All are welcome to join us! Everyone can make an impact here — no matter your role, background, or technical experience, this hackathon thrives on diverse competencies. We need your ideas, your domain expertise, and your perspective.

Through the Kick-Off, team collaboration and a full Hack Day, teams with a mix of skills and backgrounds will explore what's possible with AI and other game-changing capabilities. You'll get to push boundaries, test new approaches, and discover new ways of working. It's about experimenting, learning, and having fun while doing it.

The best teams will present their solutions at the Grand Finale — where the strongest ideas have the opportunity to move forward beyond the hackathon.

The Challenge

Employees at all levels and across all business units and functions make decisions that have a direct impact on H&M's success. But too often, the data they need to make a well-informed decision is not trustworthy, hard to access, or too slow to act on.

In this hackathon, we're exploring how that can be fixed by enhancing H&M's data analytics capability and demonstrating new decision-support apps that can be built on top of it.

The capability layer
Having data isn't enough. We need to be able to trust it, understand it, find it, access it in time, and act on it fast.

That means improving things like correctness and traceability, access and discoverability, performance, visualization, and the interfaces that allow people and applications to use the data.

We won't solve everything at once. Instead, teams will tackle sharp, concrete challenges that move the overall capability forward.

The app layer
Once that capability exists, what becomes possible?

Imagine being able to explore sales in real time, compare performance against last year, move between markets, categories, channels, sections and brands — and drill all the way down to a single article.

The goal is to explore what decision-support could look like when the right data is available instantly and the experience adapts to how different people at H&M actually work.

How this will work
Some teams will work on the capability layer. Others will work on the app layer — both running in parallel.

Capability teams - will crack real, hard technical challenges — different teams taking on different pieces of what makes the capability work.

App teams - will have full creative freedom to turn those capabilities into useful, innovative solutions that create real value for H&M.

Two layers, one shared goal: by the end of the hackathon, we want a stronger capability and a compelling vision for everything it makes possible.

Why Join?

There is no better way to grow both professionally and personally than through hackathons. Connect with colleagues, gain hands-on experience with AI and other game-changing technologies, and explore new ideas in a creative, collaborative, and supportive environment.

This is your opportunity to step outside your everyday work, combine different perspectives, experiment with new approaches, and see what you can build together.

We want this hackathon to be one of the most rewarding things you do this year!

Showcase Your Solution

The strongest teams will get the opportunity to present their solutions at the Grand Finale in front of key decision makers at H&M — all eager to see what you've built and what potential your idea could have beyond the hackathon.

All Are Welcome

Everyone who is eager to learn, explore, and contribute is welcome to apply!

You don't need to be a developer or an AI expert to participate. Great solutions come from combining different skills, experiences, and perspectives. Whether you bring technical expertise, business knowledge, creativity, customer insight, or domain experience — you have something valuable to contribute.

Teams

Teams of 4–5 will be assembled by the organizers, with skills, experiences, and domain expertise in mind to create the best possible mix.

Each team will work together throughout the hackathon to explore the challenge, develop an idea, and turn it into a working prototype.
