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. 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 Challenge: Unlocking Data-Driven Decisions

Employees at all levels and across all business units and functions make decisions that have a direct impact on H&M's success. In this hackathon, we will explore how H&M could make trustworthy, fast-access data a reality across the business. These capabilities could be used to power decision-support apps that help people at every level make better, faster calls.

The capability layer

We will explore how to make data trustworthy, discoverable, and fast to act on, improving correctness and traceability, access and discoverability, performance, visualization, and the interfaces that let people and applications use the data. 

The app layer

Imagine what we could do with this capability! We want your creative thinking to help show what's possible: exploring sales in real time, comparing performance against last year, moving between markets, categories, channels, sections and brands, and drilling 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.

Capability teams: Explore how to use game-changing tech to build game-changing capabilities that unlock game-changing applications. Needed expertise: software engineering and understanding of the relevant operations and infrastructure in your organization. 

App teams: Explore which game-changing applications could be built on your game-changing capability. Needed expertise: creative thinking, application development, product design and understanding of the user goals that this new capability could greatly help

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.

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.
