Sarah Guo, Greylock's youngest general partner, founded Conviction in 2022 and has since backed six of the 21 AI-native companies valued at $10 billion or more.
Guo's track record at her early-stage venture firm positions her as one of the most influential investors in artificial intelligence. Her portfolio includes six of the AI sector's most valuable startups—representing nearly 30% of all AI-native unicorns that have achieved $10B+ valuations.
Before launching Conviction, Guo built her reputation at Greylock Partners, becoming the firm's youngest general partner. Her early identification of AI opportunities has resulted in significant returns as the sector experienced explosive growth.
According to reporting from Colossus, Guo maintains a contrarian stance against some of the industry's largest players, suggesting her investment thesis diverges from conventional wisdom about which AI companies will ultimately dominate the market.
The success of Conviction demonstrates that specialized, focused venture funds centered on emerging technology waves can outperform traditional generalist firms when led by investors with deep domain expertise.
