About
ZOE is a health science and consumer technology company headquartered in London, United Kingdom, co-founded by Professor Tim Spector (King's College London epidemiologist and author), Jonathan Wolf, and others. The company emerged from the PREDICT studies — the world's largest nutritional science research program, which enrolled over 1,000 participants to study how different individuals respond to the same foods based on their gut microbiome, blood fat response, blood sugar response, sleep, and exercise patterns. The research established that personalized nutrition — rather than one-size-fits-all dietary guidelines — is scientifically grounded, as the same meal can produce dramatically different metabolic responses in different people.
Epic holds over 42% of U.S. acute care hospital EHR market share and is embedding AI across 150+ clinical workflows for 2026, while facing antitrust scrutiny.
