I've been listening to:
"Hatching Twitter: A True Story of Money, Power, Friendship, and Betrayal"
https://www.amazon.com/dp/B00CDUVSQ0/
As you can tell, it's the kind of thing meant for the best seller list and isn't a scholarly work or anything, but the preface stresses it's based on lots of interviews.
If nothing else, it's a fun read and the background of the founders is pretty interesting.
