expenseBrain creates success

Our vision

We optimize digital and personal collaboration. The future is automatic and digital.

In this way, you free up your employees' time and improve transparency and efficiency.


We improve the user experience of the business traveler before, during and after the trip. We automate and optimize the business travel process.

We are the answer for all companies looking for a fast, secure and innovative travel process. Together with customers and suppliers, we drive innovation.


For today: We bring your travel management to the cloud and improve your processes. This saves time and costs. Travel capture, approval and verification happen within hours. Manual entries are no longer necessary.

For tomorrow: We are doing away with travel expense reports altogether. Intelligent systems are networked and process the data automatically.
