AI-native software studio · São Paulo

We think. AI writes. You sell.

We build SaaS, online stores and internal tools with AI agents on the keyboard and experienced people in charge. What used to take a quarter ships in weeks, and the code is yours.

No pretending it isn’t AI.

    

      
We are proud vibecoders. Every line starts as a conversation with an agent, then goes through human review and tests before it ships.

      
    
        
  • AI types. Agents write, refactor and test most of the code, around the clock.
    • 
        
  • People decide. Architecture, business rules, security and what goes live stay with the people accountable for them.
    • 
        
  • You own it. Repo, database and domain are in your name. You see everything that was built and pay no platform rent.
