About Us

On October 5, 2011, history quietly was made near the small town of Warkworth, Ontario, Canada. That day saw the first manned flight of a fixed wing all-electric VTOL aircraft. This event prompted the formation of a stealth company with the sole purpose of pursuing the development of this new unique technology. In September of 2014, the Company reorganized as Opener and relocated the majority of its operations to Silicon Valley in California to pursue an unencumbered and accelerated development timeline.
