Mobile music specialist Shazam has secured investment from Google and Amazon backer Kleiner Perkins Caufield and Byers (KPCB).

The US-based venture capital firm, which is investing from its $100 million (£63 million) iFund, joins Shazam’s existing investors DN Capital and Acacia Capital.

Matt Murphy, a partner at KPCB and manager of the iFund, says, ‘We’ve met hundreds of companies and received thousands of mobile app business plans, but none have distinguished themselves on par with Shazam.’

The London-based company, whose application enables listeners to ‘discover’ music through their mobile phones, will use the money raised in this latest round to expand its service worldwide by covering additional mobile platforms and languages.

More than 50 million people have used Shazam’s service worldwide, an increase of 15 million since February this year, according to the company.

Founded in 1972, KPCB has offices in the US and China and has backed companies including Google, Amazon, AOL, Lotus, Symantec and Sun Microsystems.
