We are Team heat it™

How everything began...

The brilliant idea originally came about in 2017 during a student competition. Fed up with mosquito bites, we tried out the treatment using concentrated heat and were immediately convinced by the principle, but not by the available products. Too clunky, never with us and unadaptable! So we decided to take the development into our own hands.

On an itch-free mission

Insect bites can be treated effectively with heat, but sting 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.

Own development and production

Made in Germany

Since 2019, we are a certified medical device manufacturer with our own development and production in the Technologiefabrik of Karlsruhe. In the meantime, more than 15 clever minds are working in various departments of our medtech start-up. From procurement, to production, to shipping: we don't leave anything by chance.

In the summer of 2019, we were able to convince almost 2,000 people to support us in crowdfunding on Startnext. In parallel, we were able to complete the German certification as a medical device manufacturer.

After founding the company, we found our place at Cyberlab Karlsruhe. This startup accelerator offered us the perfect opportunity to put the final touches on heat it™ and our company.

The initial idea came about as part of a student competition at the Karlsruhe Institute of Technology. This was quickly followed by the first prototypes, further competitions and the first patent applications.
