SF1

SF1 is an early-stage venture capital firm based in San Francisco that invests in artificial intelligence companies. The firm states that it partners with AI-native founders - teams building at the technical edge - with the intention of supporting them from inception through IPO. Its remit is narrow by design: early-stage AI, rather than technology investing broadly.

The firm's stated criteria for founders combine three elements: distinctive product insight, a clear understanding of go-to-market, and the ability to attract exceptional talent. SF1 describes its ambition as backing companies early and helping build enduring, generational businesses - a long holding period that implies support well beyond the initial round.

Named portfolio companies number three: Catalyst, Tenkara and Supermemory. Fund size, check size, founding year and team composition are not disclosed. SF1's sector focus is artificial intelligence, AI-native technology and early-stage venture investing.
