Felix Häberle

About

My name is Felix Häberle. I'm based in Berlin, building AI agents. I like building products where thoughtful design, technical depth, and a real sense for people come together.

Before that, I spent more than ten years designing and engineering products in startups, most recently at inlang, where we built developer tools for internationalization (i18n) and a new kind of version control system called lix. Open source has been at the heart of that work, with a special focus on accessibility and performance.

I'm European by heart. I support EU Inc, and I'm proud of what Europe stands for: openness, diversity and the idea that we are stronger together.

Outside of work you'll find me in nature and doing sports: gym, swimming and biking.

1
Research and Ideation

Focusing on what the user needs,
not the product.

Good ideas can be hard and are often based on a good analysis of the challenge. They can be wild & visual or calm & concept based. At the end, the resulting design should be well tested and pay up to the user needs. To achieve this, I work with an interdisciplinary toolchain.

The creative part

A structured way to create magic,
without magic.

I learned to understand how people think and to care about environmental and social challenges and find the best solution for it. Creative outcome is no magic moment — it’s about caring for the users. That’s my way to think about how to approach creativity: be an inclusive provider.

Technical background

Rooted in engineering,
focused on the product as a whole.

More than ten years of building digital products taught me the whole craft: design, engineering and everything it takes to ship. Today AI runs through all of it. I build products around AI agents, work with AI every day, and stay involved in open source along the way.
