San Francisco -- Flurry, the San Francisco-based developer of a smartphone app analytics, promotion and monetization platform, said on Tuesday it has raised $15 million in its third round of funding. Menlo Ventures led the round, which also included participation from previous backers Draper Fisher Jurvetson, InterWest, First Round Capital and Union Square Ventures. The company, which also raised $7 million in a round that closed in January, plans to use the proceeds to expand the reach of its Flurry Analytics and AppCircle services across mobile application platforms such as iOS and Android. It also plans to expand sales and marketing, as well as accelerate the development of new services. Flurry's platform is used by more than 35,000 companies. In November, the company measured 5 billion end-user sessions from more than 100 million unique devices.
