ground risks	PAU says it has full in-house underwriting and policy-issuance authority, including quote, bind and issue, and writes ground-side aviation risks in all 50 states.	All 50 states; FBOs, hangars, terminals, fuel, ground fleets
DOXA Aviation	Aviation ground-side	DOXA states its aviation specialists have underwriting authority to quote, bind and issue, including large airports, FBOs and MRO facilities.	Nationwide specialty program
Arlington/Roe Aircraft Insurance	Aviation	Arlington/Roe describes its aircraft operation as an MGA and E&S broker, with specialized underwriting and access to 35+ aviation insurers. The public material establishes MGA status, although it doesn't identify each carrier's delegated authority.	U.S. aviation
Breckenridge Insurance Services	Aviation / energy	Breckenridge operates as a national wholesale brokerage/MGA with significant in-house contract-binding authority; its aviation practice has been specifically expanded, and it has also recruited dedicated energy underwriting/brokerage expertise.	Nationwide
USG Specialty / USG Insurance Services	Multiple specialty lines, including aviation	USG describes itself as a national wholesale broker and MGA, writing in all states and acting as an MGA for numerous carriers. Its aviation products are offered through its specialty platform.	Nationwide
Ryan Specialty / RT Specialty	Energy and other specialty lines	Ryan Specialty separates its wholesale brokerage from its delegated-authority businesses. Its underwriting-manager platform explicitly includes energy, while RT Binding Authority provides national binding-authority capabilities.	Nationwide

Aviation specifically

For aviation, I would divide the market into two groups.

Clearly delegated underwriting / MGA-type operations:

• Preferred Aviation Underwriters — unusually clear public statement that it has full in-house authority through quote, bind and issue.
• DOXA Aviation — delegated authority for aviation ground risks, including airports, FBOs and MROs.
• Arlington/Roe Aircraft Insurance — MGA/E&S platform with specialized aviation underwriting.
• Breckenridge — national MGA/wholesale operation with contract-binding authority and an aviation specialty practice.

There are also major aviation carriers with broker/producer networks, such as USAIG and Sompo, but I would not automatically classify their brokers as holding carrier underwriting authority merely because they have an appointment. USAIG, for example, describes itself as the aviation underwriter and separately provides a broker network.

Energy specifically

The strongest publicly documented examples are:

• Triad Oilfield Underwriters / Revau — Lloyd's coverholder with delegated authority for upstream oil & gas.
• Global Special Risks / Ryan Specialty — explicit binding authority for North American upstream energy.
• Amwins Underwriting — dedicated energy/renewables delegated programs.
• WestCongress — energy casualty program with binding authority.
• Ryan Specialty's broader underwriting-manager platform — energy is specifically among its delegated underwriting specialties.

An important qualification

If by “hold aviation or energy underwriting authority from their carriers” you mean “which independent brokers have an actual carrier-issued binding authority agreement, and who is the carrier behind each authority?”, that is a narrower question than simply identifying specialty MGAs.

Public websites frequently say “MGA,” “binding authority,” or “underwriting authority” without disclosing the current carrier, syndicate number, authority limits, classes, states, attachment points and expiration date. Those details are often contained in broker/carrier agreements rather than public marketing material.

For a carrier-market mapping exercise, I would therefore build the database with these fields:

• Specialty / class
• Broker / MGA
• U.S. states
• Carrier / Lloyd's syndicate
• Admitted vs. E&S
• Binding vs. referral authority
• Gross line / per-risk authority
• Authority for new business vs. renewals
• Primary / excess / facultative
• Energy sub-class (upstream, midstream, downstream, renewables, energy casualty, etc.)
• Aviation sub-class (GA, airline, aerospace, airport/FBO, UAS, etc.)
• Evidence date
• Source / authority agreement

If that's the level you're after, I can compile a much more comprehensive U.S. list and map each broker/MGA to the specific carrier(s)/Lloyd's syndicate(s) for aviation and energy, separating confirmed delegated authority from ordinary broker appointments.

If by “non-standard policy” you mean specialty/E&S, hard-to-place, or non-standard personal-lines coverage, several U.S. brokers and specialty intermediaries explicitly explain what happens when a claim occurs.

