Yujian Tang started the r/AI_Agents subreddit in April 2023. For the first year, it barely moved. Then it hit 9,000 members, he went on vacation, came back to 36,000, and now it's approaching 300,000. In this episode, Yujian talks about how that community grew alongside his event business (Seattle Startup Summit, 900+ attendees last year), his two failed startups, and why he just filed paperwork to launch his own venture fund.

Conor and Yujian dig into the mechanics of starting a fund from scratch (Delaware PO boxes, EIN numbers, lawyers), why AI startup valuations have doubled in the last two years, whether a one-person unicorn is realistic, and what failed founders learn that successful ones sometimes miss.
