Guava Voice AI Hackathon: Build Night Boston

Build a working voice agent in one night. Guava Build Night comes to Cambridge. Doors at 5:30, kickoff at 6:00, code freeze at 8:30, awards at 10:15, hard stop at 11:00. We ran the first one in San Francisco on August 29. Fifty-seven people came, and thirty-one working voice agents got built and demoed in about two hours. Five separate teams independently built a supervisory layer that listens to an agent in real time and stops it before it breaks a rule. Nobody asked them to. WHAT YOU GET Cash prizes across the top three, plus side prizes. Food, drinks and zero-proof options all night. Guava engineers at the office hours desk from start to finish. Free Guava minutes on your own account to keep building afterwards. ONE RULE To be eligible, your agent has to place or answer at least one real phone call. A demo that never rings does not count. WHO SHOULD COME Developers and students who want to ship something that talks. Healthcare, finance, insurance, collections, legal, and anywhere else a phone call has rules attached. Teams of one to four. You can form a team when you arrive. WHAT TO BRING A laptop and a charger, wired headphones if you have them, and your phone. Run the install before you leave home rather than at the door. The exact venue is being confirmed and will be announced here shortly. It will be a short walk from MIT.
