Waymo, the self-driving unit of Google’s Alphabet  said that it had raised  its first external investment round and expects to add more outside investors.

The company has also disclosed that its self-driving trucking business is to be named as Waymo Via.  Founded 11 years ago as a small project inside Google, Waymo is now widely considered the leader in developing self-driving technology. But Waymo and its principal rivals are still years away from building large-scale businesses around that technology, analysts believe.

Waymo Chief Executive Officer John Krafcik, in a media briefing declined to confirm whether Alphabet plans to sell or spin off Waymo, saying it was “certainly a possibility for the future.”

Krafcik described the outside investment as part of “an evolutionary path that we had always imagined” that could lead to “more independence” for Waymo. He said Alphabet would continue to join other investors in funding Waymo.

In addition to Alphabet, initial investors include auto parts supplier Magna International Inc, with which Waymo has an assembly deal; U.S. dealership chain AutoNation Inc which services and maintains Waymo’s vehicles; the Canada Pension Plan Investment Board, and three large investment firms: Silver Lake, Andreessen Horowitz and Mubadala Investment.

AutoNation said it invested $50 million as part of the initial funding round. Figures for other outside investors were not immediately available. Silver Lake partner Egon Durban is a nominee for Waymo’s operating board. Andreessen said its partner David George led its investment but is not taking a board seat.

Alphabet CFO Porat said a more “intense focus” on “metrics and milestones” had already played out at Alphabet’s Verily health care business, which raised $1 billion from Silver Lake and others in January 2019.

“There’s a valuable added governance discipline when you have additional voices at the table,” she said. “It’s sort of somewhere between private-independent and public.”

Krafcik said Waymo plans to offer a range of self-driving transportation services, from its Waymo One ride hailing business in Phoenix through the new Waymo Via logistics business that would bundle local and long-haul delivery.
