Safe AI Fund

What Safe AI Fund does

Safe Artificial Intelligence Fund (SAIF) is an early-stage venture capital fund founded in April 2025 by Geoff Ralston, the former president of Y Combinator (2019-2022). The fund invests exclusively in startups developing tools to enhance AI safety, security, and responsible deployment, deploying $100,000 initial checks bundled with mentorship and network access. SAIF's published investment thesis spans eleven sub-areas including alignment tools, interpretability, security infrastructure, bio safety, governance and compliance, deepfake protection, and decision-making support.

SAIF does not develop or sell a technology product of its own; its core offering is capital plus operator support to seed-stage AI safety founders. The fund has built a portfolio of 24 companies — including AgentHub, Apollo Research, Goodfire, CTGT, NewsGuard, and Confident Security — spanning complementary safety themes from agent monitoring and adversarial verification to interpretability research and secure AI infrastructure. The team operates internal tools built with AI-assisted coding (notably an open-sourced CRM called VCRM) but has no proprietary models, patents, or AI research output.

The fund is operated by a three-person team: founder Geoff Ralston and partners Nick Ralston and Michael Ralston. Deal sourcing is driven primarily through Geoff Ralston's Y Combinator alumni network and personal angel-investing relationships, supplemented by inbound applications through the fund's website. Revenue mechanics for the fund itself are not publicly disclosed and would derive from standard venture fund economics (management fees on AUM plus carried interest on exits), with no exits yet visible given the fund's recent vintage.
