Bridj, the on-demand private bus startup, said Thursday that it has raised $4 million in funding to help it expand beyond Greater Boston.
The Cambridge company also said that it hired Gabe Klein, formerly a vice president at Zipcar, as its chief operating officer.
Klein previously served as Chicago’s transportation department commissioner and as transportation department director in Washington, D.C.
The investment comes as Bridj expands its routes in Boston. But it may face regulation in Cambridge that could “essentially ban” the service in that city, founder Matt George said recently.
The funding comes from Atlas Venture, NextView Ventures, Suffolk Equity, and Freshtracks Capital of Vermont.
Individual backers taking part in the round included three early investors in Zipcar: Jill Preotle, Andy Ross, and Peter Aldrich.
Bridj aims to use data to adjust its service to the changing needs of travelers. It has been testing routes covering neighborhoods including Boston’s Financial District, Cambridge’s Kendall Square, and Brookline’s Coolidge Corner. The company intends to serve as a sort of middle ground between MBTA service and Uber, the car service.
In its announcement, Bridj did not specify where it could expand beyond Boston.
