Gnip, Inc. was a social media API aggregation company. Headquartered in Boulder, Colorado, it provided data from dozens of social media websites via a single API. Calling itself the "Grand Central Station for the social web", Gnip was among the first social media API aggregation services. Gnip is known as an early influencer in building the real-time web. The company has also been instrumental in defining relevant web standards: Gnips co-founder Eric Marcoullier actively advocated for adoption of open web standards, and helped define the new Activity Streams format for web data. Subsequent to a 2010 data licensing agreement with Twitter Inc, Twitter purchased Gnip in April 2014.
