Tracks & Challenges
MEGATHON is one weekend, one main race, and a dozen ways to win. Bring your own startup, build it for real, and aim it at whichever tracks fit. Most tracks stack — you can chase several at once with a single build.
The headline prizes. Where the main-stage finals are won.
How you win
Most hackathons measure features. MEGATHON measures founders. Anyone can build something cool in 48 hours now — technical complexity isn't the bottleneck; whether you can build a company is. Judges score five things, and Execution Power carries the most weight: what you ship between Friday night and Sunday is the whole point.
The Friday-to-Sunday delta — what you actually built, shipped, and validated in 48 hours. A solo dev who shipped from zero beats a funded team that just polished a landing page.
Does it work? Is it well-built and genuinely AI-native — or a wrapper around an API call? Craft, design, and the quality of the idea.
Real market, real wedge, real path to revenue. Is this a business or a feature?
Your unfair advantage. Why this, why now, why you — and where it goes if it works.
Do you know how this actually reaches people? The go-to-market reflex that separates builders from founders.
How you win
Did you launch something real on Base44 and pull real traction over the weekend? That's the question.
Is this solving a real and meaningful problem?
How effectively did the team use Base44 to launch their product?
Real evidence of demand — signups, users, payments, customer interviews, partnerships, waitlist growth, engagement metrics.
A thoughtful launch, distribution, or acquisition strategy.
Can the team clearly say what they built, who it's for, why it matters, and why now?
How you win
Build with the Devin API as an autonomous infrastructure layer — programmatically trigger and control Devin agents to solve real-world problems. Devin as the product, not just a tool.
How to enter
Devin commits in your repo history.
Judging criteria
Full judging criteria are being finalised with Cognition and shared before the weekend.
You can enter as many tracks as your build fits. The sponsor and special tracks each judge their own way — set with the partner and shared before the weekend.
Plug in a platform and win on top of the main race — enter as many as you like.
Skip the data — plug in Cala, get flown to Barcelona.
Use Cala as your public data source: structured, sourced JSON for any real-world entity. Opt-in, and combinable with any other MEGATHON challenge.
The best voice-first AI build.

The best creative product built on Pixverse.
Build a real product with Pixverse in the core workflow — generative agents, video-first apps, creative tooling. A working product, not just a demo reel.

For unruly, unreasonable founders.
Build a viral B2C company over the weekend, start selling during MEGATHON, and commit publicly to €1M ARR in six months. Hosted at the Tulip Founders Camp — tents and fireside included.
Build in the open. Share the messy middle.
Build with the door open — public commits, your journey shared as it happens, the messy middle on display. The content heart of MEGATHON.
The audience favorite.
The crowd decides. The build that wins the room and the livestream takes it — tracked live on the leaderboard.
