After three decades studying catastrophe risk from boardrooms in New York and Bermuda, Steve Weinstein chose Florida for his founder’s bet. Mangrove’s strategy is equal parts underwriting discipline, global reinsurance and a stubborn belief that difficult markets can still reward patient builders.
A voluntary builder pact became part insurer, part referee and part trade school. Its most useful product may be the feedback loop that catches expensive construction problems before they multiply.
Florida home insurance has punished tourists, homeowners and insurers alike. Mangrove's answer is a selective book of business, local agents and layers of capital built to survive the weather rather than wish it away.
Most insurers pay a claim and wave goodbye. People's Trust built its own construction company so it could show up with trucks instead.

At Slide, Rachel Carr translates a technical, catastrophe-exposed business into a brand homeowners, agents and public-market investors can understand. Her career traces a practical path from ESPN and Cigna to two public-company journeys in Tampa.
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.

Eventual is a New York-based climate fintech that helps American property owners escape the whiplash of rising home insurance costs. Its flagship product, the Premium Lock Guarantee, uses AI models trained on data from 20 million homes and 150,000 commercial properties to forecast how a property's insurance premiums will move over the next several years - and reimburses homeowners when their bills climb past that forecast. Sold through a network of more than 1,000 independent insurance agents and available in all 50 states, Eventual turns unpredictable, climate-driven premium spikes into a fixed, multi-year expectation. The company raised a $7.5 million seed round in July 2025 led by AlleyCorp and Upfront Ventures.
Geolava is a San Francisco startup building a world model for the built world - a spatial intelligence layer that fuses satellite, LiDAR, aerial, street-level and government data into a foundation model you can query in plain language. It lets real estate owners, investors, lenders, insurers and operators analyze, underwrite, monitor and forecast physical assets, turning slow, manual property surveying into predictive property intelligence.

Dan Preston is the co-founder and CEO of Stand Insurance, a San Francisco-based insurtech company using physics-driven AI and digital property twins to insure climate-impacted homes in wildfire and hurricane zones.

At Stand, he has raised $65 million across two rounds and grown the company to over $1 billion in insured value within its first year, with expansion into Florida's catastrophe market. His vision: insurance as an active driver of community resilience, not just a financial safety net.
