Are you ready to shape the future of AI? Come to the YC Office and help build the next generation of AI Coding Agents—tools that can build websites, games, solve coding problems, and anything else you imagine.

🎯 Choose Your Track:

Web/Mobile – Build agents that can design, deploy, and manage full-stack websites on command.
Game Genesis – Craft AI that creates games—from concept to code to playable demo.
Autonomous Reactive Agents: Build software that changes itself. Projects must respond to non-human signals — sensor data, APIs, time, environment, etc. — and autonomously adapt functionality, structure, or behavior. No human prompts at run time.
Just-in-Time Software - Software that changes as the user uses them. Ex: Heads Up displays, CRM that changes based on user activity patterns
