David Renton, Former COO of Zwift, Joins Nix Biosensors

October 17, 2022

As Interim COO and CTO, Renton will help launch Nix’s first product, a sweat-analyzing biosensor

BOSTON, MASS. — OCTOBER 17, 2022/ENDURANCE SPORTSWIRE/ – David Renton, former COO of Zwift, has joined Nix Biosensors as Interim Chief Operations Officer and Chief Technology Officer. Renton brings more than two decades of leadership in technology to Nix, whose first consumer product, a small patch that analyzes athletes’ sweat in real-time to provide personalized hydration guidance, is launching in Q4 2022.

During his 5+ years at Zwift, Renton presided over a 10x increase in users and helped secure more than $770 million in funding. More broadly, Renton scaled Zwift’s organization and product to meet exceptional demand by integrating its game, events, and hardware touchpoints. He also helped advanced Zwift’s esports offering, which has grown to become a substantial discipline within cycling. This led to banner events like the UCI Esports World Championships, now in its third year; the Tour de France Virtual, held during the pandemic when the TdF was canceled for the second time in over 100 years; and the eventual launch of the real-world Tour de France Femmes avec Zwift.

“So many industries are evolving right now, especially sports and fitness,” says Renton. “I believe that one of the biggest and most exciting areas of this evolution is in biometric data. For years, the status quo of wearables has been activity trackers worn on your wrist. The next generation of fitness technology is biosensors – devices that provide a new class of data and level of personalization never seen before in consumer health and fitness technology. I believe that Nix is leading this new wave of innovation — and providing directly actionable data – and that’s why I’m so excited to be a part of their amazing team.”

Nix’s first product, the Hydration Biosensor, is a small patch that analyzes athletes’ sweat in real-time, telling them when, what, and how much to drink, quantifying fluid and electrolyte losses, and more. Nix plans to launch additional biosensors, designed specifically for team sports, military and labor applications, in 2023.

Other recent hires include Pratik Patel, Nix’s Director of Human Performance and former Director of Performance Nutrition and Assistant Strength & Conditioning Coach for the New York Giants; Inga Stenta, Nix’s Chief Marketing Officer and former Head of US Marketing at Reebok, and Tom Fowler, one of Nix’s many advisors and former president of Polar.
