Four Rivers Group
Four Rivers Group operates as a technology-focused venture firm from San Francisco, founded and led by Managing Partner Farouk Ladha alongside Managing Partner Dan Scholnick. The firm frames itself around multiple fund categories, though it does not publicly disclose total assets. Strategy spans early-stage Seed through expansion and late-stage Growth, with a portfolio concentrated in enterprise software, cybersecurity, AI, and digital health. Known positions include BillionToOne (which began trading on Nasdaq in November 2025 after a $314M IPO), Rula, Outreach, and Dtex Systems. The portfolio page also lists open-source infrastructure plays like Docker and Yugabyte, suggesting technical adjacency to developer-tooling markets. Geographic focus appears predominantly North America, with select global deals in markets such as Israel. The firm's website names two Managing Partners, an AI Partner (Fiona Rivers), and an advisory board featuring NEA's Scott Sandell and Warburg Pincus's Chris Brody. In May 2024, Dtex Systems raised $50 million led by Alphabet's CapitalG — a syndicate relationship that reflects the firm's co-investment network. No data is public on total professionals or additional offices. Four Rivers blends direct venture investing with a strategic limited-partner model: Lew Cirne (founder of New Relic) and Adam Messinger (former CTO of Twitter) sit as Strategic Limited Partners, a structure that embeds operating executives into the fund's sourcing and due-diligence apparatus rather than keeping them at arm's length.
