For an elite athlete, a nutrition plan is not a static document. It is a dynamic variable, as responsive to a morning’s training intensity as it is to a night’s sleep. Hexis, a London-based startup founded in 2018, is betting that the gap between a plan and a real-time, adaptive fueling strategy is a software problem. Its answer is an AI-driven platform called Carb Coding™, which aims to translate complex sports science into a live, personalized fuel map for athletes and the coaches who guide them [Perplexity Sonar Pro Brief, Unknown].
The wedge of Carb Coding™
The company’s core intellectual property is a system it calls Carb Coding™. The concept is to algorithmically link an athlete’s daily carbohydrate needs directly to the planned intensity and duration of their training sessions. By integrating with platforms like TrainingPeaks, Hexis analyzes upcoming workouts to generate day-by-day and even meal-level carbohydrate targets [joinbasecamp.com, Unknown]. After a session, the system updates its recommendations based on what was actually completed. For coaches managing dozens of athletes, the promise is a scalable way to provide a level of nutritional precision that was previously reserved for Olympic programs with full-time staff.
A founding team forged in academia and high performance
Hexis is a commercial spin-out from research at Liverpool John Moores University [Liverpool John Moores University, October 2021]. The scientific backbone is provided by Co-founder and CEO David Dunne, a sports scientist with a PhD in nutrition and behavior change, and Co-founder Sam Impey, an exercise physiologist who, until recently, served as the lead nutritionist for British Cycling [Sports Business Journal, May 2024]. They are joined by co-founders handling engineering, data science, and behavioral science, the latter a UX research manager from Meta. The company’s board has also attracted seasoned industry figures, including Stephen Moon, the former CEO of sports nutrition giant Science in Sport [Tech.eu, 2024].
Strategic capital from the sports ecosystem
Hexis’s funding history reflects a deliberate courtship of investors who bring more than just capital. The company has raised an estimated $3.06 million across several seed-stage rounds [Company-check style data aggregators, Unknown]. The lead investor is Apex Capital. Strategic partners include Sport Republic, an investment group with holdings in football clubs, and individual athletes like Premier League striker Patrick Bamford [Sports Business Journal, Unknown].
| Metric | Value |

The competitive and commercial landscape
Hexis operates in a niche but growing segment of digital health aimed at performance optimization. Its direct competitors include platforms like Fuelin and MAVR. The startup’s differentiation rests on the specificity of its Carb Coding™ algorithm and its strong academic pedigree. The business model is a SaaS subscription, with a mobile app for individual athletes and a web-based dashboard for coaches to manage entire teams.
- Market size and willingness to pay. Hexis must prove that its value proposition justifies a recurring subscription against a sea of free macro calculators and static planning apps.
- Clinical validation versus performance claims. The burden of proof for efficacy rests on published research and user testimonials rather than regulatory approval.
- The motion from elite to mainstream. Hexis’s recent funding will likely be deployed to test the motion of building a product and go-to-market engine that efficiently reaches the committed amateur.
The next twelve months
With its latest seed round closed, Hexis is positioned to move from a promising research project to a commercial entity. Key milestones to watch will be named enterprise customer deployments, particularly with professional sports teams or collegiate athletic programs. Another signal will be the publication of clinical or performance studies stemming from its research partnerships. Finally, observing how the company evolves its pricing and packaging for the individual athlete segment will reveal its strategy for capturing the broader market.
