Company
Mantis
Digital Twins of humans
We build digital twins of humans by combining large language models with physics-based simulations. Our product takes rare and hard-to-access human behavior data and turns it into predictive models. These models help researchers and companies understand and anticipate complex human behaviors that current data methods miss.
We live in New York City, and plan for the company to remain based here after YC.
We're based in New York because that's where our team and initial network are, and this location gives us close access to partners and collaborators interested in advanced human behavior modeling.
