Boom Technology (Denver Centennial) is a US start-up planning to develop and build a 40-seat civilian supersonic jet capable of travelling at Mach 2.2. The firm plans to have a one-third-scale technology demonstrator ready by early 2017.

Thus far, UK businessman Richard Branson has said his Virgin Galactic (VGX, Las Cruces) unit has signed up for ten options while an undisclosed European operator has opted for fifteen options. Virgin Galactic has committed to provide Boom with development services.

Funded by Y Combinator, Sam Altman, Seraph Group, Eight Partners, and other venture capitalist firms, Boom Technology is led by Blake Scholl.
