The company has been running for just over a year and in that time has amassed 2,500 paying customers, including Time.com, the Chicago Tribune, the New York Times and Gawker Media.

Gawker’s new beta site is held up by Chartbeat as a model of what its analytics service can do. Gawker’s editors, it says, use the data to make decisions about what stories to show where. Data is fed back via a dashboard, an example of which can be found here.

Led by general manager Tony Haile, Chartbeat has a staff of five. Announcing the investment on its blog, the company wrote: “We’re going to take this team of hardcore C coders, genius data scientists and all-round Python hackers and build Chartbeat into the ‘Intel Inside’ of websites everywhere.”
