Our take
The digital healthcare market is one of the fastest-growing on the planet, and is expected to be worth over $400 billion by 2027. With key drivers including increasing use of mobile platforms, rapidly changing healthcare infrastructure and government initiatives across the globe, this is a market blossoming with opportunity.
Caspar Health is looking to make the most of this. Founded in 2016, the platform enables recovering patients to access rehabilitation services on-demand, such as physiotherapy, sports therapy and even psychosomatic medicine. Setting out to solve the traditional problems with aftercare - things like specialist shortages and location constraints - Caspar Health looks like a highly disruptive prospect.
The company's impressive early metrics - including one bi-annual growth figure topping 300% - have garnered massive investor interest. Using funding won across multiple rounds, Caspar Health wants to expand its existing set of clinical partners, with a goal of supporting all rehabilitation clinics throughout Germany. In the future, its ambitions may go much further.
