Investment Thesis

Brewer Lane Ventures is a pre-seed-to-Series B venture firm dedicated to fintech and insurtech, founded by John Kim (former President and CIO of New York Life) with operating partners drawn from senior leadership at New York Life, Prudential, and other major carriers. The firm differentiates itself through "operator-led" investing — diligence using carrier-grade metrics like loss ratios and combined ratios — and direct access to insurance-balance-sheet relationships, customer pilots, and distribution partnerships across P&C, life, and health insurtech. It deploys from an inaugural $175M Fund I, and its team includes alumni of XL Innovate, giving it deep continuity with one of the original dedicated insurtech funds.
