Stewart Butterfield speaks on November 08, 2019 in San Francisco, California.
- Salesforce said Monday that Stewart Butterfield, who joined the company through the Slack acquisition, is leaving the company.
- Salesforce bought Slack for about $27 billion in a deal that closed in mid-2021.
- Butterfield's departure comes just after Salesforce co-CEO Bret Taylor stepped down last week.
Salesforce said Monday that Slack founder and CEO Stewart Butterfield is leaving the company. He'll be succeeded by Lidiane Jones, an executive vice president at Salesforce who joined in 2019.
Butterfield's announced departure comes days after Salesforce said co-CEO Bret Taylor was stepping down just a year after being promoted to share the top job with Marc Benioff, Salesforce's co-founder.
Benioff informed employees on a call on Monday that Butterfield was leaving, according to people familiar with the matter who asked not to be named because they weren't authorized to speak on the record. Salesforce acquired Slack for about $27 billion last year, its largest purchase ever. The deal was announced in late 2020.
"Stewart is an incredible leader who created an amazing, beloved company in Slack," a company spokesperson told CNBC in a statement. "He has helped lead the successful integration of Slack into Salesforce and today Slack is woven into the Salesforce Customer 360 platform. Stewart also was instrumental in choosing Lidiane Jones as the next Slack CEO to lead it into its next chapter. Lidiane has a strong background in customer and enterprise tech and has been among Salesforce's leadership for over three years. We're grateful for Stewart and excited for Lidiane as she takes over the reins of Slack."
Tamar Yehoshua, Slack's product chief, will also depart, along with Jonathan Prince, senior vice president in charge of marketing, brand and communications, the people familiar said. Noah Weiss, senior vice president of product at Slack, will succeed Yehoshua, Butterfield said in a Slack message to all Salesforce employees that CNBC viewed.
Jones spent more than 12 years at Microsoft, before leaving to join Sonos in 2015. She's been at Salesforce since 2019 and is currently executive vice president and general manager of digital experience clouds.
Money Report
Butterfield originally worked with the other co-founder of Slack, Cal Henderson, at photo-sharing website Flickr, which Yahoo acquired in 2005. In 2009 the two men founded Tiny Speck as they sought to build an online video game named Glitch. The game failed to become a world-beating hit and Tiny Speck shut it down. Tiny Speck had developed software employees had used to build Glitch, and the startup made the software available to the public as Slack in 2014.
It grew quickly, mobilizing Microsoft. When Microsoft launched Teams in 2016, Slack took out an ad in The New York Times to welcome Microsoft to the market.
"I'm not going to do anything entrepreneurial," Butterfield wrote in the Slack message. "As I said in my announcement to Slack team, these days my fantasies are about gardening. As hackneyed as it might sound, I really am going to spend more time with my family (as well as work on some personal projects, focus on health and generally put time into those things which [are] harder to do when one is leading a large organization)."
In March 2020 Butterfield met with Taylor and told him Slack wanted to acquire Quip, the productivity app Taylor sold to Salesforce in 2016, from Salesforce. Months later, Taylor told Butterfield that while Salesforce wasn't interested in selling Quip to Slack, Salesforce was interested in buying Slack.
Butterfield said that the leadership changes at Slack were not related to the announcement of Taylor's resignation from last week. "We've been planning this for a while," Butterfield wrote.
