Our mission since 2018

Insect bites can be treated effectively with heat, but insect bite healers must also be available in a "smart" way. With this incentive, our 4 founders began to develop an innovative medical product while still studying engineering. Now we are a dynamic start-up from Karlsruhe, Germany with our own development and production.
