It's unclear why Shellen is leaving or where he's headed. While his LinkedIn profile says $4, the company confirmed with Business Insider that Shellen has indeed left.
"We can confirm that Jason has left Slack," a Slack spokesperson said. "He wound down his time at the company in late December to pursue a path closer to his entrepreneurial roots."
As head of product, Shellen was largely in charge of Slack's platform business, the company's effort to make its messaging app a broader workplace service that takes care of things like expense reports or meeting notes. Slack recently launched an $80 million fund to support this initiative.
Shellen's departure is the second high-profile executive loss for Slack in recent months. In November, its $4, leaving a huge position empty for the fast-growing startup.
The departures come at a tough time for Slack. The company is battling two new big-name competitors, with $4 service and $4 products both aiming to scoop up the business users that have flocked to Slack's messaging platform.
For what it's worth, Shellen has a history of short stints throughout his career. In his previous position at Pinterest, he only lasted 10 months, while he only worked 10 months at his job before that, $4.
Despite these changes, Slack has been adding firepower to its sales side. After hiring its first sales chief Robert Frati earlier this year, Slack also $4.
