Through our AI tracking algorithm, real-time reporting, and data-driven attribution.


WHO WE ARE

We are a team consisting of about 30 people at the moment. Our engineering teams (Tracking & User Experience and AI & Analytics) consist of about four people each. Currently, we are looking for both teams - Frontend for our Tracking & User Experience team and a Database Expert for our AI & Analytics team.

Also, we are remote first - which means that your location doesn't matter to us at all - we believe that you can work from anywhere! Therefore, our employees are located in Germany, Austria, and also in the Netherlands right now. To maintain our great team cohesion, we regularly plan a lot of cool team events to which everyone is invited.
