Meet the Development Team

Assen Andonov
Founder & CEO
Assen Andonov Founder & CEO
At thirteen Assen built his first airplane, started gliding at 15, parachute jumping at 17 and flying powered aircraft at 18. At 23 he co-founded a company that designed and manufactured numerous types of airplanes. At 25 he started a company for B2B imaging solutions that grew to become the market leader in the field. For the last two and a half years he’s been developing the Wasp T1 VTOL personal aircraft. This aircraft is significantly more energy efficient and safe than all known competition. Assen is also a commercial pilot and a former management consultant, well versed in growing businesses and actualizing dreams.

Dr. Jan Kratochvil, Flight Test Engineer, Test Pilot
Jan has an M.S. in theoretical physics from the Swiss Federal Institute of Technology Zurich (ETHZ) and a Ph.D. from Stanford University. He turned to aerospace after over a decade of research studying the origin and evolution history of the universe. His primary focus is currently on flight testing from both the engineering and pilot perspectives. Possessing flight experience in airplanes, gliders, and helicopters, he founded Academic Flight LLC, where he uses flight test methods as cockpit teaching tools combined with the test pilot’s knowledge of flight dynamics, for advanced airmanship development of pilots.
Jan’s teaching interests transcend human flight instruction. Applying his background in high performance computing and machine learning, he aims towards a future of pilotless air and ground transportation, when vehicles will learn to fly and drive autonomously.
