Klak - the story

We began developing Klak in 2015. After building the first working prototypes, Andreas wrote his Bachelorthesis about the case. In the same year, Tim joined the team and we got Klak patented. 2019 is the year for Klak - Klak is ready for mass production, we just need your support!

Its your turn!
