Technology-centric MGA writing complex commercial flood and HNW residential flood risks with an engineering-first underwriting model; remains independent with ~44 employees and no round since a Jan 2023 $10.5M Series B. Engineering-first underwriting model reportedly delivering low loss ratios, attracting A-rated capacity providers — a self-reinforcing flywheel in a category where capacity access is the binding constraint.
Current state: Rethought Insurance remains an independent commercial flood MGA operating as reThought Flood (Broomfield, CO); ~44 employees as of Jan 2026 per Tracxn. Last publicly disclosed round was a $10.5M Series B in Jan 2023. No acquisition found.
Large, underpenetrated, structurally growing category — commercial flood is a legitimate multi-billion white-space where an engineering-underwriting MGA can compound rapidly if it secures A-rated capacity.
