They have more than 40 years of experience in the development of computer-driven, model-based trading systems. Together, David and John run the company.  They work together to drive the mission and strategy for Two Sigma, nurture talent and shape the company’s unique culture.

David Siegel, Co-Chairman

David is a computer scientist, entrepreneur, and philanthropist.

Inspired by 2001: A Space Odyssey, David was drawn to computer science at a young age and developed a deep interest in programming. This interest sparked a life-long passion for building intelligent computational systems, reflecting the belief in technology's potential to improve virtually every human endeavor.

After graduating from Princeton, David received a PhD in computer science from the Massachusetts Institute of Technology, where he conducted research at the Artificial Intelligence Laboratory.

David's philanthropic efforts underscore his conviction that education, science, and technology are the keys to a better world. He sits on the board of organizations that promote this conviction, including the MIT Corporation, Cornell Tech, Carnegie Hall, the Scratch Foundation (which he co-founded), and Stanford’s Center on Philanthropy and Civil Society.

In 2017, David was honored by the Academy of Achievement for being a pioneer in technology and investment management.

John Overdeck, Co-Chairman

John began his career at D.E. Shaw & Co, where he rose to Managing Director. While at D. E. Shaw, he directed the firm’s Japanese equity and equity-linked investments and supervised the firm’s London investment management affiliate.  Following D.E. Shaw and before starting Two Sigma, John spent two years at Amazon.com, first serving as Vice President and technical assistant to Amazon.com founder Jeff Bezos. He went on to lead customer relationship management at Amazon.com, directing Amazon’s renowned personalization, community, and targeted marketing features and technology.  He also led critical efforts to make Amazon’s customer technology more scalable.

A lifelong math enthusiast, John won a silver medal for the United States in the 27th International Mathematics Olympiad. He earned a B.S. in Mathematics (with distinction) and a M.S. in Statistics from Stanford University. John currently serves on the Board of Directors of the Hamilton Insurance Group. In addition to his family’s charitable activities, John also serves on the boards of the Robin Hood Foundation, the Institute for Advanced Study and is the acting Chair of the National Museum of Mathematics.

In 2017, John was honored by the Academy of Achievement for being a pioneer in technology and investment management.
