Our Company

We’re here to get the world climbing, again.

CLMBR is reintroducing you to the activity that's always been part of every human life, to unlock the potential that's been waiting within you.


How It Started

In 2018, we set out to revolutionize the vertical climbing machine. Bringing together an innovative, vertical climbing machine design with an engaging platform of world-class fitness instructors and strong community engagement.

A New Concept In Fitness

CLMBR changed the way vertical climbing machines had been approached. Re-engineering the machine from the ground up allowed for greater freedom of the users' movement while creating additional space for a touch display that could deliver interactive content, games and much more to every user.
