Ubers lie was it would be profitable at scale. They were never profitable at all while growing, but always claimed that if they just had a few more markets they'd finally be profitable.

Super Pumped: The Battle for Uber is the most well-known tell-all book. I think they also made a TV miniseries based on the book but I haven't watched it yet.

Wild Ride: Inside Uber's Quest for World Domination is mostly a summary of the headlines involving the company rather than a tell-all but it's accurate enough if you want to familiarize yourself with the subject.

I don't believe anyone has written a book about the technology team specifically which is sad because they actually made some really great technology, especially in the monitoring space, and I would love to hear the story of how that came to be.
