App Annie, the industry leader in app store analytics and market intelligence for the global app economy, today announced the company has closed $6 million in Series B financing. The round was led by Greycroft Partners, with participation from a global network of investors, including e.ventures, Infinity Venture Partners, Kii Capital, angel investor Jarl Mohn and Series A lead investor IDG Capital Partners.

App Annie’s app store data suite is ubiquitous among app publishers, journalists, VCs, media companies and platform owners alike. Eighty percent of the Top 100 Grossing iOS publishers worldwide rely on App Annie’s products for insights into downloads, revenues, in-app purchase and ranking data across categories and geographies, as well as trend analysis across the iOS, Mac and Google Play app stores. In addition, the company’s premium market data service, App Annie Intelligence, is used by major app distributors such as Nokia, as well as more than 50 percent of the Top 20 Grossing iOS publishers, including GREE and Storm8. Today’s announcement follows on the heels of the company’s entry into the Android marketplace with the launch of App Annie for Google Play.

“App stores are driving today’s digital economy,” said Dana Settle, partner, Greycroft Partners. “App Annie is an invaluable tool for any business that needs access to the highest quality app store analytics and market data. As the marketplace for mobile apps and digital goods continues to explode, App Annie is incredibly well positioned to become the de facto analytics and intelligence standard across all platforms.”

As the distribution of digital content has shifted away from the open web to digital superstores, a new standard for app store analytics and market data is required for publishers to inform their content distribution strategies. App Annie’s success to date is a result of the depth, breadth and quality of its data for the iOS, Mac and Google Play global app stores. The company will use the new funding to accelerate its product roadmap and expansion into new app stores worldwide. Within the next year, App Annie users can expect to see new analytics and intelligence services for different platforms and content areas. In addition, funds will be used to increase the company’s presence within the U.S., China and Japan, three key markets in the global app store economy. App Annie has more than 30 employees and plans to significantly increase that number within the next year, particularly in its San Francisco and Beijing offices.

“App Annie’s investors share our vision to establish a new global standard in app store market data, and collectively bring the expertise and networks required to accelerate our plans,” said Bertrand Schmitt, CEO, App Annie. “There is a clear need in the industry for high quality market data, and many businesses depend on our data to succeed in the global app store economy. Within the next year, our customers can expect to see a whole host of new feature and platform integrations for App Annie products.”
