Tobias is a co-founder of GmbH. Since 2009, him and Sam have been developing and optimizing new slack designs and then producing their own slackline-sets for indoor and outdoor use. Not only do they bring their latest slackline technology to the market, they also teach sport instructors, physiotherapists, kids and teens how to walk the line.  A key component in this instruction is training concentration in the sport.
