I'm a founder, product engineer and community builder.

Currently building Attacal : AI agents that attack your app every day and open a pull request for every hole they find, so you never have to think about security again.

a little background

I started a YouTube channel at 10 with Minecraft mod tutorials and tech reviews. At 14 I founded a web dev and video agency that made €20k+ while I was still in high school. Later I studied computer science at CODE University and did ML at Stanford .

Next to uni, I automated the finances of a marketing agency and tried out lots of my own startup ideas. With we built AI agents and a data pipeline that analyzed 1.2M+ TikTok and Instagram videos for Nike and Mastercard. Other ideas became voice agents for car dealerships, a learning app that combines mind maps and flashcards and an AI that plans group vacations.

Most recently, I built and shipped an at SF Consumer Lab in two weeks and made $4k in revenue within four weeks of starting.

YFN

At 16 I ran a podcast asking founders where they failed and met other 16 year olds on LinkedIn. Together we started the Young Founders Network .

In three years I scaled the team from 5 to 100+ volunteers. Today it's Germany's largest community for founders under 25. We have 2,200+ members and have raised €350k+ for entrepreneurial education.
