Join the world's largest Fixathon in Stockholm!

4-5 December 2026
Norrsken House Stockholm

Hundreds of problem solvers. One mission: to prompt what matters.

Get ready for the Stockholm edition of the world's largest Fixathon: a global hackathon focused on tackling our biggest problems. Because we believe the greatest rewards come from solving the greatest challenges: our climate, our health, our society, our shared future.

This is a call to all problem engineers. Join us and put your skills to work on what truly matters. This year's specific challenges will be announced later, but we can already reveal that they'll centre on energy, AI safety and physical AI.

Join as a team or solo. Teams will consist of 3-4 people, so if you apply individually or as a team of two, we'll match you with other participants.

Come help us prompt what matters. Apply below 👇

Fixathon FAQs

What Is a Fixathon & How Does It Work?

A Fixathon is like a hackathon, but focused on solving real-world challenges that desperately need fixing. In 24 hours, participants collaborate in teams to turn ideas into applicable solutions or working prototypes, using AI and open tools.

Who Can Apply?

Anyone passionate about solving meaningful problems is welcome to apply (as long as you are 18+ years old).

You can apply individually or together as a group. Please note that everyone must send in their own application, even if applying as a team. If you apply alone or as a team of two, we will match you with additional participants to complete your team. Teams will consist of a minimum of 3 and a maximum of 4 people.

Do I Need Coding Skills?

No previous hackathon experience is required, and coding skills are not mandatory. However, having coding experience can be an advantage.

Is There an Age Limit?

Yes, participants must be at least 18 years old. Please don't apply if you're under 18. We'll verify IDs both during the application process and on-site at the event.

What Makes a Great Team & Team Matching?

The best teams combine different skills and perspectives. Diversity in backgrounds, thinking, and experience helps unlock stronger ideas and more impactful solutions.

We carefully review all applications and primarily match teams based on complementary skills, ensuring that every team has a strong mix of people and perspectives. Team matching happens once we've confirmed all participants for the event. We're aiming to inform you about your team by mid/end of August, giving everyone enough time to connect in advance, and optionally coordinate accommodation together if you'd like.

How Do I Know If I Got Selected?

You'll receive an email from us confirming whether you've secured a spot. From there, we'll stay in touch with next steps and more details about team matching, the schedule, logistics, and practical information ahead of the event.
