Fiksu has raised $10 million to expand the growth of its mobile app marketing platform. The second round of funding comes from Qualcomm and Charles River Ventures.

Boston-based Fiksu will use the funds to expand its mobile app user acquisition platform. The company says it has seen a surge in global customer demand and will expand in both Europe and Asia-Pacific. It will drive strategic relationships with agencies and brands.

“Fiksu is hyper-focused on using our outstanding and innovative technology to deliver the best app marketing solution for advertisers,” said Micah Adler, founder and chief executive of Fiksu. “Our accomplishments to date demonstrate our technological leadership. It is a true honor to be backed by investors who are deeply respected within the mobile ecosystem and bring such a distinguished track record of innovation excellence.”

Fiksu for Mobile Apps helps lower the cost of getting new users on both iOS and Android. It does so by focusing on loyal users who repeatedly return to an app and are the most likely to spend money on it. The company operates FreeMyApps, a web-based portal where users can get paid apps for free if they try out apps from others.

To date, Fiksu has raised $17.8 million, and it captures 30 billion actions in mobile apps each month. It uses that data to target ads properly at the right users in real-time.

“There is no question that mobile marketing will be of increasing value to the top-name brands who want to capture their target audience on-the-go,” said Johnny Won, mobile and gaming platform manager of Hill Holiday. “Our partnership with Fiksu ensures the right messages are served to the right audiences on their smartphones or tablets, driving deeper brand loyalty, customer engagement, and revenue-generating transactions — exactly what our clients demand.”

“Fiksu occupies a significant leadership position in the industry through an unparalleled commitment to developing a marketing platform with the smartest optimization algorithms and industry-leading attribution techniques,” said Jon Auerbach, general partner of Charles River Ventures. “We are excited about the rapid progress Micah and team have made in catapulting Fiksu from unknown in 2011 to the epicenter of mobile marketing today. We will undoubtedly see the company scale to new heights again this coming year.”

The company has more than 100 employees and plans to double that this year.
