Billionaire Adam Neumann is trying to buy back bankrupt real-estate company WeWork, which he founded in 2010 and was ousted from in 2019, DealBook reported Tuesday.

Neumann, his startup Flow and Dan Loeb’s Third Point fund have “consistently expressed” a “sincere interest” since December 2023 to buy WeWork and its leases out of bankruptcy or provide debtor-in-possession, or DIP, financing, according to a letter obtained by Dealbook from Neumann’s counsel, Alex Spiro.

Those efforts have stretched even further back than December, according to the letter. Neumann had tried to arrange financing of up to $1 billion in October 2022 but was rebuffed by former CEO Sandeep Mathrani.
