Earlier this year, Neumann's new real estate venture, Flow Global, had submitted a bid of more than $500 million to take over WeWork and its assets, Reuters has reported. "For several months, we tried to work constructively with WeWork to create a strategy that would allow it to thrive," Neumann said in his statement to DealBook. Neumann did not immediately respond to a Reuters request for comment, while WeWork, once privately valued at $47 billion, declined to provide a statement.
