reThought Insurance (branded reThought Flood) is a technology‑first Managing General Agent (MGA) that builds data‑driven flood insurance products for residential and commercial customers in the U.S., using multi‑model AI risk scoring and precision underwriting to place capacity with A‑rated carriers on behalf of brokers and wholesale partners[8][5]. reThought was founded in 2017 as an InsurTech MGA focused on closing the private flood protection gap by combining advanced analytics, model convergence, and patent‑pending Flood Resilience Scores to price and underwrite complex and mid‑tier flood risks[3][5].
High‑Level Overview
- Mission: reThought aims to “inform and empower capacity to close the climate protection gap” by enabling private flood insurance through better data and underwriting[1][5].
- Investment philosophy / Key sectors / Impact on startup ecosystem: As an MGA (not an investment firm), reThought’s activity centers on insurance product innovation in the flood (climate risk) sector, partnering with carriers, reinsurers and brokers to expand private market capacity for flood risk rather than making venture investments itself[3][2].
- What product it builds: reThought builds flood insurance products and an underwriting platform that uses multiple flood models, proprietary data, and an AI‑based Flood Resilience Score to underwrite and price policies[5][8].
- Who it serves: The company serves insurance brokers, wholesalers, capacity providers (A‑rated insurers/reinsurers), and the end insureds — residential, commercial, specialty and high‑net‑worth properties[8][2].
- What problem it solves: It addresses underinsurance for flood, especially for complex, mid‑tier commercial and specialty risks, by offering more accurate risk assessment, broader coverage options, and pricing aligned to property‑level resilience[5][8].
- Growth momentum: reThought reports partnerships with A‑rated carriers and claims to have withstood major events (e.g., Ida, Ian) using its modeling approach; it has attracted investors and strategic partners including RISE Resilience Innovations and IA Capital Group and has grown its product offering since launch in 2017[1][3][6].
Origin Story
- Founding year and founders: reThought was founded in 2017 by insurance and insurtech professionals including Cory Isaacson and James Rice, who previously worked in insurance analytics and modeling; Isaacson has prior software executive experience and multiple patents[3][7][1].
- How the idea emerged: Founders framed the business around the observation that flood is the most destructive and underinsured peril in the U.S.; events like Hurricane Sandy highlighted the protection gap and motivated a data‑centric, model‑convergent approach to flood underwriting[1][5].
- Early traction or pivotal moments: Early positioning as a technology‑centric MGA, deployment of a patent‑pending “model convergence” engine and Flood Resilience Scores, and securing A‑rated capacity providers and investors such as RISE and IA Capital Group mark its early traction[1][3][5].
Core Differentiators
- Multi‑model, patent‑pending approach: reThought uses a “model convergence” engine that deploys multiple flood models rather than relying on a single model, aiming for more accurate flood frequency/severity assessment[1][5].
- Flood Resilience Score (FRS): The company’s proprietary FRS combines public and proprietary data and feeds an AI process to score individual buildings for resilience, which materially influences pricing and coverage terms[5].
- Product breadth and coverage terms: reThought emphasizes broader, risk‑based coverage (large aggregate limits, basement contents, loss of use, debris removal) that many standard flood products omit[5].
- MGA structure and carrier partnerships: Operating as an MGA, reThought places policies with A‑rated carriers and leverages those partnerships to scale capacity while retaining underwriting control and product agility[3][8].
- Broker/underwriter support and responsiveness: The company highlights hands‑on underwriting, program structuring, and fast quote turnaround as market differentiators for winning and retaining broker business[8].
Role in the Broader Tech Landscape
- Trend alignment: reThought rides the confluence of climate risk expansion, demand for private flood solutions, and the broader InsurTech move toward data, AI and model‑driven underwriting[5][8].
- Why timing matters: Rising flood frequency and severity plus persistent underinsurance create market opportunity for private insurers and MGAs that can price risk more granularly and manage portfolio concentration[1][5].
- Market forces in favor: Growing reinsurer and capital interest in climate risk transfer, regulatory and mortgage‑driven demand for flood coverage, and broker desire for placeable solutions for complex risks all support reThought’s value proposition[3][8].
- Influence on the ecosystem: By demonstrating that multi‑model analytics and building‑level resilience scoring can expand private flood capacity, reThought encourages carriers and investors to adopt more granular, data‑driven underwriting approaches across climate perils[5][1].
Quick Take & Future Outlook
- What’s next: Likely priorities include expanding distribution (brokers/wholesale), scaling capacity partnerships, continuing to validate and refine model convergence and FRS through more loss experience, and possibly broadening product lines or geographies within U.S. flood markets[8][5].
- Shaping trends: Continued climate change impacts, increasing data availability (remote sensing, IoT), and demand for parametric and resilience‑linked products will shape reThought’s path and create opportunities to integrate more real‑time and asset‑specific signals into pricing[5][1].
- How influence may evolve: If reThought’s model convergence and resilience scoring consistently produce better loss outcomes, it could become a reference MGA for private flood solutions and push incumbents toward multi‑model underwriting and resilience‑based pricing[1][5].
Quick take: reThought is a focused InsurTech MGA that applies multi‑model AI and proprietary resilience scoring to make private flood insurance more placeable and accurately priced, positioning it to benefit from rising demand for climate‑aware insurance solutions while needing ongoing claims experience and capital partnerships to scale materially[5][3][8].
