The cofounder and CTO of Slack is leaving the company, Fortune has learned, the latest in a string of leadership changes that puts executives from parent company Salesforce in near total control of the top ranks of its workplace chat subsidiary.
Cal Henderson, Slack’s chief technology officer and sole remaining cofounder, is stepping down from the role effective immediately, but will remain at the company until March 1, according to a memo viewed by Fortune. He will be replaced by Salesforce cofounder and CTO Parker Harris, who will shift his focus to the Slack business. It was not immediately clear who will replace Harris as the Salesforce CTO.
