AI changed what a small team can build in a weekend.

We want to see how far you can take it.

The AI Builders Hackathon is for people who build with AI, whatever their job title: engineers, product people, designers, founders. If you ship with coding agents, prototype with no-code tools, or keep finding new ways to make AI do useful work, this is for you.

The theme is personal finance. The exact challenge is revealed on Friday at 18:45, so everyone starts from the same line. Then you have 40 hours to turn it into something that works.

Ship the real loop. Mock on purpose. Say which is which.

■ real:
the core flow works end to end, live, in front of the judges
□ mocked:
anything you faked to get there, listed in your submission

Mocking is often the smart move. Hiding it isn't: an undisclosed fake costs points.

Fresh code.
No real money.

  • 001Use any AI tool, model, coding agent or no-code builder. The more you get out of them, the better.
  • 002Everything you show is built after the reveal. Libraries, frameworks, templates and your own agent setups are fine. Judges may check commit history.
  • 003No real money moves and no one else's real data. Use sandboxes, test modes, synthetic data or your own.
  • 004Demos show the working product. No slides.
  • 005Every submission lists what's real and what's mocked.
  • 006What you build is yours.

Startup Hungary is how Hungary’s founders pay it forward. Its founder board is 40+ scale-up and post-exit entrepreneurs, from SEON, Bitrise, Prezi, Shapr3D, Turbine, Tresorit and more, who have shown that global companies can be built from Hungary. The non-profit brings the startup scene together through events and research, passes on what those founders learned, and works with policymakers to remove barriers for high-growth startups.


Myner builds and operates proprietary AI-native Consumer Panels & Agentic Flywheels that close the loop from insights to outcomes for the world's leading brands. From discovering and validating breakthrough product innovations to standout marketing campaigns and expanded retail sales distribution, Myner harnesses proprietary data and methodologies to give its brand clients an unfair advantage.

// faq

Before you ask.

Does it cost anything?

No. Participation is free.

Is everyone accepted?

No. We expect more registrations than seats, so we pick the strongest mix of builders based on what you tell us. Approvals are rolling and seats fill as we go, so apply early. You'll hear back within a few days.

Do I need a team?

No. Register solo and you'll form or join a team on Friday night. [We'll also open a channel for approved solo builders so you can find teammates before the event.] Teams are 2–4 people, and lineups lock on Saturday at 10:00.

Can I build alone?

No. Solo registration is fine, but everyone builds in a team of 2–4.

What's the challenge?

The theme is personal finance. The exact challenge is revealed on Friday at 18:45 so everyone starts from the same line.

Can I prepare in advance?

Set up your tools, accounts and agents as much as you like. Product code, designs and content start after the reveal.

Is food provided?

Yes: pizza on Friday night, lunch on Saturday, more pizza on Saturday night, breakfast on Sunday, plus snacks and coffee throughout. Tell us your dietary requirements when you register.

Is the venue open overnight?

Yes, from Friday 17:30 until Sunday's close. There are no beds, so bring whatever you need to rest.

What should I bring?

Laptop, charger, and anything else you need to build.

Who can take part?

Anyone 18 or older. Everything happens in English.

Who owns what we build?

You do.

Is this a recruiting event?

It's a builders' event. Myner is hiring and says so openly. If you want to hear about their open positions, tick the box when you register. It has no effect on judging.

My plans changed. What should I do?

Cancel on Luma so someone on the waitlist gets your spot.

How do I contact you?
