Ground Truth has raised $7 million in a second round of financing after coming out of stealth mode in January.
The Seattle-based company collects data from carriers and other infrastructure companies to see the real traffic logs of the mobile internet, and then sells that data to operators, advertisers, publishers and others. By using a large sample size, the company hopes to have more accurate figures than previously available through other sources, such as surveys and monitoring services.
New investors in the round include Emergence Capital Partners and OPENAIR Ventures. Other participants include Steamboat Ventures and Voyager Capital. The company has now raised a total of $9.6 million.
