Meghan Markle appoints former Bill Gates staffer to key role in growing business empire

Meghan Markle means business.

The Duchess of Sussex has appointed former Bill Gates employee Sarah Fosmo to be her first chief of staff as she expands her professional empire, Page Six can confirm.

Fosmo previously worked in the Microsoft co-founder’s office as deputy director of executive administration until December 2024.

Markle’s new senior advisor has experience “managing complex, high-stakes operations for ultra-high net worth individuals” and “being trusted with confidential matters,” per Fosmo’s LinkedIn page.

The move comes as the “Suits” alum, 43, now has a full plate with her As Ever lifestyle brand, Netflix series “With Love, Meghan” and “Confessions of a Female Founder” podcast, which all launched in the past several months.

Fosmo will oversee this “dynamic period of growth,” according to the Telegraph, which was first to report the news.

Meanwhile, a source tells Page Six that Lianne Cashin will continue her role as head of operations for Markle and Prince Harry’s Archewell organization after nearly four years.

The Duke of Sussex, 40, currently does not have his own chief of staff.

A rep for the couple did not immediately respond to Page Six’s request for comment.

The pair’s former chief of staff Josh Kettler abruptly left in August 2024 after only three months in the position.

“There were aspects of it that he wasn’t comfortable with,” an insider claimed to the Daily Mail at the time. “He thought it was better to leave now than to continue in a job that he did not enjoy.”

Meanwhile, a separate source told People that Kettler’s exit was a “mutual” decision with Markle and Harry since he had been hired on a trial basis.

They all allegedly agreed that he wasn’t the “right fit” for the role.
