The cash infusion is led by Index Ventures and rounded out by the likes of Ron Conway, Jeff Clavier, Jason Calacanis, Chris Sacca's Lowercase Capital and Betaworks.
Betaworks is the NYC-based startup incubator and investment firm where Chartbeat, Bit.ly and a few others got their start; the firm currently holds shares in Twitter, Groupon, Tumblr and a slew of other startups in the social, real-time and structured data spaces.
Chartbeat's team said in a statement that they chose to accept funding from Index because they believe that firm is uniquely positioned to help the company with international expansion. "Chartbeat is already kicking ass on major sites from Denmark (Ekstrabladet) to India (Times of India) to South Africa (News24)... and we want to expand on that," it said.
The startup, which currently counts around 2,500 paying customers (a nice workload for the company's five employees, we're sure), focuses on delivering real-time analytics and traffic data for websites. Its customers include such vast web presences as Threadless, The Onion, The New York Times, Forbes.com and Gawker Media. Each customer pays between $10 and $150 per month for access to the Chartbeat dashboard. If you do the math, that puts Chartbeat somewhere in the $25,000 to $375,000 range for monthly revenue so far -- not bad for a service launched just more than a year ago.
