We are advancing AI to power the future of medicine.

At Unlearn, our purpose is to advance artificial intelligence (AI) to eliminate trial and error in medicine. We use AI to simulate potential health outcomes for individual patients. Today, we are reimagining the randomized control trial (RCT) for the 21st century through AI-powered clinical trials or TwinRCT. A TwinRCT allows more trial patients to receive the experimental treatment, reaches full enrollment faster and put patients first. Unlearn’s innovative work in AI today will reinvent how AI is applied in medicine tomorrow—and we have a top secret plan for how to get there. We won’t be able to achieve this mission just by applying technologies created by others; the future must be invented.

Unlearn is a technology company, not a biotech company. We use computers, not pipettes. We make and use software, we don’t discover or make drugs. We believe that AI will define the future of medicine, and we aren’t deterred by naysayers or skeptics. 

We come from a variety of backgrounds ranging from machine learning to marketing—but regardless of where we come from, Unlearners share some common traits:

>> Unlearners are ambitious; we aren’t intimidated by big, challenging goals. 
>> Unlearners are disciplined experimenters; we break down our big goals into smaller chunks and meet as often as necessary to track our velocity and iterate quickly. 
>> Unlearners are gritty; we never give up, setbacks just make us try harder.
>> Unlearners are receptive to new ideas; in fact, we hate being stuck with the status quo. 
>> Unlearners are storytellers; sharing information with each other and with the world is super important, too important to be boring.  And, last but not least,
>> Unlearners are team-oriented; we put the mission first, the company second, the team third, and individuals last.

Founded in 2017 by a team of world-class machine learning scientists, we have raised venture capital from top tier investors such as Insight Partners, Radical Ventures, 8VC, DCVC, and DCVC Bio. We completed our $50 million Series B in April 2022. We are headquartered in San Francisco, CA and have an additional office in Boston, MA.
