Former Meta operating chief Sheryl Sandberg is leaving the company’s board of directors.

“With a heart filled with gratitude and a mind filled with memories, I let the Meta board know that I will not stand for reelection this May,” Sandberg wrote in a Facebook post on Wednesday.

Sandberg, 54, joined Facebook in 2008 as Mark Zuckerberg’s top deputy after spending about seven years at Google. In 2012, she became a board member at the company. During her tenure, Facebook rose from a highflying startup to become one of the most valuable companies in the world, topping a $1 trillion market cap at its peak in 2021.

Sandberg announced her departure from Meta in mid-2022, following multiple controversies that dogged the company and sullied its reputation among users, lawmakers and investors. Most notably, Facebook was central to the spread of disinformation ahead of the 2016 election and during the early days of the Covid pandemic in 2020. The company has also been in the subject of antitrust investigations and was scrutinized in Sandberg’s waning days for its insufficient efforts to combat hate on its platform.

When Sandberg stepped down as Meta COO in June 2022, she was replaced by Javier Olivan, who had been serving as Meta’s chief growth officer.

Since leaving Meta, Sandberg has dedicated much of her time on her LeanIn.org nonprofit, which focuses on empowering women tin the workplace, and related projects.

“I wanted my new chapter to be able to really make a difference,” Sandberg told CNBC Make It in August. “We’ve been in development on this since I was at Meta, but being able to have the time to put into [this launch] and to really be … a bigger part of this has meant a lot to me.”

Shortly after Sandberg’s post, Zuckerberg responded with a short reply.

“Thank you Sheryl for the extraordinary contributions you have made to our company and community over the years,” Zuckerberg wrote. “Your dedication and guidance have been instrumental in driving our success and I am grateful for your unwavering commitment to me and Meta over the years. I look forward to this next chapter together!”

Meta technology chief Adam Bosworth wrote, “Amazing run Sheryl, thank you so much for everything you did for all of us and also for me personally.”

Meta’s board consists of Zuckerberg, who serves as chairman, as well as former PayPal Executive Vice President Peggy Alford, venture capitalist Marc Andreessen, Dropbox CEO Drew Houston, former McKinsey & Company senior partner Nancy Killefer, former U.S. deputy secretary of the treasury Robert M. Kimmitt, DoorDash CEO Tony Xu and Tracey T. Travis, a former CFO at Estée Lauder.

Here’s the full text of Sandberg’s post:

With a heart filled with gratitude and a mind filled with memories, I let the Meta board know that I will not stand for reelection this May. After I left my role as COO, I remained on the board to help ensure a successful transition. Under Mark’s leadership, Javi Olivan, Justin Osofsky, Nicola Mendelsohn, and their teams have proven beyond a doubt that the Meta business is strong and well-positioned for the future, so this feels like the right time to step away. Going forward, I will serve as an advisor to the company, and I will always be there to help the Meta teams.

Serving as Facebook’s – and then Meta’s – COO for 14 ½ years and a board member for 12 years has been the opportunity of a lifetime. I will always be grateful to Mark for believing in me and for his partnership and friendship; he is that truly once-in-a-generation visionary leader and he is equally amazing as a friend who stays by your side through the good times and the bad. I will always be grateful to my colleagues and teammates at Meta for all the years of working side by side and all they taught me. And I am particularly grateful to my fellow Meta board members for their lasting friendships, the guidance they provided me for so many years, and their stewardship of products that mean so much to people all over the world.
