| Gaston | Gaston is a disruptive platform that aims to revolutionise the way we consume foods for boosting health and wellbeing in UK, US and India markets. Functioning as B2B SaaS platform, it helps food technology platforms (e.g. food apps, table reservation apps, catering companies, etc.) to connect their users’ who have dietary, nutritional,medical-conditions and lifestyle related food restrictions to foods that they can consume safely. We do this by using Artificial Intelligence (AI) and power of data and analysing the ingredients and nutrition information of millions of foods (and recipes) to curate highly personalised suggestive food and recipe recommendations. Our smart algorithms analyse users' pathological (and progressively genetic) profiles to understand foods and (micro)ingredients that can help them live healthier longer lives. | $327K | Pre-Seed | Jan 04, 2022 | https://www.gogaston.io |
| Gaston Ai | Food is the most powerful — yet underused — lever in preventing and managing chronic disease. Over 1 billion people already live with non-communicable diseases (NCDs) like diabetes, cardiovascular disease, autoimmune conditions, etc. while billions more are unknowingly at risk. Despite clear evidence linking diet to health, today’s food systemremains generic, reactive, and disconnected from individual biology.Gaston AI is changing that. We are a multi-award winning HealthTech with presence in Europe and USA. We’ve built a precision nutrition platform that uses AI, biomarkers, and clinical nutrition science to deliver real-time, personalised food decisions — at scale. Beyond managing allergies or restrictions, our system:Recommends foods based on metabolic markers, inflammation, and insulin sensitivity Supports those with diagnosed conditions (e.g., Type 2 diabetes, celiac) Predicts and modulates future disease risk using digital twins and longitudinal data Suggests phytonutrient-rich food patterns to optimise gene expression and long-term healthDelivered via API integrations, AR-powered grocery scanning, and a medical-grade claims engine across 1,000+ use cases, Gaston AI empowers individuals to choose smarter, while enabling retailers and brands to personalise offerings, drive loyalty, and lead in the food-as-medicine revolution.We’re building a future where food isn’t guesswork — it’s precision healthcare. | $338.2K | Pre-Seed | Jan 04, 2022 | https://www.gogaston.io |
