SOFTBANK Corp has invested $200 million in InMobi. The funding will take place in two tranches- $100 million in September 2011, followed by an equivalent tranche in April 2012.

InMobi?s investors include Kleiner Perkins Caufield & Byers and Sherpalo Ventures. The $200 million investment will help the company create value across the mobile ecosystem globally through advertising, mobile payments using SmartPay, and HTML5 rich media production and distribution using the recently acquired Sprout platform.

This partnership will provide Softbank and InMobi with opportunities to further explore global scale collaboration in the fast growing mobile ad market. It is also expected to generate further synergies between InMobi and Softbank, given the significant number of prominent Asian Internet companies in Softbank?s investment portfolio.
