Social data platform DataSift on Tuesday announced raising $15 million in a Series B funding led by Scale Venture Partners and including Northgate Capital and Daher Capital.

Launched last year, the startup allows companies to aggregate and analyze historical social data from Twitter, Facebook and other social properties to gain insights on brands, businesses, financial markets and public opinion.

"We have the world's best infrastructure in real-time, as well as historical processing of social data, and through our Series B funding, we now have the ability to take that infrastructure to the next level," said Nick Halstead, DataSift founder and CTO, in a statement.

DataSift says it has almost 300 corporate customers, up from 200 a quarter ago, including Fortune 500 companies. It operates offices in New York, San Francisco, Chicago, and Reading, U.K. In connection with the investment, Rory O’Driscoll, a managing partner with Scale Venture Partners, will join the DataSift board.
