Unlearn.AI was founded in 2017 by Jonathan Walsh, Aaron Smith, and Charles Fisher. The company is headquartered in San Francisco, California, with an office in Cambridge, MA.


Unlearn.AI is the only company creating TwinRCTs™, a randomized trial that uses machine learning and historical data to achieve a higher probability of success with a smaller number of patients.

Unlearn won approval from the European Medicines Agency (EMA) in September 2022 for using its AI-driven approach for conducting smaller and quicker clinical trials and struck several multi-million dollar deals with pharmaceutical companies, including Merck, Darmstadt, among others.
