Neumann's party-boy past is well-documented. Neumann told Baruch College's graduating class in 2017 that when he first arrived in New York, he spent much of his time clubbing, "hitting on every girl in the city," and trying to get rich, New York Magazine reported.

Now, Neumann is struggling to take WeWork parent The We Company public; its IPO has already been delayed after facing weak investor interest. The We Company is now considering a valuation in the range of $10 to $12 billion for its IPO - down from its $47 billion private valuation in January - according a report from Reuters.
