I believe Google Ventures did, but that's not exactly the same entity.
Yes, they invested $250m at a $3.5bn valuation, estimated to be 2-7% ownership currently[1]. Makes me wonder: if Uber is found liable for a huge amount that would bankrupt them, could there be a situation where Waymo absorbs Uber as a post-trial settlement rather than Uber being liquidated?
With Levandowski remaining an agent of Google/Waymo all along?
I don't think so, Levandowski would be up on criminal charges or pleaded guilty to get a lesser sentence. Either way if if there is any truth in it, no one is going to hire the guy ever again.
