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. Yet for decades, the tools to manage that variable have been blunt instruments: static meal plans, generic macro calculators, or the constant, manual oversight of a dedicated nutritionist. 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,factoring in metrics like average watts and session importance,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. This creates a feedback loop, moving nutrition from a pre-set prescription to a dynamic component of the training cycle. 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 did not emerge from a generic tech incubator. It is a commercial spin-out from research at Liverpool John Moores University, and its founding team carries deep domain credentials [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]. This pairing of academic research and top-tier practical application is central to the company’s credibility. They are joined by co-founders handling engineering, data science, and behavioral science, the latter a UX research manager from Meta, suggesting an intentional focus on user adherence beyond mere algorithmic output.
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]. This blend of science, elite sport experience, and commercial acumen has proven persuasive to a specific class of investor.
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, a venture firm with a portfolio focused on sports, media, and health. Perhaps more telling are the strategic partners: Sport Republic, an investment group with holdings in football clubs, and individual athletes like Premier League striker Patrick Bamford [Sports Business Journal, Unknown]. This capital signals validation from within the very ecosystem Hexis aims to serve, providing potential avenues for distribution and pilot programs that pure financial VCs could not.

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, which also offer personalized nutrition planning for athletes. 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. This two-sided approach targets both the end-user seeking an edge and the professional who needs to scale their expertise.
Yet, the path from a compelling tool for elite coaches to a sustainable, venture-scale business is not without its questions. The risks here are less about scientific validity and more about commercial execution.
- Market size and willingness to pay. While elite teams may budget for such tools, the broader market of amateur endurance athletes represents a larger opportunity but a more price-sensitive one. 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 platform operates in the realm of performance enhancement, not disease treatment. This places it outside the stringent regulatory pathways of the FDA or EMA, which can be a speed advantage. However, it also means the burden of proof for efficacy rests on published research and user testimonials rather than regulatory approval. The company’s academic roots are an asset here, but peer-reviewed outcomes data will be crucial for long-term credibility.
- The motion from elite to mainstream. Many sports tech companies use elite athletes as a proof-of-concept and marketing vehicle. The harder transition is building a product and go-to-market engine that efficiently reaches the committed amateur. Hexis’s recent funding will likely be deployed to test this motion.
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. The involvement of Sport Republic could open doors in professional football. Another signal will be the publication of clinical or performance studies stemming from its research partnerships, moving its claims from proprietary technology to publicly scrutinized science. Finally, observing how the company evolves its pricing and packaging for the individual athlete segment will reveal its strategy for capturing the broader market.
For the athlete dealing with underperformance, the problem is often framed as one of insufficient talent or inadequate training. But for a growing number of coaches and sports scientists, it is increasingly seen as a fueling problem,a mismatch between energy expenditure and intake that no amount of willpower can overcome. The standard of care today is a patchwork. At the very top, it involves a full-time nutritionist crafting individualized plans and adjusting them daily. For everyone else, it is guesswork, generic advice, or static PDFs that don’t reflect the reality of a dynamic training week. Hexis is attempting to productize that elite-level, dynamic guidance. Its success will depend not on whether the science is sound, but on whether it can build a business around making that science accessible, reliable, and indispensable to the athlete trying to improve, and the coach trying to help them.
