Ex-Hyperloop One co-founder Brogan Bambrogan just launched a rival startup

Brogan BamBrogan, the former co-founder and CTO of Hyperloop One, has launched his own Hyperloop startup.

BamBrogan and several other employees sued Hyperloop One on claims company executives allegedly misused funds, breached their fiduciary duty, violated California labor code, and even assaulted at least one employee by placing a noose on his desk seat. The lawsuit has since been settled for an undisclosed amount.

At the time of the settlement, announced last November, BamBrogan wrote a statement saying he and the other three employees that filed the suit were still "planning to build rad s**t with rad people, starting with our take on hyperloop. More to come in the near future."

On Thursday, BamBrogan announced the launch of "Arrivo - the Arrival Company," which will commercialize technology for Hyperloop systems. Arrivo will have two test tracks, one of which will be in the US, and aims to have revenue-generation projects operational in three years.

Arrivo plans to have 30 employees by June and 80 by the end of 2017, according to the announcement. The startup has secured funding but did not disclose how much.

The three employees who filed the lawsuit with BamBrogan against Hyperloop One are all listed as co-founders. They include: David Pendergast, former assistant general counsel for Hyperloop One; William Mulholland, former vice president for finance of Hyperloop One; and Knut Sauer, former vice president for business development of Hyperloop One.
