The Nobu Dinner and the 7-Hour Partnership Conversation
At 38:22 · chapter starts 34:10
The formal origin of the a16z-Flow partnership can be traced to a dinner at Nobu in Miami. Andreessen had spotted a Wall Street Journal piece about Neumann deploying capital into residential real estate — he called, they met again, and eventually Horowitz joined for what became a 7-hour dinner. DG (David George) and Chris Dixon were also at the first gathering. Neumann arrived wanting to discuss lessons from WeWork; Andreessen told him to skip it — they already knew more about his mistakes than he might expect. What emerged instead was a genuinely honest conversation about Neumann's psychology. Horowitz had watched the WeWork story carefully and knew its emotional architecture well.

Andreessen argues that to deliver Flow's vision end-to-end, vertical integration was the only path — even if it meant a VC fund owning real estate.
