Pinterest Acquires Jelly, the Search Startup Created by Twitter Co-Founder Biz Stone

San Francisco-based Pinterest has acquired Twitter co-founder Biz Stone's "human powered" search engine startup Jelly.

"This is the best decision for the future of human powered search and discovery. Jelly plus Pinterest is an exceedingly powerful match. A new adventure begins!" Stone, Co-Founder and CEO, Jelly Industries Inc, said in a statement on Wednesday.

Financial terms of the deal have yet to be disclosed, nor whether Jelly would remain separate or be integrated with Pinterest.

"We're still working out details, so there are unknowns," Stone said.

Jelly offers a search engine service that answers user's questions in detail. To answer the user's questions Jelly routes them to people who might know.

"Human powered search, a subjective search engine, and discovering things you didn't know you need to know. These are all key to Jelly!" Stone said.

But for all the fame of the co-founders and hype when it first launched, Jelly's business never really took off, TechCrunch reported.

The app has only ranked in the top 1,500 for iOS sporadically since launching in 2014, so it is hard to get reliable download estimates, according to Sergey Bystritskiy, Director of Data Science, SensorTower.

It is currently ranked at No 1,293 for the Social Networking category on iPhone in the US. It is not currently ranking on Google Play in the US, the report said.
