- If you're fundraising: Prioritize events with named funds in the title (Flybridge, Goanna, Antler, MGV.VC). The VC is physically there.
- If you're hiring engineers: dev/ai/nyc, AI Engineers Tech Talk, and the Agentic Engineering Hack are where senior AI engineers actually show up.
- If you're selling B2B: GTM Eng NYC, Dive Club LIVE, and the NYC B2B dinners put you in the room with buyers and operators.
- If you're early and exploring: Demo nights (South Park Commons, NYC AI Demos) let you survey the landscape without committing to a vertical.
- If you're burned out on networking: Tech Pickleball or Antimetal at Carbone. Lower social tax, same network density.
