—New money: Fisher declines to say how much the KPCB round is—it’s “significant”—but says: “The application of the funding is to help Shazam accelerate, continue to build its userbase and expand geographically as well as develop the product.” Its initial investment was £11.5 million (now $18.3 million) from Acacia Capital and DN Capital. Times Online: “Of KPCB’s 520 investments, only three have been in Europe.”

—Public offering plans: The obvious question for a growing, profitable business is, would you consider an IPO? “We would,” says Fisher. “We’re venture backed and ultimately we want to deliver a return to our shareholders. As we look to the future we absolutely think we have the size and the scale to launch a public offering.” Fisher says it’s “not on our minds right now” and is a more long-term goal.

—Freemium model: Shazam currently has a confusion of different pricing models: the iPhone app is free but Nokia (NYSE: NOK) users pay $4.99 on the Ovi store. But by the end of the year, across all platforms, Shazam will be available either as a free version with a maximum of five monthly song recognitions or as a $5 (£3.14) app with unlimited tagging and additional features—the same model introduced last week for Windows Mobile handsets.

—Ads important, but not enough: Fisher says ad rates for Shazam have been “improving” in the last three months but it’s still not enough: “We’re a profitable company and we want to stay profitable…we don’t think today mobile advertising is of the level that could sustain a business of the size we’re operating.” Shazam ad aren’t going anywhere—this week the company signed a targeted ad deal with 4th Screen. The company also earns commission on songs users buy through links sent to retailers.
