Running
Hackathon

For the crazy ones. The ones who read “you can only build while you run” and think obviously. One rule, all day, good vibes only.

and build at the same time

You run.
You build.

Teams of three ship a real AI product in a single day, and only the teammate out on the loop can touch it. Voice in from a phone, cloud agents doing the work, output live on the screens at home base. Loud music, sore legs, and something real by sundown.

  • 01

    While you run

    Only you can build. Hands free from a phone. Voice in, agents out.

  • 02

    When you stop

    The agents pause. Nothing moves until the next runner is out there.

  • 03

    How you win

    What you built × how far you ran. Neither one alone is enough.
