Once connected, you can ask Claude things like:
  • “Who do we know that would make a great angel investor for us?”
  • “Who can introduce me to someone at Modal?”
  • “Find engineers in my YC group who have worked on distributed systems, and draft an intro request for the best three”
  • “Run a Happenstance research on Garry Tan, CEO of Y Combinator”
  • “Check my Happenstance credit balance”
People questions go to Happenstance Chat, which searches your network, explains who fits and who can introduce you, and drafts outreach. A reply usually takes 1 to 3 minutes. The credit check includes your auto-reload status and a link to manage API credits at happenstance.ai/developer/keys.
