System1 was founded in Venice, CA with a simple mission - use technology to make advertising better and safer, while respecting consumer privacy.

Our inspiration comes from groundbreaking prospect theory research by Nobel laureate Daniel Kahneman and his partner Amos Tversky. Their findings distinguish between two modes of thought: System 2, which is slower and more deliberate and System 1, which is fast, automatic and intuitive.

System1 is led by a team of passionate and experienced entrepreneurs who have built multiple billion dollar companies.

Since our founding, we have assembled an incredible group of data scientists and engineers dedicated to our mission, raised significant funding, made several strategic acquisitions, and expanded our offices around the world. And we are just getting started.
