about this event
Built Young Teen Hackathon — Build for Good · Sunday, September 20, 2026 · 1:00–5:00 PM · Markham, ON · Ages 12–18 · No coding experience needed
Build a startup that matters — in one afternoon. In four hours, you'll go from an idea to a working product. We'll teach you to vibe code with AI, you'll team up, build a real app around a problem worth solving, and pitch it to the room. No experience required — just come ready to build.
This isn't a coding class. It's a startup sprint. You'll find a real problem, build a real solution, and learn to pitch it like a founder.
Build around one of four themes:
📚 Education Access — make learning work for more people
🧠 Mental Health — help people feel better and cope stronger
🌍 Climate & Sustainability — build for a livable planet
♿ Elderly & Disability — design for people the world overlooks
Why this theme? These four themes mirror the challenge areas of the Diamond Challenge — one of the world's leading high school entrepreneurship competitions. This hackathon is a chance to test-drive a real venture idea in the same problem spaces top student founders compete in, and to walk away with a working product and a pitch you could take further.
How the day works:
Learn to vibe code — a hands-on workshop; build your first AI app live. Team up — join a crew and pick your problem. Build your startup — turn a real problem into a working product. Pitch it — present to the room and our judges.
By 5 PM, you'll have built and pitched a real startup. Some of the best ideas won't stop here.
What to bring: a laptop, a charger, and one problem you wish someone would solve. Spots are limited. Register now to claim yours.
