Real-Time Analytics Startup Chartbeat Raises $3 Million

Chartbeat, an analytics startup that provides subscribers with a snapshot of how people are interacting with their sites — in real time — has raised $3 million in a first round of funding. The company, which was incubated at NYC-based tech investor Betaworks and launched in April 2009, pitches its service as an alternative to Google (NSDQ: GOOG) Analytics, saying that while “Google Analytics can tell you how many people loaded a page in a given time period, ChartBeat can tell you how many people kept the page open and are on it right now, and whether they are actively interacting with it.”

Chartbeat says it has 2,500 paying customers, including Gawker Media, the Chicago Tribune and DailyKos. The new funding round was led by Index Ventures. Other investors include O’Reilly AlphaTech Ventures, Freestyle Capital, Lowercase Capital and Jason Calacanis.
