It's Monday morning. The hackathon is over. You're back at your desk (or in your bed, recovering). And somewhere on your laptop, there's a project that didn't exist 48 hours ago.

What happens to it now?

For most hackathon projects, the honest answer is: nothing. They get pushed to a GitHub repo that never gets another commit. And that's completely fine. Not every project needs to become a product. Sometimes the value was in the building, the learning, and the experience.

But sometimes — sometimes — you've built something that deserves to keep going. Here's how to tell the difference and what to do either way.

Not every hackathon project should survive the weekend. But a few signals suggest yours might be worth continuing:

People outside the hackathon are interested. If you described your project to someone who wasn't there and they said "Wait, can I use that?" — pay attention. That's market signal, even in its smallest form.

You solved a real problem. Not a contrived hackathon prompt, but something that genuinely bothers real people. If you built the project because you personally experience the problem, that's an even stronger indicator.

The team wants to keep going. This one is underrated. Building a product is a long road, and the biggest factor in whether early-stage projects survive isn't the idea — it's the team. If your teammates are texting about features on Monday, you've got something rare.

That last point deserves emphasis. Research by Choi et al. (2023), published in the Review of Economics and Statistics, showed that the early team members of a startup shape the company's trajectory for ten or more years. The founding team's skills, dynamics, and working relationships leave a lasting imprint on everything that follows. If your hackathon team has genuine chemistry — if you communicate well, complement each other's skills, and actually enjoy working together — that's not just a nice weekend memory. It's the seed of something potentially significant.

Continue development. Set up a proper repo, create a roadmap, and start iterating. Meet weekly — even 30 minutes keeps momentum alive. The biggest risk at this stage isn't building the wrong thing; it's losing momentum entirely.

Open-source it. If you built something useful but don't want to maintain it as a product, put it out there. Write a solid README, clean up the code enough that someone else can run it, and share it. Other people might pick it up and take it further.

Submit to startup competitions. Many universities and organisations run pitch competitions, accelerator applications, and grant programs. A working prototype from a hackathon is a strong starting point — it shows you can build, not just talk.

Use it as a portfolio piece. Even if the project goes no further, it's proof of what you can do. A working hackathon project with a demo video demonstrates execution speed, creativity, and technical ability better than almost anything else on a resume.

If you decide to keep building, here's the honest path forward:

Find actual users. Not your friends. Not your teammates. Real people who have the problem you're solving. Put the prototype in front of them and watch what happens. Do they understand it? Do they try to use it the way you intended? Where do they get confused?

Get feedback before adding features. The instinct after a hackathon is to add everything you didn't have time for during the event. Resist that instinct. Talk to users first. You might discover that the features you planned don't matter, and the thing users actually need is something you hadn't considered.

Iterate in small loops. Build a little, test a little, learn a little. Weekly cycles work well for side projects. Ship something every week, even if it's small. Progress compounds.

Have the honest conversation with your team. How much time can each person commit? Who's taking point on what? Is this a side project or something more serious? Misaligned expectations kill more post-hackathon projects than bad ideas do.

If the project stops here, don't let it vanish entirely. A few small actions preserve the value:

Document what you built. A brief README covering the problem, the solution, how to run it, and what you'd do next. Future you (or a future employer looking at your GitHub) will thank you.

Record a demo. A 60-second screen recording of the project working. This is portfolio gold and takes almost no effort to create.

Write about it. A short blog post or social media thread about what you built, what you learned, and what surprised you. This is good for your personal brand, and it often sparks interesting conversations and connections.

Add it to your portfolio. Whether that's your personal website, your LinkedIn, or your GitHub profile. Hackathon projects signal initiative, speed, and range.

This isn't a fairy tale — it's a real pattern. GroupMe started at a hackathon and was acquired by Microsoft. Carousell, now valued at over a billion dollars, began at a hackathon. Zapier's earliest prototype was a hackathon project. Countless smaller companies trace their origins to a weekend where a few people built something together and decided to keep going.

You don't need to start a company after every hackathon. But it's worth knowing that the path exists. The combination of a working prototype, a validated problem, and a team that clicks is exactly how many real companies begin.

If you feel that spark — if the team is energized, the problem is real, and you can't stop thinking about it on Monday — lean in. The hackathon gave you a head start. What you do with it is up to you.
