The event

Software ate every industry except the ones that build the world.

Housing, transit, energy, construction — the biggest under-digitized industries on the planet, and almost nobody points student builders at them. For one weekend a year, we do. Real briefs from industry, real judges, AI tools encouraged from the first commit.

Questions

Asked often, answered here

Who can participate?
Anyone 13+, anywhere in the world — students, new grads, working engineers. No infrastructure background needed: the briefs explain the domain, and every track is approachable from a general software stack.
I've never done a hackathon. Is this for me?
Yes. First-timers are a huge part of the field. Mentors are on call all weekend, the Friday workshop covers building fast with AI tools, and team formation happens in Discord right after kickoff if you're coming solo.
Can I use AI tools?
Encouraged, not just allowed. Coding assistants, LLM APIs, generation tools — all fair game. You're judged on what you shipped against the brief, and on whether you can explain how it works.
What can I prepare beforehand?
Anything except project code. Environments, accounts, boilerplate, your team — all fine. Code written before the clock starts is grounds for disqualification; finalists walk judges through their commit history.
I'm not in North America. Will the times work?
The timetable above converts to your timezone with one tap, mentors are staggered across regions, and the big moments are streamed and recorded. If a finalist demo slot lands at 4 AM for you, we'll work around it.
What does it cost?
Nothing. Applying and competing are free, and sponsor-provided credits and tools are issued to every team at kickoff.

The city's waiting.

Applications open October 2026. Free, remote, 48 hours — and the industries that need you most.
