Stratolaunch Team
Executive Team
PAUL G. ALLEN
Founder and Chairman, Vulcan Inc.

Allen funded SpaceShipOne, the first private spacecraft to carry a civilian into suborbital space and safely home again—a historic triumph that in 2004 earned the Ansari X-Prize. Allen’s founding of Stratolaunch seeks to build upon this success in space flight by achieving yet another breakthrough—the advancement of airport-style access to low Earth orbit, which Allen believes will open scientific and technological possibilities for humanity and our planet’s future.
