How to Turn a Hackathon Project Into a Startup
Some of the best startups began as a weekend hackathon project. Here's how to tell if yours has legs — and how to take it from demo to company.
First, be honest: is it a product or a demo?
A hackathon project proves you can build something. A startup proves people want it. The gap between the two is real demand. Before you invest months, ask: who has this problem, how badly, and would they pay (in money, time, or attention) for your solution? If you can't name a specific, reachable user who wants this, that's the first thing to fix.
Validate before you build more
The biggest mistake post-hackathon founders make is polishing the product instead of talking to users. Get your demo in front of ten real potential users. Watch them use it. Ask what they'd pay for and what they'd never use. Their reactions — not your assumptions — tell you whether to keep going.
- Talk to at least 10–20 potential users before writing more code.
- Look for people who ask 'when can I use this?' — that's real demand.
- Be willing to change or drop the idea if the signal isn't there.
Get the team right
Your hackathon teammates may or may not be your co-founders. A startup needs people who are committed for the long haul, share the vision, and cover the key skills — usually someone who can build and someone who can sell. Have the hard conversation early about roles, equity, and commitment.
A great hackathon team wins a weekend. A great founding team survives the two years after it.
Build a real MVP
Your hackathon build was optimized for a demo. An MVP is optimized for real use — it needs to be reliable, usable, and focused on the one thing that delivers value. Cut everything else. Get it into users' hands quickly and improve based on how they actually use it.
Find support: incubation, mentorship, and funding
You don't have to do it alone. Incubation programs give early founders mentorship, resources, and a network to move faster and avoid common mistakes. This is exactly where a hackathon with an ecosystem behind it becomes powerful — the event ends, but the support continues.
From DEVTHON demo to real venture
DEVTHON is built for this journey. Beyond the 36-hour sprint, standout teams get access to startup incubation, mentorship from founders and investors, and the broader DevUp Ecosystem. If your project has legs, DEVTHON is designed to help you take the next step.
