Are you passionate about gaming, sports, or travel? Have you ever dreamed of building a tech project that makes a real impact?

At the 10th CASSINI Hackathon, you’ll create bold, consumer-focused solutions powered by EU space data. With N3XTCODER’s commitment to sustainability and the common good, we’re bringing an impact-driven twist to this European-wide event – happening simultaneously in 10 countries over one weekend.

This is your chance to find co-founders, showcase your skills, and learn from world-class mentors – all while building something that matters.

The Challenges

Challenge #1: Immersive Gameplay with Space Tech

Imagine creating a game that doesn’t just entertain, but also engages players with the real world.

You could design a game where players solve environmental challenges using live space data.
Or build gameplay that evolves in real time through satellite updates.

How can space data make gameplay meaningful, not just fun?

Challenge #2: Space-Powered Performance in Sports

Sports connect people everywhere – but what if they could also drive positive change?

You might explore how GNSS can improve athlete safety and performance.
Or design training tools that are inclusive, adaptable, and sustainable.

How can sports powered by space inspire impact for both players and fans?

Challenge #3: Beyond Horizons – Travel Reimagined

Travel opens horizons, but it also carries responsibility.

You could design tools that help travellers make sustainable choices.
Or create immersive ways to explore the world without leaving a footprint.

How can space tech help us discover the planet while protecting it?

Who Can Participate?

No space-tech background? No problem. Curiosity and creativity are all you need!
No prior knowledge required: Use our online training library to get up to speed.
No team needed: Join solo and connect with other professionals during the event.
Not a programmer? That work just as good. We need designers, entrepreneurs, storytellers, and business minds, too!

The hackathon is open to students, early-career professionals, and experienced specialists alike.

CASSINI stands for Competitive Space Startups for Innovation Initiative. It is a European Commission programme that helps innovators and entrepreneurs turn space technologies into impactful solutions.

The CASSINI Hackathons are one of the main ways the programme achieves this goal, with events hosted in ten countries at the same time. This hackathon marks the fourth collaboration between N3XTCODER, Novaspace and the EU Commission.

Local Challenges in Berlin

Berlin thrives on turning ideas into action – and so will you. Over three days, you will:

Work side by side with mentors & experts
Develop your concept into something tangible – from idea to wireframes, a click dummy, or even a prototype
Strengthen your portfolio with a real project and entrepreneurial experience

That is why, by Sunday evening, you’ll have more than just an idea: you’ll have a pitch-ready solution with the potential to scale.

Prizes

Throughout the hackathon, teams will get full support to research, shape, and pitch their concepts. On the final day, a jury will select the winners of the local edition.

For the German (Berlin) edition, the winning teams can look forward to a total of 5 tickets to re:publica 2026, a Product Lab with N3XTCODER, and mentoring from our partner 42 Berlin.

Beyond that, the first-place team will advance to the international stage, competing against winners from nine other hackathon locations for cash prizes of up to 9,000€ (1st: 5,000€, 2nd: 3,000€, 3rd: 1,000€) and six months of mentoring.
