Accel: The Quiet Firm Behind Facebook, Cursor, Nebius, Lovable, Vercel

Accel Partners Arun Mathew, Miles Clements, & Matt Weigand join Sourcery to go deep into the lore of the quiet, yet legendary, Silicon Valley firm. We go back through Accel's 40 years of history, starting with the 10% Facebook stake and the secondary they modeled at 5X, which under-shot the outcome by an order of magnitude, and how the firm now runs a global AI portfolio spanning chips, neoclouds, labs, and applications, with exposure across Cursor, Anthropic, and Nebius. The three have invested together for 15 years, and they break down how a generalist team wins competitive deals against flashier names, why late-stage returns are starting to match early-stage top quartile, and how check sizes moved from a $480M first growth fund to single investments north of $500M and, at times, over $1B. Topics include Matt's $150M Nebius PIPE, now up 13X, and its $26B Meta deal; the "agentic influence" thesis behind the Lovable investment; Supabase growing 350% on nearly all inbound at 9M developers; Cyera's path from Series A to the highest-valued private security company; token maxing; and three trillion dollar IPOs on the horizon. We also get into the hot topics moving tech, AI, and investing right now: the agent economy and real enterprise adoption, the inference buildout and whether infrastructure is the rate limiter, AI optimization replacing SEO as the new distribution channel, the concentration of capital into a handful of late-stage rounds, security as an AI tailwind rather than a casualty after Mythos, the race toward $10 trillion companies, and what it means for retail when SpaceX, and others, finally hit the public markets.
