About us

Do you want to work for one of the leading Digital Health Scaleups in Germany and Europe?

XO Life is developing the meta platform brite designed for patients, healthcare representatives and pharmaceutical companies to interact regarding everyday care. Currently, patients mainly consult platforms like Google, Facebook, and Instagram for information search and social exchange due to the lack of a dedicated, highly engaging health platform.

Our mission: Our brite platform is there to enable all pharma companies but also healthcare institutes to offer their patients a state-of-the-art digital product or therapy companion. This all-in-one platform eliminates the need for patients to download a new app for every new drug or treatment, but to have a super health app for self management.

XO Life is recognized as a leading Digital Health Scaleup in Germany and Europe and a top tech newcomer by the German Federal Ministry of Economics and Technology. We work with 30+ pharma manufacturers, spanning from market leaders, SMEs, and RX, OTC, and Medical Device manufacturers across over 30 indications. Building on this success, we're also expanding the platform internationally.

If this sounds exciting to you and you want to be part of this great vision, then apply to join us!