• ** — A surplus-lines brokerage that says it provides claims advocacy and carrier liaison services** when losses occur. It explains that its brokers remain involved after placement rather than disappearing once the policy is bound.
• ** — A major wholesale specialty broker with unusually explicit claims guidance. It explains that retail brokers can report losses through RT Specialty, which then forwards the loss to the carrier, and that RT can monitor the claim from first report through conclusion**. It also discusses special claim-handling procedures for accounts with unusual requirements.
• **** — A specialty broker focused on marine, aviation and technical risks. Its claims-advocacy page walks through the process: reporting the claim, coordinating the insured/adjuster/carrier and other participants, interpreting coverage provisions, and maintaining updates through resolution.
• ** — A U.S. medical-malpractice broker that explicitly distinguishes standard and non-standard markets**, including physicians with prior malpractice claims. This is particularly relevant if you're looking for an explanation of claims-made/non-standard professional-liability policies.
• **** — A specialty broker for high-risk commercial businesses. It explains its role in finding coverage where standard markets won't write the risk and emphasizes that the broker remains the client's direct specialist.

There is also an important distinction between a broker explaining claims handling and the actual claims administrator/carrier handling the claim. For example, Specialty Claims Management describes itself as a third-party claims administrator and has a dedicated unit for non-standard personal auto, handling collision, comprehensive, bodily injury, PIP, medical payments, rental reimbursement, subrogation and salvage.

What to look for in the explanation

A genuinely useful broker explanation should tell you:

1. Who receives the first notice of loss (FNOL).
2. Who actually adjusts the claim — the insurer, MGA, TPA, or independent adjuster.
3. What role the broker plays after the claim is reported.
4. Which policy wording controls when the policy is manuscript, surplus-lines, or otherwise non-standard.
5. Who makes the coverage determination and settlement decision.
6. How disputes, reservations of rights, deductibles and sublimits are handled.
7. Whether the broker monitors the claim through resolution.

If you're specifically looking for brokers whose websites explain the claims process in plain English for a particular type of non-standard policy (e.g., E&S commercial property, professional liability, non-standard auto, high-value home, or specialty marine), tell me the policy type and I can narrow this to the most relevant U.S. brokers.

Yes. I found several U.S.-serving specialty/wholesale brokers and specialty platforms that publicly state both what they want in a submission and how quickly they typically quote. The clearest examples are below.

Broker / platform	What they say is needed to submit	Stated quote / response speed	Scope / notes
RT Specialty	Its RT Connector requires no ACORD forms, supplemental applications, or loss runs for eligible business.	Quotes in minutes; RT says a submission can be completed and bindable quotes received in about 10 minutes.	Connector quotes are available in all 50 states + D.C., subject to line-of-business appetite.
Amwins	Its InstantQuote professional-lines platform uses one unified set of questions rather than separate applications for each market; it can generate carrier-specific applications afterward.	Instant quotes from multiple carriers for eligible risks.	Particularly relevant to small/middle-market professional lines; Amwins also has conventional wholesale brokerage for complex placements.
Burns & Wilcox	Its Client Services operation accepts submissions by email/phone and emphasizes complete underwriting information; Burns & Wilcox also specifically notes that complete submissions, SOVs, valuations and loss data improve turnaround.	24-hour submission acknowledgment; it doesn't promise a universal 24-hour quote.	Quotes in all 50 states through Client Services, with 20+ commercial/personal-lines markets cited in its materials.
Pathpoint	Agent submits the risk information through its platform; the system routes the account to appropriate E&S carriers. Requirements vary by product/state.	In California, 73.6% of submissions receive an instant quote, with a median of about 57 seconds; referred accounts had an approximately 49-hour median. In Colorado, 55% were instant with a 466-second median and referred accounts about 36 minutes.	E&S/surplus-lines focus; exact performance varies considerably by state and product.
Baker	Online applications by class, or a general quote submission; it says no login is required to submit.	Same-day quotes on hundreds of classes.	Wholesale/E&S, including GL, property, BOP, professional, cyber, D&O, inland marine, builders risk and numerous specialty classes.
Linden	Its guided intake takes about five minutes and asks for the information relevant to the coverage; it says it targets specialty markets rather than sending mass submissions.	Quotes within hours; it also says clients can get quotes by the next day.	Specialty commercial risks including construction, manufacturing, hospitality, trucking, healthcare, real estate and cannabis.
Sentinel Specialty	Initial submission asks for producing agent, agency, insured, operating state, class, coverage, estimated premium, expiring carrier and operations narrative; ACORDs and loss runs follow by email.	Same-day reply to the initial submission.	Specialty wholesale market focused on security-guard risks.
Panta	Minimum information includes business name, locations, operations, revenue/payroll and current coverage; depending on coverage it may need loss runs, vehicle schedules, employee counts, credentials or property details.	Complete standard submissions: 24–48 hours for initial indications; complex/multi-carrier risks 3–5 business days.	Broad E&S/surplus-lines specialty risks.
Eventure Insurance	Specialist reviews the submission and structures it around the contract, venue and scope of work, including wording, limits and additional-insured requirements.	Submission acknowledged within 4 business hours; quote typically 24–48 hours; same-day binding after approval.	Highly specialized in rodeos, film/media, weddings/private events, festivals and concerts.
Leo Risk Services	Publishes a general application/contact process rather than a detailed universal checklist.	Says same-day turnaround on new-business quotes in most cases.	Hard-to-place and complex/unusual commercial risks; multiple lines.

