WeWork, the troubled operator of shared office space, has named Sandeep Mathrani, a senior executive at the commercial real estate company Brookfield Properties, as its new chief executive. Mr. Mathrani, whose appointment was announced on Saturday, replaces Artie Minson and Sebastian Gunningham, the co-chief executives. Mr. Minson and Mr. Gunningham took over in September from Adam Neumann, the WeWork co-founder whose growth-at-all-costs strategy brought the company to the brink of financial collapse last year. In a statement, Mr. Mathrani said WeWork had “redefined how people and companies approach work with an innovative platform, exceptionally talented team and significant potential if we stick to our shared values and maintain our members-first focus.” The appointment of Mr. Mathrani, who is set to start on Feb. 18, would be an important part of WeWork’s attempts to build a business that could sustain itself in the fast growing but highly competitive market for flexible office space. Mr. Mathrani has been chief executive of Brookfield’s retail division since August 2018, according to his LinkedIn page. Click to read more at www.nytimes.com.
