BOULDER - Gnip Inc., an aggregator of social-media data, has been approved to receive up to $45,000 in tax and fee rebates from the city of Boulder.

The rebates were authorized for sales and use taxes, and permit-related fees.

"Gnip is a fast-growing company in Boulder's thriving downtown and high-tech communities," said Jane Brautigam, Boulder's city manager. "The city is very pleased that it can support Gnip's expansion so it can grow as an industry leader, delivering 3 billion social media activities per day."

The flexible rebate program is one of the city's business incentives, covering a wide range of fees, equipment and construction use taxes.

Gnip partners with Twitter, Facebook, Tumblr and WordPress, among others, to aggregate social-media data and information for its clients.

Gnip's 50 employees recently expanded into a new space at 1050 Walnut St., Suite 115, to maintain its presence in downtown Boulder. In addition, Gnip was named "best place to work" by the Boulder Chamber and the Denver Business Journal.

"We're excited to be based in Boulder, and we think our growth is facilitated by the many advantages offered by the city of Boulder," said Gnip's chief executive Jud Valeski. "We think Boulder offers the world's best place to work and live."

The flexible rebate program uses social, community and environmental sustainability guidelines. Companies choose the guidelines that best fit their circumstances, but must meet minimum requirements in order to receive the rebate.

The company initiated the Gnip Gives Back program, which coordinates charitable giving and organizes group service opportunities for the company to participate in.

Gnip also offers Eco Passes, Boulder B-Cycle memberships and annual Boulder city recreation passes to its employees. It is located in a LEED Gold certified building.
