Today Fluent Mobile, the company that recently secured $5.5M in funding from Charles River Ventures for mobile news delivery, announced a rebranding to Fiksu. Along with the rebrand comes a big pivot into mobile advertising, with the company defining themselves as a new marketing technology company.

Fiksu’s initial solution, Fiksu for Mobile Apps, helps brands build their app user bases across carriers and devices in a highly cost effective way. Dubbed the mobile industry’s first user acquisition platform, the company has already locked down initial customers including Groupon, Barnes & Noble, Gilt Groupe, Hearst, VH1, and Boston-based local discovery app WHERE.

As we’ve discussed here at BostInno before, the increased number of apps released and available to users has made climbing the ranks in app stores for developers much more difficult. But climbing those ranks, as Boston’s RunKeeper knows well, is a sure and steady way to increase your user base — fast. Fiksu helps with this by optimizing traffic across the entire mobile ecosystem — ad networks, real-time bidding systems, download networks, etc. According to the company, their technology and algorithms results in “radically improved app store visibility combined with substantially improved organic download activity.”

Says who? You may be thinking. One of the company’s earliest customers, the Tunewiki app, offered, “Fiksu proved to be a successful way to invigorate our established app and helped us reach No. 10 overall. It helped us get more than we imagined possible for our mobile promotion spend and also provided unique insights for future app launches.”

Fashion flash boutique behemoth Gilt Groupe also sings praise. “The experts at Fiksu have been a valued partner for us as we rapidly expand our mobile business and navigate the complex mobile app market,” said Jason John, Gilt’s senior director marketing.

Fiksu’s proprietary algorithms include “embedded app store behavior insights” and a “real-time allocation engine.” The platform has already amassed mobile data and app usage data from over 44 million downloads and more than 1 billion app launches yielded from those downloads.

As for the cost of using Fiksu to drive downloads (aka acquire users) to your mobile app, the company reports an average loyal user acquisition cost of less than $1 per user — and sometimes half that per user.

“Fiksu takes the guesswork out of mobile app marketing and replaces it with proven results – cost-effective downloads and usage,” said Fiksu CEO, Micah Adler. “Mobile marketers no longer have to hedge their bets on fragmented mobile ad spends and strategies. With Fiksu, they now have the most cost-efficient route to securing engaged, repeat app users.”
