Pinterest may have beat on revenue and earnings in the first quarter, but the company is not out of the woods yet when it comes to carving out a place for its service in today’s competitive landscape. In particular, Pinterest is up against a credible threat with the rise of TikTok when it comes to social commerce. The idea that you could be inspired to shop by browsing media shared by others is an experience that Pinterest, in a way, helped pioneer, with its pinboard-style website where users often saved ideas of things they were considering buying or trying.

But these days, the more common refrain among influenced and inspired shoppers is “TikTok made me buy it,” not “I found it on Pinterest.”
