What was the name of that Search Engine Startup?

Hey guys.

A few years ago, I believe it was 2009 or 2010, there was a Search Engine startup that got pretty hyped in several tech outlets. All I remember from it was from an interview where one of the founders said something like: "There's the public data that you can find through Google, and then there's your data that google can't find".

It was basically a search engine for locating your files, (personal or work) across multiple cloud services such as facebook, gmail, hotmail or whatever.

What was the name of it?

Thanks!
