Doug Sinclair is the owner of Sinclair Interplanetary, a manufacturer of spacecraft components. There are more than 75 satellites on-orbit today using Sinclair hardware to help point their payloads (telescopes, antennas, etc) at their targets.
Sinclair is notable in that it has never had any investment, debt, or government grants. Starting with retained earnings from 3 years of employment as a junior engineer, Doug has organically grown this organization to a $10M / yr profitable venture.
When not building satellites, Doug enjoys aviation as a private, instrument-rated, multi-engine pilot.
