Saturday, Jan. 24th  | 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 day 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.

​Doors open at 9 am Saturday.

​Kickoff talks start at 9:30 with team formation taking place immediately after.

​We will have a focused 10-hour build sprint fueled by food and coffee.

​Building ends at 6:30pm, followed immediately by demos.

Winners to be announced at 8pm, Saturday

​First: $2,000 USD

​Second: $600 USD

​Third: $400 USD

​Other prizes are:

• ​Puentes by Antigravity: One team will be fast-tracked for interviews into the next Puentes by Antigravity cohort in San Francisco.
• Best use of Resend: New pair of AirPods per each team member.
• Best use of ElevenLabs: 6 months of their Scale tier ($330/month) for each team member.
• ​Best use of BlackBox AI: 3 months of their Pro Max tier ($40/month) for each team member.

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 10 hours

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

• Quality of the delivered prototype
  
• Adherence to the challenge/theme
  
• Use of AI
  
• Feasibility and practicality
  
• Creativity and originality
