That hardware background, honed further at climate-focused Prelude Ventures, shapes his specific investing lens at Congruent Ventures, which he co-founded with Abe Yokell in 2017: he focuses on real engineering risk in climate hardware rather than subsidy-dependent business models, evaluating complex physical systems most software-only investors can't meaningfully assess. Congruent has since grown into one of the largest early-stage climate portfolios in venture capital, with more than $1 billion raised across multiple funds and backing from CalSTRS, the Grantham Foundation, and other major institutional climate investors.
