Slack’s chief product officer Noah Desai Weiss is stepping down, two sources with knowledge of the matter tell Fortune, leaving no remaining members of the service’s early executive team.
In a message he posted to the workplace messaging service, acquired by Salesforce in 2021, he referenced personal matters as behind his departure.
“I will always cherish the many years I’ve had working with and learning from this incredible group of people who have truly changed how the world works,” wrote Weiss in a sign-off message on the company Slack.
Desai Weiss joined Slack in January 2016 and went on, during his first two years at the company, to start its search, learning, and intelligence division, which included delivering AI-enabled capabilities, according to his LinkedIn.
A spokesperson for Slack told Fortune: “We are grateful for Noah’s contributions over the years, and wish him the best in his next chapter.” This person noted that in the interim, Slack’s product strategy will be jointly led by Slack CEO Denise Dresser and CTO Parker Harris, who is also a Salesforce cofounder.
His exit follows Fortune’s reporting on Slack’s original chief technology officer, Cal Henderson, departing the company in January. A Slack cofounder, Henderson started in 2009 and left in March 2024. Henderson was replaced by Salesforce cofounder Parker Harris. Slack founder Stewart Butterfield stepped down last year as CEO. He was replaced by Lidiane Jones, who herself left before the year was over.
“It’s changing as a lot of the more tenured folks leave, but there’s still a lot of long-term people that are rolling their eyes,” a Slack employee who requested anonymity because they weren’t authorized to speak publicly, told Fortune in January. “Especially considering execs have like a year shelf life here. A lot of jokes about what they’re actually going to accomplish here. Lots of concerns around the pivot from product culture to sales culture, too.”
