Sebastian FischerFounder and CEO
I am the cofounder & CEO of Wardstone, a space defense company building satellites to defend the U.S. and its allies from hypersonic and ballistic missiles. I have 10+ years of engineering and product experience in satellites, drones, and self-driving cars. I held leadership roles at Amazon Prime Air and Cruise Self-Driving and previously worked at Lockheed Martin and NASA on Planetary Spacecraft. I studied Aerospace Engineering at MIT and did a dual MS/MBA degree at Harvard.

I am the cofounder of Wardstone, where I lead the technical development of next-generation defense spacecraft. Previously I worked at Astranis, building, launching, and operating geostationary communication satellites. I hold a bachelor's in mechanical engineering from Cornell University. At Cornell, I was the Chief Spacecraft Engineer for a lunar CubeSat mission that demonstrated novel electric propulsion and navigation systems.
