Ada Health

Ada is a digital health company created by doctors to improve human health by transforming knowledge into better outcomes.

Ada helps you and your loved ones check symptoms and discover what might be causing them – day or night without an appointment.

Ada was founded in 2011 by Claire Novorol, Daniel Nathrath, and Dr. Martin Hirsch. The company is based in Berlin, with offices in New York, London and Munich.


Ada has developed a powerful AI-based health assessment and care navigation platform that helps users to understand their symptoms, to identify and differentiate conditions with a high degree of medical accuracy, and to navigate safely to the right care, at the right time.


Ada's core system connects medical knowledge with intelligent technology to help all people actively manage their health and medical professionals to deliver effective care, and the company works with leading health providers and organizations to carry out this vision.
