Snap is instituting another round of layoffs, this time focusing on the advertising side of the company’s business, Bloomberg reports.

About 100 people will lose their jobs, the third wave of layoffs since the beginning of the year. The company trimmed its engineering staff earlier this month, and reported smaller job losses in a restructuring.

“Over the past two years our company has grown a tremendous amount. Late last year we asked senior leaders across Snap to look closely at their teams to ensure they had the right resources and organizations to support their missions. As a result, new structures have been put in place for Content, Engineering, Sales and many other parts of Snap,” Chief Strategy Officer Imran Kahn said in a statement to Recode. “These changes reflect our view that tighter integration and closer collaboration between our teams is a critical component of sustainably growing our business. While this process has required us to make some really tough decisions, we believe that rigorously ensuring our team structure always aligns with our goals will make us stronger.”

The company did not respond to a request for comment.

Snap posted a strong December quarter, though investors have been fretful about user reaction to a redesign of the app — which is supposed to make it easier to use, but has drawn criticism from users like Kylie Jenner and Chrissy Teigen.
