Gigi Levy-Weiss is a serial founder and a Founding Partner at NFX. NFX is an early-stage firm that has established itself as one of leading experts in network effects. We talked about network effects, AI agents, the importance of speed of exectuion, why first-mover advantages are overrated, and how NFX has built its own brand, systems, and network effects.
We also covered:
-
Going global without going local — Despite a 10-hour time gap between Israel and Silicon Valley, NFX partners rejected the easier path of separate regional funds, instead building a fully integrated, unified investment process based on trust, asynchronous communication, and individual founder meetings.
-
Content as a competitive weapon — Early, sustained investment in short-form, actionable founder content gave NFX outsized market presence. Articles like the “Network Effects Bible” turned content into a persistent competitive advantage, positioning NFX as the definitive voice on network effects.
-
AI's future is agent-to-agent, not agent-to-human — Gigi sees current AI implementations as merely transitional (agent-to-human workflows), predicting the true revolution lies in agent-to-agent interactions, cutting entire human-dependent processes from months down to minutes.
-
B2C is AI’s biggest opening — Contrary to many investors betting big on AI-driven enterprise SaaS, Gigi argues consumer and SMB markets offer more attractive opportunities. Large enterprises will adapt quickly, limiting disruption, while SMBs and consumer verticals are ripe for agent-first innovation.
-
First-mover advantage is overrated — Gigi challenges the widely-held VC belief in the inherent value of being first. Pointing to past failures, he argues that "being great is more important than being first," and successful fast-followers often become category leaders.
-
Great products rarely sell themselves — Founders mistakenly obsess over perfecting product details (“product delusion”), yet distribution and defensibility usually matter more. NFX advocates for “product-market-network-distribution fit,” highlighting cases like Craigslist where distribution outshone product polish.
-
VC needs its own disruption — NFX built internal VC tooling (“The Force”) and founder-focused products like Signal and BriefLink, seeing tech-driven innovation as essential for winning deal flow. They reject the outdated assumption that every industry except VC itself can be disrupted by technology.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
