Zoe is a Boston and London-based company which builds software for tracking individuals' nutrition response patterns, as well as a mobile application for tracking COVID-19 symptoms.

Nutrition response tracking

Zoe working with scientists and thousands of volunteers – combining large-scale data and machine learning to predict personal nutritional responses to any meal. The company says it is working with some of the world’s leading scientists from academic centers including Harvard, Lund (Sweden), Massachusetts General Hospital, Oxford (UK), King’s College London (UK), Tufts and Stanford.

The company uses blood tests and stick-on glucose monitors (originally developed for people with diabetes) to see how the levels of chemicals such as fat, insulin and sugar change in each person’s bloodstream after eating a set of identical standardized foods and their own regular meals. We also gather data on activity, sleep, hunger and gut bacteria (microbiome).

The company intends to use this data to build machine learning models to figure out what’s going on when people eat specific foods and predict with high accuracy how they’ll respond to any meal.

COVID-19 Response

In response to the COVID-19 pandemic, Zoe developed and launched a COVID symptom tracker, which was created by doctors and scientists at Massachusetts General Hospital, the Harvard T.H. Chan School of Public Health, King's College London and Stanford University School of Medicine.

Zoe publishes COVID-19 symptom data for the United Kingdom on its website.The company announced on March 28, 2020 that it had gathered data from over 1 million volunteer contributors.
