Pinterest has long seemed like a missed opportunity to investors. It’s a platform with hundreds of millions of users that isn’t growing that fast or making much money, even though most of those users spend their time searching for and pinning stuff they’d like to buy.

Pinterest Inc said that Chief Executive Officer Ben Silbermann would step down, handing over the reins of the social media platform to Google commerce executive Bill Ready. Ready’s appointment brings end to Silbermann’s 12-year tenure as CEO, which began when he co-founded the company in 2010.

He will now take up the newly created role of executive chairman and keep his board seat, while Ready will also join the board, the company said. The news sent the company’s shares 9 percent higher in extended trading on Tuesday and underscored a shift in focus at Pinterest to e-commerce initiatives from its advertising-based business model.

Ready, 42, the company gets an executive who for the past two years ran commerce and payment operations at the Alphabet Inc-owned search giant. Ready has also held senior leadership roles at PayPal. Pinterest has grown rapidly since then and now has more than 430 million monthly active users.

Ready will receive an annual salary of $400,000 and be eligible for a stock option award to buy about 8.6 million Class A shares.

“In our next chapter, we are focused on helping Pinners buy, try and act on all the great ideas they see,” Silbermann said. “Bill is a great leader for this transition,” he added.
