Mobile payments provider Boku has raised USD 25 million in series C capital led by DAG Ventures with continued participation from Benchmark Capital, Index Ventures and Khosla Ventures.

The Boku payment technology allows users to click on the "Pay by Mobile" button on the merchant’s checkout page and instead of entering their credit card number or turning to an online payment service, they have to input their phone number as well as their mobile provider.

Boku introduced its service in June 2009 and it currently has over 1,000 direct mobile payments partners, with a global coverage in 56 countries across 190 carriers. The company now reaches over 1.8 billion consumers worldwide, and is funded by leading entrepreneurs and venture capitalists Benchmark Capital, DAG Ventures, Index Ventures and Khosla Ventures.
