Refactor Capital is an early-stage venture capital firm based in Burlingame, California, founded in 2016 by Zal Bilimoria, a former partner at Andreessen Horowitz’s Bio Fund. The firm focuses on investing in startups that leverage technology to address fundamental human challenges, particularly in the bio, climate, and hard tech sectors.

In June 2024, Refactor Capital closed its fourth fund, raising $50 million, with 90% of the capital coming from existing investors. The firm plans to lead pre-seed and seed investments, typically committing $1-2 million per company, aiming to support 20-25 startups over the next three years.
