Tim Papandreou, a strategic partnerships manager at Waymo, Alphabet's self-driving car unit, has recently left the company, a spokesperson confirmed to Axios.

Why it matters: Papandreou, who joined Waymo (then still part of the Alphabet's moonshot division called X) in 2016, was a big get for the company. He spent several years working for the San Francisco Municipal Transportation Agency, and led its failed bid for a $50 million grant from the U.S. Department of Transportation in a national contest called the “Smart Cities Challenge." No word yet on where he's headed.

The story has been updated to correct Papandreou's job title at Waymo from head of strategic partnerships.
