W. R. Berkley Corporation
W. R. Berkley became one of America’s largest commercial insurers by building roughly 60 specialist businesses and letting them stay close to the risk. The center supplies capital; the edges supply judgment.
Marsh
The 155-year-old professional services firm has turned uncertainty into a $27 billion business. Its real product is neither a policy nor a spreadsheet, but a better-informed decision before the bill comes due.
UFG Insurance
For 80 years, the Cedar Rapids carrier behind the interlocking-U logo has insured contractors, shopkeepers and factories the unglamorous way - one independent agent at a time.
The Baldwin Group
The Tampa firm grew from a Florida brokerage into a $1.5 billion national platform. Its next act is less about selling policies than connecting advice, underwriting, embedded distribution and AI into one insurance operating system.
Chubb
Chubb can insure a Vermeer, a vineyard, a ransomware attack and the cargo crossing an ocean. Its real product is disciplined judgment - sold through brokers, agents and digital partners across 54 countries and territories.
Slide
Slide became one of Florida's largest home insurers by doing the unfashionable work of pricing hurricane risk - then pairing old-school agents with a very modern data engine.
Authentic
Authentic is a New York insurtech building the infrastructure that lets software companies, franchisors, and associations launch their own insurance programs - so-called captives - for the small businesses they already serve. Its 'Captive in a Box' platform handles the parts that normally take years and a team of specialists: underwriting, rate filings, actuarial work, reinsurance, capitalization, regulatory compliance, and claims. Partners such as Mindbody, Restaurant365, PushPress, and theCut can embed tailored coverage for gyms, salons, restaurants, and other Main Street businesses through a single integration, while member businesses can share in the savings when claims run low.
FurtherAI
FurtherAI builds domain-specific AI 'teammates' for the insurance industry, automating the busywork of underwriting, claims, submissions, policy comparison and compliance. Founded in 2023 by Aman Gour and Sashank Gondala and launched out of Y Combinator's Winter 2024 batch, the San Francisco company parses messy insurance documents - broker letters, property schedules, ACORD forms, loss runs - and turns them into structured, actionable data so professionals can focus on judgment instead of re-keying. It raised a $25M Series A led by Andreessen Horowitz in October 2025, roughly six months after a $5M seed, and supports customers writing over $15 billion in premiums across all 50 states.
Re
Re is a blockchain-powered reinsurance protocol - often described as a decentralized Lloyd's of London - that connects alternative capital to regulated insurance risk. Built originally on Avalanche, Re lets stablecoin depositors back baskets of real reinsurance treaties and earn premium-driven yield, while the on-chain design brings transparency and auditability to a historically opaque, intermediary-heavy market. Founded in 2022 by former Cover CEO Karn Saroya, Re has grown to roughly half a billion dollars in total value locked and launched its $RE governance token in June 2026.
ResiQuant
ResiQuant is a San Francisco insurtech that fuses structural-engineering expertise with AI to help property insurance carriers and MGAs underwrite catastrophe-exposed buildings with engineering-grade confidence and no backlog. Founded in 2023 by two Stanford-trained structural engineers, its platform deploys modular AI agents that read inspection photos, aerial imagery and public visuals to spot building-level vulnerabilities that traditional data misses - across earthquake, wildfire, windstorm and flood risk covering 99% of the US.
Karn Saroya
Karn Saroya is the co-founder and CEO of Re, a decentralized reinsurance protocol built on Avalanche that connects alternative capital to the nearly $1 trillion global reinsurance market. A Canadian-born, MIT-trained Fulbright scholar, he previously co-founded the YC-backed insurtech Cover and worked as a financial-services consultant at Oliver Wyman before deciding the insurance stack itself needed to be torn down and rebuilt on-chain.
Friendly
Friendly is a San Francisco-based AI company building an infrastructure layer for insurance decisioning. Its platform digitizes complex medical, financial and legal documents, summarizes records, automates underwriting and claims adjudication, and analyzes reinsurance treaties - turning unstructured paperwork into auditable, decision-ready insights for carriers, reinsurers and TPAs.
Safehub
Safehub turns any building into an IoT device for earthquake risk. Its proprietary sensors and cloud analytics deliver building-specific damage information within minutes of a seismic event, helping owners, insurers and emergency teams make faster, better decisions. The same sensor network powers a new generation of sensor-triggered parametric earthquake insurance designed to slash basis risk and speed up payouts.
Sixfold
Sixfold is a New York-based enterprise AI company building purpose-built artificial intelligence for insurance underwriters. Its platform learns a carrier's risk appetite, reads and summarizes complex submissions, surfaces cited risk signals, and deploys AI agents that research, write referrals, and advance cases - so underwriters spend their time on judgment instead of paperwork. The company serves global carriers, MGAs, and reinsurers across property & casualty and life & health, and has processed more than a million submissions for insurers representing hundreds of billions in gross written premium.
Natasha Alexeeva
Natasha Alexeeva is the Founder and CEO of Friendly, a San Francisco-based enterprise AI company that automates insurance underwriting, claims processing, and reinsurance treaty analysis using deep learning. Originally from Moscow, she holds a CS degree from Lomonosov Moscow State University and an MBA from Stanford. Before Friendly, she pioneered EMR-integrated asynchronous telemedicine as founder of GoGoHealth and led new service incubation at Amazon Web Services. Her platform processes 7,000 pages per hour at 95% accuracy, delivering the 85% efficiency gains she's made her personal mission.
