Agents Hackathon in Brazil

The First Overnight Agents Hackathon In Brazil Friday, Jan. 24th – Saturday, Jan. 25th | Cubo Itaú | Application Required Join us in São Paulo for a focused, in-person hackathon to build AI agents. We’re bringing together 100 ambitious engineers from across Brazil to spend a weekend hacking on agents across modalities — email, voice, messaging, and more — with live demos, prizes, and a direct bridge into the San Francisco AI ecosystem via Puentes by Antigravity. Capacity is limited; applications are required. This is for you if you’ve shipped agents, tools, or you can show relevant repos and side projects. This hackathon is a way for you to connect with the scene in San Francisco and other ambitious engineers in Brazil. What to Expect Doors open at 6 pm on Friday. Kickoff talks start at 6:30 with team formation taking place immediately after over dinner. Focused building all night fueled by a ridiculous amount of snacks, coffee, iced lattes, and four different types of energy drinks. Speakers and panels (to be announced) throughout the day Saturday, with building ending at 6pm—exactly 24 hours. Winners to be announced at 8:30pm, Saturday Prizes We’re still assembling a prize pool. Already confirmed: one participant will be fast-tracked for early acceptance into the next Puentes by Antigravity cohort in San Francisco. This is not limited to the “overall winner” — we’re looking for people with strong execution, taste, and long-term potential. We’re curating a small group of world-class judges. Still to be announced. Hosts This hackathon is organized by Puentes by Antigravity. Puentes is a curated one-week program in San Francisco to bridge the best talent in Latin America to the city. Antigravity is an AI-native seed fund in San Francisco. Selection & Format

Why This Weekend Exists Brazil has serious talent, but most of the action still feels “somewhere else.” This weekend is a small step toward fixing that:  

A room of the best engineers

Real products shipped in 24 hours

A direct bridge into an ecosystem that usually lives in San Francisco
