The embattled San Francisco startup, Leap Transit, is set to auction at least three of its kitted-out buses later this month through a Bay Area auctioning service. Such a sale could indicate the company is in the process of shutting down.

The buses are being listed by First Capitol Auction, Inc., a “commercial liquidator” company based in nearby Vallejo, California. Oddly, the listings make no mention of Leap Transit. Leap has not posted to its Facebook page nor its Twitter account since going dark on May 19.

Over the weekend, neither CEO Kyle Kirchhoff nor Billy Draper, one of the company’s investors, responded to Ars’ requests for comment.

The luxury private bus company halted its service in mid-May after being hit with a cease-and-desist letter from the state regulator, the California Public Utilities Commission (CPUC) for operating without a license. That move came just a month after being slapped with a complaint filed against it at the Department of Justice for being in violation of the Americans with Disabilities Act.

Records still show Leap has a pending application to operate as a Passenger Stage Corporation (PSC). In March 2015, Kirchhoff told Ars that such a license "is really about allowing us to operate outside of San Francisco" and claimed the lack of such a license didn’t impact his startup’s immediate operations.

Terrie Prosper, a CPUC spokeswoman, told Ars three months ago that "it is not legal for the company to operate without a license.”

When Ars went on a pre-launch ride with Leap in mid-March, Kirchhoff told us that the company had four buses, with another in reserve, so it is possible that the company may come back with fewer or different buses.
