Company
An AI startup out of the University of Tokyo, researching and developing digital twins of people and society.
Company Overview
Message from the CEO
Takehiro Takayanagi
CEO / Researcher
Simulacra is an AI startup born out of the Izumi Laboratory at the University of Tokyo. We research and develop foundation models for digital twins that reproduce how people think and behave. By modeling an individual's decision-making patterns and scaling that up to organizations and society, we aim to make it possible to simulate any option before acting on it. Our mission is to turn decision-making from something that rests on intuition and experience into something you can test and verify.
Team
Our members come from the University of Tokyo and other research institutions, bringing together expertise in AI, social simulation, and data science.
