Salesforce's chief marketing officer Stephanie Buscemi has left the company after six years, she announced on Twitter on Tuesday afternoon.

"Change is constant, and our biggest leaps of growth are with change," she said in a post announcing the departure.

She'll be replaced by Sarah Franklin, a 13-year company veteran perhaps best known as the founder of Trailhead, its online training tool. As executive VP & general manager of Platform, Trailhead & Developers at Salesforce, Franklin oversaw the company's relationship with external software developers building on its platform.

Buscemi's departure comes about a month after outgoing CFO Mark Hawkins announced his plans to retire at the end of January. It also comes soon after Salesforce announced a $27.7 billion deal to buy Slack, in what's slated to be its biggest acquisition yet. It's also another sign of change within Salesforce's C-Suite, almost a year after former co-CEO Keith Block departed the company.

Buscemi led marketing at Salesforce, and had been at the company since 2014. Prior to her promotion to the C-Suite in 2018, she led the product marketing organization and oversaw go-to-market strategy across all of Salesforce's products. She was also instrumental in putting on Dreamforce, Salesforce's biggest annual conference, which attracts hundreds of thousands of attendees. 

In a 2019 interview Buscemi told Business Insider that companies can't just be about capitalism today: They have to be "values-driven" in their approach to everything from marketing to billing to customer support, including by making sure those values remain apparent in the "good times and the bad times."

Franklin, meanwhile, has been instrumental in Salesforce's growth, helping expand its ecosystem of developers and administrators. 

She founded Trailhead in 2014 as a a free online learning tool to help people hone the skills needed to get a job using Salesforce software. Franklin credits a conversation with Salesforce CEO Marc Benioff for giving her the idea, which has since grown into a platform with over 2 million users that now teaches technology skills from the likes of Amazon and Google as well. 

"Companies are looking to go digital faster than ever right now and they need people with those skills," Franklin told Business Insider earlier this year.
