NFX is a venture capital firm best known for its focus on network effects as a core investment thesis for early-stage startups. The firm publishes a large library of content (445+ posts) covering topics such as fundraising, growth, leadership, investment memos, psychology, and network effects, and sends a weekly newsletter read by over 322,000 startup teams. NFX has backed companies across sectors including health tech, aerospace, legal AI, biotech, quantum computing, and consumer software, with recent portfolio companies and news including Starcloud, Stoke Space, EvenUp, Centivax, Q-Factor, and Gizmo. Every founder NFX backs becomes part of the 'NFX Guild,' a network of 400+ founders. To support founders beyond capital, NFX has built seven software products from scratch, including Signal (a fundraising network for founders), Brieflink (private, trackable fundraising deck links), and the NFX Masterclass (a 3-hour video course on network effects).
