Slack co-founder and CEO Stewart Butterfield will leave the organization next month. 

Business Insider broke the story on Monday. Salesforce, the parent company of Slack, confirmed the development in a statement to TechCrunch. CEO Stewart Butterfield will be replaced by Lidiane Jones, executive vice president and general manager of Salesforce’s digital experience clouds.

Butterfield joined Salesforce last year following the software giant’s $28 billion acquisition of Slack. The firm was previously traded on the New York Stock Exchange (NYSE). Slack secured more than $1.2 billion from investors before going public in 2019 at a value of $21 billion.

Butterfield’s work

Butterfield co-founded Slack in 2013. He previously founded photosharing website Flickr. In addition, Butterfield was a founding partner of videogame development company Tiny Speck. Slack was initially developed as an internal collaboration tool for Tiny Speck.

“Stewart is an incredible leader who created an amazing, beloved company in Slack”, Salesforce stated today. “He has helped lead the successful integration of Slack into Salesforce.”

In an internal message to Slack staff, Butterfield reportedly indicated that his intended resignation is unrelated to the news of Salesforce co-CEO Bret Taylor stepping down next month. Butterfield stated that he has been planning his departure for a while. According to the CEO, the timing coincidentally aligns with Taylor’s leave.

Leadership changes

Butterfield added that two other Slack leaders will resign shortly. CPO Tamar Yehoshua and VP Jonathan Price are preparing to leave Salesforce.

Moreover, Salesforce subsidiary Tableau recently announced that CEO Mark Nelson will step down from his position. Nelson rose to the role after joining Tableau as an executive vice president of product development in 2018.

Salesforce acquired Tableau through a $15.7 billion deal in 2019. The company develops a popular data visualization platform with the same name. Businesses use the software to transform data into understandable graphs and dashboards.
