Supplement brand Ten Percent Club, has become one of the most trusted supplement brands among professional athletes with over 3,000 athletes regularly using their products. Following a successful £400k seed raise, the brand now forecasts a 300% YOY growth from 2025-26, with that growth rate increasing by the day.
The funding follows a period of rapid adoption within professional sport, supported by a strategic partnership with leading boxing promoter Matchroom Boxing. Matchroom Chairman Eddie Hearn has described the company as “the most sought-after supplement brand in professional sport,” highlighting its growing presence across the sports industry.
TenPercent Club reports that its products are now used by over 3,000 professional athletes across disciplines including boxing, football, athletics, and endurance sport. All products are accredited as safe for elite competition by WeTestYouTrust, addressing one of the most critical requirements for athletes competing under strict anti-doping regulations.
The seed investment has been deployed into product innovation, including a new electrolytes range designed for high-performance training and recovery, as well as marketing initiatives aimed at strengthening the brand’s footprint in professional sport. The company has also secured a wholesale distribution network, placing products with a major UK retailer while expanding global direct-to-consumer sales.
As part of the funding round, the company has formed a new executive board to support international growth and future Series A fundraising. The leadership team brings experience in scaling technology, marketing, and international businesses to support expansion into new sporting markets.
Founder and CEO Luke O’Reilly said: “Elite athletes require absolute confidence in the safety and effectiveness of their supplementation. Our growth has been driven by trust within professional sport, and this funding enables us to scale that trust globally while continuing to innovate for performance.”
With increasing demand from teams, athletes, and sports organisations, Ten Percent Club plans to deepen partnerships across professional sport while expanding retail presence and international distribution throughout 2026.
“To go from building this business in my bedroom three years ago to earning the trust of over 3,000 professional athletes is something I’m incredibly proud of. It shows what’s possible when you focus relentlessly on quality and trust.”
