Company Description

We’re TSG. There’s a good chance you’ve not heard of us yet – we’re just getting going. We’re the people who power gyms, fitness facilities, childcare centers and independent personal trainers in a load of places across the globe (US, Aus, NZ, UK, Japan, France, and Canada, with more to come). We’re bringing together the very best companies in the industry through smart, intentional acquisition. And we’re getting ready to go big. 

In the US, we’ve brought together Mariana Tek, Zingfit, Triib and TrueCoach, to form our Boutique Vertical. There’s over 140 of us in the Boutique team and we’re passionate about fitness, stellar customer support and creating tech that solves problems for busy people. We’re based across the US with offices in DC, Boulder, Louisville and Boston. Our products are already revolutionizing boutique fitness, by automating admin and other tasks for gym owners and trainers, so they can get out of the office and spend more time doing what they love.
