WeWork

New York-based coworking/flexible-office company founded by Adam Neumann in 2010. Reached a peak private valuation near $47 billion before its 2019 IPO attempt collapsed after the S-1 filing exposed governance problems, related-party dealings, and an unsustainable long-lease/short-sublease model; Neumann was ousted. Went public via SPAC in 2021 at roughly $9 billion, filed Chapter 11 bankruptcy in November 2023, and emerged as a private company in June 2024.
