What you likely need
You're a two-time YC-backed founder fresh off an acquisition, and the right Festival events will help you figure out your next move — whether that's a third company, angel investing, or a senior operator role. The highest-leverage gatherings for you right now are ones that reconnect you with YC W21/W22 alumni who can become co-founders or early hires, and rooms full of PropTech and AI-workflow investors who already respect your HOAi exit. A few well-placed positioning and reflection events will also help you crystallize your story before you go loud about what's next.
