Fixing the Paris Agreement

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.

This Fixathon takes place at Norrsken House Barcelona before and during Norrsken Impact/Week, from October 13-15. Participants will kick off the Fixathon in the late afternoon on October 13, spend 24 hours developing their solutions, and wrap up together in the evening of October 14. If you'd like, you can work through the night during the 24-hour sprint (there will be a few couches), but we encourage you to book a hotel for that night too, to get some hours of sleep and to store your luggage.

On October 15, participants can explore Impact/Week, and a few selected teams will have the opportunity to present their solutions during a live demo (so make sure to stay that day too). The full agenda and activities will be shared with selected participants closer to the event. Please be aware that everything will be in person, so make sure to block your calendar from October 13 through October 15.

Impact/Week is Norrsken's two-day flagship conference happening October 14-15, 2026, at Norrsken House Barcelona. It gathers a carefully curated audience of the world's foremost founders, funders, thinkers, and doers accelerating solutions for people and planet.

The Fixathon will focus on a climate-related challenge, centered around the Paris Agreement. We'll provide more details on the challenge to selected participants closer to the event. Please note that you and your team will have to come up with your own original idea or solution to tackle it within the 24 hours.

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.

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

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.

We're accepting applicants on a rolling basis, so spots are filled first come, first served. Apply early, as there's no guarantee a spot will still be available if you wait. We are doing our best to review all applications, but please bear with us if this takes some time. Every selected participant will receive a heads-up by mid/late August at the latest, so there's still enough time to book your flights, accommodation, etc.

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.

In addition to the Fixathon program and activities, all participants will receive full access to Norrsken Impact/Week, including its events and networking opportunities. A few selected teams will also be invited to present their solutions in a live demo on October 15. The rest remains a secret for now.

If you're traveling from outside Barcelona, we'll reimburse up to 400 EUR per person for travel to, and accommodation in, Barcelona for the Fixathon, based on valid receipts and actual expenses incurred. You're responsible for booking your own flights/trains and accommodation. Reimbursement will be processed after the event, and only for participants who attend the entire Fixathon in person and submit valid receipts related to the event.

We'll provide a guide on traveling to Barcelona for all chosen participants in August. This will include recommendations for accommodation as well as things to do (and avoid) during your stay. We're happy to share suggestions, but you'll be responsible for booking and coordinating your own travel and accommodation.

You are responsible for your own health and travel insurance. Norrsken and the Fixathon organizers do not provide insurance for participants to, from, and during their trip in Barcelona, so please make sure you're covered before you travel.

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.
