About Greenoaks
Neil Mehta left D.E. Shaw in 2012, at age 27, and started Greenoaks with his friend Benny Peretz. The firm has been a registered investment adviser since its 2012 formation. Its first fund was about $50M. Later funds grew: Axios reported a $2.1B Fund V in 2023, slightly more than Fund IV in 2021, and Venture Capital Journal reported a $2.5B sixth fund that beat its $2.25B target. An SEC Form D for Fund 6 was filed in June 2025, according to ValueAddVC. Crunchbase and VCSheet list Mehta as founder and managing partner, Peretz as managing partner, and Ben Solarz, Patrick Backhouse and Neil Shah as partners. Genevieve Kahr is Partner and Head of IR. Greenoaks does not publicly name a single partner who leads its AI investing.
Greenoaks says it makes concentrated, long-term investments in generational teams. In a 2025 podcast interview, Mehta described a portfolio of roughly 55 core companies run by nine investment professionals. In AI it often leads. The firm led Anthropic's $65B Series H in May 2026 and co-led Simile's $200M Series B with Index Ventures in July 2026. It also led AIR Security's $40M seed and $50M growth rounds in August and September 2026. Third-party trackers list Scale AI, Safe Superintelligence, Sierra and Vercel in its portfolio. Greenoaks also invests outside AI, for example in Coupang, Wiz, Stripe, Figma and Rippling.
Greenoaks does not publish a check-size policy. Third-party aggregators put its initial checks at $25M to $75M, mostly Series A and Series B, with some earlier and later rounds. Treat that as an estimate, not a firm statement. Its recent AI activity has ranged from a $40M seed round (AIR Security) to a $65B Series H (Anthropic). Greenoaks led all three of those rounds.
