If any adage applies to mobile-payment startup Boku, it's "big things come in small packages." The company, which brokers "micropayments" for games and other mobile applications, has channeled minor transactions into major funding, grabbing a healthy $25 million from its latest round of financing.

Though Boku is a new name in mobile payments, having entered the market just six months ago, it has shown meteoric growth, buying out two major competitors in its first month and raising some $38 million in venture funding to date. Though its offerings focus on the small, its scope is anything but -- it operates in fifty-eight countries, spanning nearly two hundred service providers. The company services over a thousand mobile developers, including MySpace market-leader Playdom and the equally-influential Playfish, which was itself recently grabbed in a $400 million acquisition by EA.

The recently-closed Series C financing saw reinvestments from venerable venture firms including Index Ventures, Benchmark Capital, and Khosla Ventures, with lead investment from DAG Ventures. With plenty of cash in the bank, new developers coming on board every week, and the South American market expected to open wide in short order, the company is poised to continue its exponential growth for the foreseeable future. Some observers have suggested that additional acquisitions may be on the way, though company execs are keeping to the tried and true "we can't rule anything out."
