About NFX
Most directories list NFX as founded in 2015, while PitchBook gives 2014 and notes a former name, Ooga Labs. The firm's October 2021 Fund III announcement named James Currier, Pete Flint and Gigi Levy-Weiss as general partners, and added Omri Drory to run NFX Bio and Morgan Beller to lead its crypto work. NFX describes offices in Silicon Valley and Israel. NFX's 2021 post says the firm had seeded 25 unicorns by then, including DoorDash, Lyft and Patreon. Portfolio founders can join The NFX Guild, an invite-only network that one source describes as 500-plus founders.
NFX's generative AI page lists portfolio companies, including EvenUp, an AI legal technology company the firm backed at seed. Its blog explains why it backed Maisa, an enterprise AI workforce company, before that company raised a $25M seed from Creandum and Forgepoint. NFX also appears on Signal's list of top AI seed investors and on its top AI pre-seed list, both voted on by the startup community. A third-party 2026 ranking counts 28 AI seed checks from NFX in 2025 and 2026. Fund IV is reported to name AI as a lead theme alongside bioplatforms, space and security. In its Maisa post, NFX says it first invested because the company addressed trust, no-code digital workers and a technical team, which it saw as blockers to enterprise AI adoption.
NFX's Fund III post says the firm is built for pre-seed and seed companies. Superscout also lists Series A. Check sizes vary by source: EverythingStartups and Growth Equity Interview Guide cite $1M to $5M, Qubit cites a typical $1M to $2M seed check, and Capitaly estimates an average of $800K to $1.2M. These are third-party estimates, not figures from the firm. Qubit also notes a nine-day FAST program for seed deals with a response promised within three business days.