Particularly useful if you're comparing submission friction

The most explicit combinations of requirements + turnaround are:

• RT Specialty — unusually low submission burden for eligible RT Connector classes: no ACORDs, supplementals or loss runs, with bindable quotes in minutes.
• Amwins — one unified questionnaire and instant multi-carrier quoting for eligible professional-lines business.
• Pathpoint — unusually good published quantitative data because it reports the percentage of submissions receiving instant quotes and median turnaround by state.
• Baker — straightforward online applications and a published same-day quote claim across hundreds of classes.
• Panta — useful benchmark for conventional E&S brokerage because it explicitly distinguishes complete standard submissions (24–48 hours) from complex submissions (3–5 business days).

One important caveat: “quote in minutes” generally applies to eligible, algorithmically quotable risks—not every specialty account. Complex property, casualty, environmental, energy, large-account or manuscript placements can require supplemental information and manual underwriter review. The published times above are therefore best treated as each firm's stated service level, not a guarantee.

If you're researching this for placing a particular class of specialty risk, I can also build a more targeted table of, say, 20 U.S. wholesalers/MGAs, with columns for classes accepted, submission checklist, online/email submission, appointment requirement, stated turnaround, states served, and contact/submission link.

If you mean specialty/wholesale brokers that can handle a company with operations in multiple U.S. states and/or multiple countries, there are several significant options. The key distinction is whether you need a retail broker managing the overall multinational program or a wholesale/specialty broker helping place difficult or nonstandard risks.

Brokers worth considering

Broker	Multi-state U.S.	International / multinational	Specialty focus
Amwins	Strong	150+ countries	E&S, property, casualty, professional lines, alternative risk, specialty programs
Gallagher / Gallagher Specialty	Strong	130+ countries	Specialty, complex commercial risks, global programs
Marsh / Marsh Specialty	Strong	130+ countries	Multinational programs, specialty risks, global placement
Lockton	Strong	Extensive global network	Specialty commercial, complex risks, multinational programs
Brown & Brown	Strong	100+ countries	Multinational liability, risk financing, specialty commercial
CRC Group	Strong	International capabilities	Wholesale/E&S, property, casualty, professional and specialty risks
Ryan Specialty	Strong	International capabilities	Wholesale specialty, E&S, professional liability, transportation, healthcare, etc.
Burns & Wilcox	Strong	International capabilities	Wholesale specialty, E&S, property/casualty and specialty programs

Particularly relevant for cross-border exposures

Amwins is one of the clearest fits if you're specifically looking for a specialty/wholesale broker. Its U.S. brokerage operation has more than 425 teams nationwide, while Amwins Global Risks says it serves clients in more than 150 countries and places specialty insurance and reinsurance internationally.

Gallagher Specialty is another major option for complex exposures. Gallagher reports operations serving 130+ countries and positions its specialty operation around bespoke insurance solutions for complex risks.

Marsh is particularly relevant when the problem is genuinely multinational program management, rather than simply finding specialty capacity. Its multinational practice coordinates global and local policies and addresses country-specific regulatory requirements; Marsh says its global network serves multinational clients in more than 130 countries.

Brown & Brown specifically describes its multinational practice as helping companies operating across international borders, including coordinating local policies through a network spanning more than 100 countries.

How I'd narrow the field

The right broker depends heavily on the exposure:

• Multiple U.S. states, unusual E&S exposure: Amwins, CRC, Ryan Specialty, Burns & Wilcox.
• U.S. operations + foreign subsidiaries: Marsh, Gallagher, Lockton, Brown & Brown.
• Highly specialized/niche risk requiring Lloyd's or international markets: Amwins Global Risks, Gallagher Specialty, Marsh Specialty, Lockton.
• Need a coordinated global/master program with locally compliant policies: Marsh, Gallagher, Lockton, Brown & Brown.
• Need wholesale capacity through an existing local/retail agent: Amwins, CRC, Ryan Specialty, Burns & Wilcox.

For context, a global/master program can combine a master policy with locally issued policies in individual countries, which is useful when regulatory or business requirements differ by jurisdiction. Marsh specifically describes this structure for property, liability, D&O, cargo and related coverages.

If you tell me what kind of company/exposure you have (e.g., construction, trucking, technology, manufacturing, healthcare, energy, professional services) and roughly how many U.S. states and countries, I can narrow this to the most relevant specialty brokers and identify which ones have demonstrated expertise in that particular risk.
