Cue (formerly Greplin) is a website and app that pulls information from online accounts to present an overview of a user's day. The company was founded by Daniel Gross and Robby Walker. Cue operates by linking various user accounts belonging to a registered individual and running a query search for keywords within those applications or accounts. For example, someone may want to use a single search feature to check their Facebook, LinkedIn and Twitter accounts without signing in and checking each one individually. Cue acts as a desktop search, indexing online social networking accounts, thereby creating a personal cloud. Cue offers a free version that allows users to add a certain number of accounts, while a paid version allows users the option to 'unlock' other sources and get more index space. In 2011, Cue raised $4 million in funding from venture capital firm Sequoia.
