About us.

We work in partnership with Germany's most successful companies and use our industry experience and expertise to develop outstanding practice-oriented training programs for data and AI skills. We empower companies through their employees to master the data and AI revolution. And enable job seekers to acquire the skills they need to enter data and AI professions with confidence.

Who We Are. And why that matters.

StackFuel is Germany's leading provider of data and AI training—and we're proud of it. Over 8,000 graduates, a 93 % completion rate, and government-funded programs that really work.

Our team of experts in product development, content, technology, and mentoring shares a common conviction: In the age of AI, expertise is what matters most.

Our History.

Berlin, 2017. Stefan Berntheisel and Leo Marose founded StackFuel—driven by one conviction: technological skills belong to everyone. What began as a vision has grown into one of Germany’s leading EdTech companies—with clients such as Deutsche Bahn, Mercedes-Benz, and Telefónica.

In 2026, Multiverse, Europe’s only EdTech unicorn, acquired StackFuel. It was a long-anticipated acquisition: to train 100,000 workers in Germany for the AI era. In this way, a Berlin startup has become a European response to a German challenge.
