Our Co-Founders

Two Sigma was co-founded by a computer scientist and mathematician who understood the potential of bringing technology and data to investment management.

David Siegel

Co-Founder, Two Sigma

John Overdeck

Co-Founder, Two Sigma

David Siegel

Co-Founder, Two Sigma

David is a computer scientist, entrepreneur, and philanthropist. He co-founded Two Sigma, where he currently serves as Co-Chairman.

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.

In 2001, he co-founded Two Sigma on the belief that innovative technology and data science could help discover value in the world’s data. Today, Two Sigma, through its use of algorithms and with its unique culture, drives transformations in many industries including investment management and insurance.

David’s philanthropic efforts underscore his conviction that education, science, and technology are the keys to a better world. In keeping with this vision, he founded Siegel Family Endowment in 2011 to support organizations and leaders that will understand and shape the impact of technology on society. David devotes significant time and energy to actively engaging with this work. He is the Chairman of the Board of Overseers at Cornell Tech, a board member of Carnegie Hall, and of the Robin Hood Learning + Tech Fund. After co-founding the board of New York City FIRST, he furthered his commitment to the organization by joining the national FIRST board. David’s service also includes roles on the Global Advisory Board of Khan Academy, the Advisory Board for Stanford’s Center on Philanthropy and Civil Society, and the Advisory Council for Princeton’s Center on Information Technology Policy.

In 2014, David co-founded the Scratch Foundation to support Scratch, a block-based programming language and online community for kids that helps young people learn to think creatively, reason systematically, and work collaboratively — essential skills for life in the 21st century.

As a member of the MIT Corporation, David has the pleasure of serving on the Visiting Committee for the Media Lab, Electrical Engineering and Computer Science, and Center for Brains, Minds, and Machines, as well as with the advisory group for the Task Force on the Work of the Future. He is Founding Chair of the advisory board for MIT Quest, an initiative to discover the foundations of human intelligence and drive the development of technological tools that can positively influence society.  David also sits on the Board of Directors of the Hamilton Insurance Group.

John Overdeck

Co-Founder, Two Sigma

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.

As President of Overdeck Family Foundation, John’s philanthropy is focused on enhancing education to improve academic and socioemotional outcomes for children across the country. In addition to supporting his foundation, John also serves on the boards of the Robin Hood Foundation, the Institute for Advanced Study and is the Chair of the National Museum of Mathematics. He also serves on the Board of Directors of the Hamilton Insurance Group.

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

A history of invention

Since 2001, we’ve searched for ways that data and technology can make us better at what we do. We never stop researching and developing.
