Instacart President Carolyn Everson is leaving in about four months at the food delivery company

Instacart’s Ms. Simo said in a statement that the company is grateful to Ms. Everson for her contributions and her departure was a joint decision. Ms. Everson started working at Instacart in early September.

Ms Everson’s plans to leave have been previously reported by CNBC, and come after chief revenue officer Seth Dallaire left in October.

Ms Everson wrote in a Facebook post on Friday that she will be taking some time off while thinking about her next steps, when she turns 50 next Friday. Ms Everson said that she and Ms. Simo agreed that her departure was the best decision for Instacart and for her personally.

“I can’t wait to watch and cheer for the team’s journey and success,” Everson wrote.

Ms. Everson spent more than 10 years at Facebook, overseeing relationships with advertisers. She began as president at Instacart, leading the company’s business development, advertising and retail teams, among others. She is one of the famous employees recruited by Facebook along with Ms. Simo and Asha Sharma, the chief executive officer of Instacart.

Ms. Simo previously led the social media giant’s mobile and product teams, and served on Instacart’s board before taking over as CEO.

San Francisco-based Instacart’s business boomed last year as people order more groceries online and avoid going shopping in person, because of the pandemic. However, grocery delivery is still expensive, and the company is looking for ways to offset the cost by expanding its advertising business.

The company, which said it plans to go public, and now has a valuation of $39 billion, is also expanding its grocery business. Instagram has been extended to 30-minute delivery with retailers like

Kroger Have.

and Publix Super Markets Inc. The company recently acquired a cart maker and a catering software company.

Amazon.com Inc.

Instacart in July said it will start building fulfillment centers for supermarkets over the next 12 months, in partnership with technology company Get Fabric Inc. The warehouses will be located in or near grocery stores, with a capacity of 10,000 to 50,000 items, according to Instacart.

At such fulfillment centers, the company will use robots to pull items from warehouses and have Instacart workers pack and deliver orders. Instacart is now rolling out shoppers to pick up products from grocery stores and deliver them to people’s homes.
