01 Advisors
Growth fund led by former Twitter CEO Dick Costolo and COO Adam Bain investing in late-stage companies.
Dick and Adam are the rare VCs who actually know what it's like to scale a rocket ship — they lived through Twitter's wild growth and all the chaos that comes with it. This makes them unusually helpful for founders hitting scaling walls, but they're also pretty selective and won't sugarcoat things if your metrics aren't there. They're particularly strong in AI infrastructure where their technical judgment and network really shine. The fund is still relatively new but has already landed some impressive logos. They tend to move fast on deals they like but can be tough to get in front of initially.
