About Bill Simmons

I am the Co-Founder and CEO of Orbit.me. I was formerly the CTO & Co-founder of DataXu. I also held executive product management positions at Roku ($ROKU) the The Trade Desk ($TTD). While at DataXu I founded the OpenRTB Consortium, a coalition of technical leaders across the ad tech industry to create the standard transaction protocol for real-time advertising transactions. The IAB Tech Lab now manages OpenRTB. Previous to getting into advertising technology, I was an aerospace engineer. I worked on 14 space missions, including Atlas Launch Vehicles and the Chandra Space Telescope. I received a Ph.D. from MIT in Course 16: Aeronautics and Astronautics, with an emphasis on combinatorial optimization for complex system design. I\'m also a dad, an angel investor, and a startup advisor.
