Who we are

We are on a mission to make mental health accessible to everyone. At OpenUp, we support companies, their employees and the families of employees with mental health. Via our OpenUp platform, employees and their families receive direct access to health checks, self-help programs, group sessions and webinars, mindfulness training and a large team of recognized psychologists.

But that's not enough to achieve our mission: We aim to become the number one mental health partner in the whole of Europe.
