How Hytro Built in Pro Sport, Reached NASA & SpaceX and Chose Not to Go DTC Too Early with Co-Founder & CEO Raj Thiruchelvarajah
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.
In this episode, you will hear:
• Why Hytro first launched in the wrong market and what that taught Raj about go-to-market strategy
• How blood flow restriction became scalable through wearable product design
• Why pro sport became the ideal proving ground for credibility, revenue and advocacy
• How NASA and SpaceX became part of the Hytro story
• Why coaches and athletes investing in the business became such a powerful signal
• Why not every business should chase DTC first, even if that looks like the obvious route
• How founders should think about saying no, protecting focus and choosing the right roadmap
• Why founder life, fatherhood and ambition can create a brutal but meaningful season of life
• How Raj thinks about moving from startup chaos to scale-up clarity
• What Hytro is building next as it prepares for a future consumer play
