Following a successful Series E funding round, the company has aggressively grown to expand its tech portfolio

App Annie, the San Francisco-based app data and insights platform, has acquired app marketing company AppScotch at an undisclosed amount to boost its analytical capabilities.

This is the third buyout for App Annie in two years, having acquired the Dutch firm Distimo in 2014, and Canadian group Mobidia in 2015. This acquisition follows App Annie’s own Series E funding round in January, which secured $63 million for the company’s expansion plans, bringing total investment up to roughly $157 million.

App Annie has more than 500,000 registered members— including 94 of the top 100 publishers — who use the platform to track performance and inform business decisions.

The acquisition of AppScotch will allow the group to work on its next major release: an Intelligence product suite with new app advertising metrics to aid marketers in assessing and optimising their marketing and creative strategies.

Commenting on App Annie’s most recent acquisition, Bertrand Schmitt, CEO and co-founder said: “The AppScotch team shares our passion for apps and has developed some exciting complementary technology. App Annie is developing its next wave of innovative products that clients will find invaluable in planning their app development and marketing strategies and this acquisition supports this development.”

Despite speculation that App Annie may be on the verge of going public, Schmitt said the company “definitely” will not be seeking an IPO in 2016.
