Cambrian Ventures

Rex Salisbury worked as a software engineer before becoming a fintech investor at Andreessen Horowitz, where he built one of the best-networked founder communities in the category. In 2022, he used that network to launch Cambrian Ventures as a solo general partner, built around the thesis that fintech has captured only a small share of global financial-services value and that meaningful new category formation is still ahead. Salisbury has kept Cambrian focused exclusively on early-stage fintech through two $20 million funds, even as the broader venture cycle made specialist strategies harder to sustain.
