NFX
Founded by founders who state they built 10 companies with more than $10 billion in exits. The name stands for network effects, which the firm has studied for over 20 years and calls the number one way to create defensibility in the digital world.
Criteria: States it typically invests at pre-seed and seed, in the United States, Israel, Latin America and Europe, and that it underwrites two things: the founding team and the market opportunity. States it funds you first and funds you fast. Backed founders join The Guild, its network of more than 500 founders. Publishes 448 essays, a network effects manual describing 16 distinct types, a free three hour masterclass, and software for founders: Signal, a fundraising network connecting founders to investors, and Brieflink for sharing decks.
What this means for your pitchRead the network effects manual before you pitch, then name which of the 16 types your product builds and why it strengthens with each user. That is their underwriting language, and arriving fluent in it is the cheapest credibility available here. They state the best routes in are a warm introduction or Signal, their own tool, which is a door any founder can open without knowing anyone.
