Therabody

The Spark

Jason Wersland's journey to founding Therabody began with a motorcycle accident while he was studying to become a chiropractor. Desperate for pain relief and searching for solutions to ease his arm injury, he conducted a late-night experiment with a Makita jigsaw—discovering that the percussive massage from the power tool actually helped reduce pain and increase his range of motion.

Building the First Version

With his discovery in hand, Jason didn't wait for perfect conditions or investors. He began MacGyvering hundreds more units, initially improvising add-ons from whatever materials he had: fence posts and cat toys served as early percussion heads. This scrappy, bootstrapped approach to manufacturing showed early product-market fit wasn't about polish—it was about solving a real problem.

Finding the First Customers

Jason's first customers were his own chiropractor patients. The device worked as well on them as it did on him, creating natural word-of-mouth interest. Instead of pursuing traditional marketing channels, he relied on the product's effectiveness and organic recommendations from satisfied users.

What Worked

The turning point came through endorsements from top athletes and celebrities. As influential figures adopted and promoted the Theragun (the product's eventual name), the brand gained credibility and reach far beyond his patient base. These endorsements validated the product and accelerated growth dramatically.

Where They Are Now

Therabody evolved from a garage experiment into a full wellness brand generating revenue in the hundreds of millions of dollars. What started as a jury-rigged solution to one man's pain became a category-defining product used by professional athletes, celebrities, and millions of consumers worldwide.
