What to expect?

We need you to build systems for scalable and innovative solutions with Caspar!

Caspar-Health was founded in 2016 to revolutionize the world of therapies. Currently access to medical therapies (i.e., prevention or rehabilitation) is restricted, and patients often do not get the best possible treatment for their recovery. By using the Caspar-Health App, we allow patients to overcome the limited access to temporal and on-site therapy and enable them to exercise anytime and anywhere.

With Caspar, therapists create and share therapy plans with their patients, and both parties interact with each other remotely. Caspar-Health works with the most valued medical facilities in Germany. We are a leader among B2B2C tele-therapy platforms.
