Which startup was founded by Adam Neumann?

Adam Neumann founded WeWork.

Neumann co-founded WeWork in 2010 with Miguel McKelvey after the pair had worked together on GreenDesk, an environmentally focused coworking business in Brooklyn. They sold their interest in GreenDesk and used the proceeds, along with early investment, to launch WeWork. The company’s first WeWork location opened in Manhattan’s SoHo neighborhood in April 2011.

WeWork became known for leasing office buildings, redesigning them, and renting workspaces to freelancers, small businesses, and larger companies. Neumann served as chief executive until 2019, when he stepped down amid scrutiny of the company’s governance, finances, and proposed initial public offering. The company later went public through a merger in 2021 and filed for bankruptcy protection in 2023.

A common mix-up is crediting Neumann as WeWork’s sole founder. Miguel McKelvey was also a co-founder, but the question asks which startup Neumann founded, making WeWork the single canonical answer. Breather, Spaces, and Regus are separate workspace businesses, not the company he founded.
