Kleiner Perkins Caufield & Byers at an event Thursday provided a look back at the performance of the iFund slightly more than three years since it was first started. The group considered it a success as it had decided to fund 25 companies that, combined should have 300 million downloads by the end of 2011. Two of the companies, ngmoco and Pelago, had found buyouts, while exercise-oriented Worksmart Labs was getting funding to expand beyond Android and develop iOS apps.
