Ben and Marc’s 30‑Year Partnership

In this feed drop from Uncapped, Jack Altman sits down with a16z co-founder Ben Horowitz to unpack the founding bet behind Andreessen Horowitz. VC should be a better product for entrepreneurs, built on real operating experience, real networks, and real support.

Ben shares how he and Marc Andreessen have worked together for 30 years, how they make decisions, and what it takes to scale a venture firm without losing the edge that actually helps founders. They also dig into why boards matter, how platform teams can change what partners do day-to-day, and the difference between “heat-seeking” investing and conviction-driven company building, especially in sectors like AI and crypto.
