Board of Directors

Jeff Greason

Jeff Greason

Board Chairman

Jeff Greason has over 25 years’ experience managing innovative technical project teams at XCOR Aerospace, Rotary Rocket and Intel Corporation, and now as CEO of Agile Aero. As president and co-founder of XCOR, he led the engineering team that developed over 14 different long-life, highly-reusable liquid-fueled rocket engines. He has also worked on a low-cost liquid propellant piston pump, and two manned reusable rocket aircraft – the EZ-Rocket and the X-Racer, which broke all previous barriers for low cost and rapid reflight of rocket vehicles with 66 successful flights between them.

Jeff is a recognized expert in reusable launch vehicle (RLV) regulations.  He has been a member of the COMSTAC RLV working group since 2000 and presently serves on the full COMSTAC, and he was integral in the first spaceport license at an airport, in Mojave, California, and the first spaceport license at a scheduled air service airport, in Midland, Texas.  He was one of the architects of the regulatory policy embodied in the 2004 Commercial Space Launch Amendments Act; following which he co-founded the trade association for the commercial space industry, now the Commercial Spaceflight Federation.  He also recently took over as Chairman of the Board at the Tau Zero foundation, a non-profit group working towards practical interstellar transportation technologies.

In 2009 he was named by the White House to a panel of independent experts that examined alternatives for advancing the United States’ human space exploration agenda. Chaired by Normal Augustine, the Review of U.S. Human Space Flight Plans Committee examined ongoing and planned NASA activities and present options for a safe, innovative, affordable, and sustainable human space flight program after the retirement of the space shuttle.  He has remained active in national space transportation policy and has given several widely circulated speeches on the subject.

Greason was cited by Time magazine in 2001 as one of the “Inventors of the Year” for his team’s work on the EZ-Rocket. In 2016 the National Space Society awarded him the Space Pioneer Award for Entrepreneurial Business.  Mr. Greason holds 25 U.S. patents. He graduated with honors from the California Institute of Technology in Pasadena and currently lives in Midland, Texas.

Daniel José Marie from an early age had a fascination with dinosaurs, the deep sea, and deep space. In his teens he built rockets, power amps, model T-Rex’s, boats, space stations, airplanes, and go-karts.  He started and sold his first company while he was at university studying mathematics and has been a serial entrepreneur. Daniel believes there is already a child born today that will never die. He is interested in the challenges facing humanity, especially the future of work, and what it will mean to be conscious when the first human is ‘printed’ in a spaceship orbiting the nearest Exoplanet. Under the guise of the “Deep Space Cowboy”, Daniel evangelizes on opportunities presented by the New Space industry, the democratization of space, and that everyone equally owns and shares in the future.


Back on earth, Daniel is an executive producer and corporate advisor who has taken many concepts and ideas from origination thru to active projects, in Australia, Asia Pacific, and China. He has advised on high-speed rail projects in the region, the establishment of the Asian Le Mans motorsport series in 5 countries in Asia, modern agricultural carnivals, building the first monster truck in China, and numerous collaboration, joint venture, M&A, and funding transactions in tech, banking, and financial risk management, and cybersecurity.
