Which Biz Stone-founded search company did Pinterest acquire in 2017?

Pinterest acquired Jelly Industries, the Biz Stone-founded search company, in 2017.

Jelly was founded by Biz Stone, a Twitter co-founder, and Ben Finkel. Its best-known product was Jelly, a question-and-answer service that let people ask questions and receive responses from friends, friends of friends, and the broader community. The concept combined social networking with human-powered search rather than relying only on a conventional search index.

Pinterest announced the acquisition in March 2017. The deal was intended to bring Jelly’s team and search-related expertise into Pinterest as the visual platform continued moving toward discovery, recommendations, and visual search. Financial terms were not publicly disclosed. Stone joined Pinterest as a special adviser, while Finkel joined the company full time.

A likely source of confusion is that Jelly was often described as a Q&A app, not simply a traditional search engine. It was also distinct from Aardvark, another social question-answering service, and from Quora, the larger knowledge-sharing platform. The company name Pinterest acquired was Jelly Industries.
