Hexis

Hexis is a UK-based sports nutrition technology company that has built an AI-powered personalised fuelling platform for athletes. At the core of the product is the company's proprietary Carb Coding™ system, which translates peer-reviewed sports science into real-time, individualised nutrition plans that adapt dynamically to each athlete's training load, workout type, goals, and recovery status — delivered minute-by-minute via a mobile app and a practitioner-facing desktop platform.

The problem Hexis addresses is a fundamental gap in how performance nutrition is delivered at scale. Elite sports nutritionists have long understood that carbohydrate needs vary dramatically depending on the nature of each training session, but translating that knowledge into practical day-to-day guidance for individual athletes requires hours of manual planning per person — time that practitioners simply do not have when supporting large squads. The result is that personalised nutrition support reaches only a small fraction of athletes even on professional teams, while the majority operate on generic plans that fail to account for the unique demands of their schedule.

Hexis automates this process entirely. Integrating with wearables, GPS devices, and training platforms such as TrainingPeaks and Catapult, the system ingests workout data and generates precise carbohydrate and energy recommendations before, during, and after every session. Athletes see clear visual cues indicating whether a meal should be low, medium, or high in carbohydrate; practitioners gain a dashboard covering entire squads. Beta testing with 963 elite athletes — 54% of whom were women — demonstrated that Hexis improved performance and energy levels for 95% of participants, with some female athletes reporting the return of their menstrual cycle after years of underfuelling.

Hexis raised a £1.6 million pre-seed round backed by APEX Capital, Dopamine Sport Ventures, and Sport Republic, and counts Olympic medalists, Tour de France stage winners, and clubs including Southampton FC among its users and angel investors. The company's founding team holds PhDs in sports nutrition, exercise physiology, biostatistics, and data science, and its academic advisory board includes Professor James Morton, former nutritionist to Team Sky and INEOS.
