About us

The guys behind tense-it are Jonathan, Michael and Daniel. Three athletes, technicians and visionaries. The best conditions to revolutionize and simplify the Slackline sport.
After various problems at setting up a Slackline, Jonathan decides to create a completely new tensioning system for his diploma thesis together with Daniel. Michael has always been enthusiastic about the entrepreneurship and he saw the opportunity to improve the product even further to found a startup later.
For a year now, the guys have already intensively dealt with technology, ergonomics and design – with the goal of making their tensioning system available to all slackliners worldwide.
