CALIMA Safety GmbH was founded in April 2021 by Tim Hautkappe, Katharina Hochmuth and Michael Zerbin. When CALIMA was founded, the founders already had experience with digital safety technologies. Since 2014, they have been using the "KommGutHeim" app to make women feel safer when they are out and about.


The idea for CALIMA was born out of the increasing demand from companies as to whether this app can also be used for the safety of their employees. The focus is on the target group of the 8.5 million lone workers in Germany.

Lone working refers to activities that take place outside the call and sight range of other people. In emergency situations such as accidents, attacks or medical emergencies, employees are dependent on timely assistance.

Many companies have struggled to find an effective and affordable solution to ensure the emergency chain. CALIMA has closed this gap with a digital, intuitive and cost-effective emergency system.
