Musk's white paper, everyone else's money
When Elon Musk published his 'Hyperloop Alpha' paper in August 2013 — passenger pods in near-vacuum tubes at airline speeds — he explicitly invited others to build it. Sherpa Capital's Shervin Pishevar, who had discussed the idea with Musk directly, took him up on it, co-founding Hyperloop Technologies in Los Angeles in 2014 with Brogan BamBrogan, a flamboyant ex-SpaceX engineer; propulsion engineer Josh Giegel, another SpaceX alumnus, was a founding team member who would eventually run the company. Renamed Hyperloop One, the startup positioned itself as the serious, funded contender in a field of renderings, promising Dubai to Abu Dhabi in 12 minutes and freight that moved at the speed of flight for the price of trucking.
Fastest thing in the desert
For a while, the engineering kept pace with the pitch. In May 2016, an open-air propulsion sled rocketed across the North Las Vegas desert in the industry's first public test, timed to an $80 million Series B. The company then built DevLoop, a 500-meter full-scale vacuum tube — the only one of its kind in the world — where the XP-1 pod hit 192 mph in July 2017 and a record 240 mph that December. The money followed: an $85 million round in September 2017 brought cumulative funding to $245 million at a $700 million valuation, and a $50 million injection from DP World and Caspian Venture Capital arrived in December alongside the announcement that Richard Branson would chair the board. Virgin's October 2017 investment had already rebranded the company Virgin Hyperloop One — a household name attached to a technology that did not yet carry anyone.
