Wow, I'm jealous. Good luck!
You're in pretty rarefied air. There's only 20-25 a year and they've been doing it for ~10 years. So maybe there are 250 Thiel Fellows total. [1]
There's a list of notables on [1] that you might be able to reach out to, or maybe you could contact someone doing admin at the Fellowship to connect you.
