WeWork's top communications executives are jumping ship as the company struggles to go public

Overseeing public relations for WeWork is no easy task right now, with its S-1 filing panned as cultish and valuations that change week by week. 

The office responsible for telling that story has also seen its share of tumult, with two senior executives leaving recently. A company spokesman declined to comment, citing the firm's quiet period ahead of the initial public offering.

Last week, the firm's first communications hire, Jennifer Skyler, announced her departure. She'll join American Express next month as chief corporate affairs officer. 

Skyler ran WeWork's communications until April, when Jimmy Asci took over. Asci came from the advisory firm Teneo, where he was part of a team that worked with Uber's former chief executive Travis Kalanick. After Asci joined WeWork, Skyler transitioned to running CEO Adam Neumann's office, including his public-relations efforts. Skyler declined to comment on her departure from WeWork. 

In July, Dom McMullan, the firm's head of corporate communications, who reported to Asci, said he was leaving after three and a half years with the company. McMullan declined to comment and has not announced his next move. 

"He decided that it was time to go. He had been there for a long time," a source with knowledge of McMullan's departure said.  

Skyler and McMullan both left as WeWork was gearing up for an IPO that's seen a number of public missteps, including governance issues that the company worked to correct through a new filing last week and revised valuations. WeWork is now considering going public at a $10 billion to $12 billion valuation, well under the $47 billion valuation in its last round of fundraising.
