From 2019 to 2024, I was one of the Co-Founder and CEO of epap, a startup in Germany.

epap leverages receipts to connect brands with shoppers, providing tech-driven insights from 200k+ retail stores and restaurants across Germany. Our app has enabled 100k+ users to track purchases and manage accounting, collecting millions of receipts. This data enabled us as a company to deliver precise and immediate shopper insights to our clients.

I was responsible for the iOS- and Android app designs, as well as mobile implementation using Flutter. The app is only available in the German market and currently has around 4000 ratings averaging 4.6 stars.
