With studios, a retail arm and a national Lagree instructor certification platform, Jamie Weeks’ Founders Row is backing SculptHouse’s expansion to more major markets
SculptHouse is gearing up for a major expansion, and it just landed the capital to do it.
The woman-founded boutique fitness brand, the first to combine the Lagree Megaformer with interval cardio on a Woodway Curve treadmill, has received an investment from Founders Row, the founder-focused investment firm launched by Jamie Weeks.
Beyond its group classes, SculptHouse operates an activewear and lifestyle arm and a national Lagree instructor certification platform — an interesting hook that sets it apart from the Pilates boom and offers a high-intensity, low-impact experience.
The capital will fuel SculptHouse’s expansion plans, including a real estate push in its native Atlanta, along with South Florida, Charlotte, Dallas, Nashville, and Boston. Several leases and acquisitions are already in the works, SculptHouse said.
“I wasn’t looking for capital for the sake of capital,” SculptHouse founder Katherine Mason said. “I wanted a true partner, someone who understands what it’s like to build something from nothing, who respects the foundation we’ve built and who can help bring structure and clarity to the next phase of growth without changing who we are. Jamie and the Founders Row team bring all of the elements that I was looking for to this partnership.”
SculptHouse currently has two studios in Atlanta and Dallas. Two classes are offered: SculptHouse’s signature CardioSculpt, a 50-minute class that pairs intervals on the Woodway Curve treadmill with strength sequences on the Megaformer for a full-body challenge. There’s also StrengthSculpt, a 50-minute total-body workout performed entirely on the Megaformer.
“Katherine is exactly the kind of founder that Founders Row exists to support,” Founders Row creator Jamie Weeks said. “She’s lived every role in this business, rebuilt it through adversity and created something truly differentiated. This partnership isn’t about a private equity playbook; it’s about backing the founder’s vision with conviction, empathy and a long-term vision for what this brand can become.”
If Jamie Weeks’ name rings a bell, it’s because he’s spent more than a decade in the space and was the former largest franchisee of Orangetheory Fitness and the founder of cold plunge and infrared sauna studio brand SweatHouz.
He launched Founders Row last year as an alternative to traditional models, with hands-on involvement across strategy, operations and growth planning without requiring founders to relinquish majority ownership or control.
“As traditional private equity firms grow even larger, it becomes difficult for them to invest at the earliest stage of a brand’s growth cycle,” he said last year. “This is exactly where the unicorns live — just as Orangetheory and SweatHouz once did.”
While Weeks brings deep fitness and wellness expertise, Founders Row centers on founder quality over sector focus, leaving room for investments beyond fitness.
