What do you do when your product is scientifically strong, commercially promising… but the mass market won’t understand what it is?

In this episode of Building The Brand, James Burtt sits down with Raj Thiruchelvarajah, co-founder and CEO of Hytro, to unpack how a startup in performance wearables built credibility in elite sport, got product into NASA and SpaceX missions and made the unusual decision to avoid direct-to-consumer too early.

Raj explains how Hytro pioneered wearable blood flow restriction technology, why the business originally started in the wrong market, and how the team realised that pro sport was not just a niche audience but the perfect proving ground. He shares how coaches became one of the company’s biggest growth levers, why athletes and practitioners started investing in the business and how the right kind of advocacy can matter more than pure science-backed data.
