About us

HelloBetter was founded under the name GET.ON Institut für Online Gesundheitstrainings GmbH by internationally recognized researchers and psychologists in 2015. In more than 30 randomized-controlled studies, HelloBetter has developed and evaluated 10 online programs from eight specific problem areas in cooperation with Leuphana University, Friedrich-Alexander University Erlangen-Nuremberg, the Free University of Amsterdam, Harvard University and other partners. These programs serve both the prevention and treatment of classic mental illnesses such as depression, anxiety or panic disorders, but also cover topics such as vaginismus or chronic pain. This gives HelloBetter the broadest study base of all providers.

In the meantime, six therapy programs from HelloBetter have been approved by the German Federal Institute for Drugs and Medical Devices (BfArM) as digital health applications and are available free of charge on prescription for all adults with health insurance in Germany. The work of the expert team has been published in international journals (including The Journal of the American Medical Association) and recognized with various awards (including, Wilhelm Exner Award in Psychology 2016, EFPA Comenius Award 2017, Digital Health Award 2018, EU Compass Good Practice 2018 in Mental Health).

The company is based in Berlin and Hamburg and employs more than 130 people.
