Fyber and LifeStreet team up to drive success for UA marketers with MRAID and video ad formats


Fyber Marketplace has direct access to top-ranking mobile app publishers, scale, and serves ads across formats. Fyber recognized that over the years, video and MRAID had become a growing portion of performance advertisers’ spend and were now essential formats for app install campaigns. As it wanted to attract even more premium buyers to its portfolio of demand partners, Fyber needed to help marketers optimize their acquisition funnel across MRAID and video.


Seeking to update their SDK, Fyber selected LifeStreet as a Q&A partner for the process. With a clearly defined strategy, test scenarios, and a strong feedback loop, LifeStreet was able to help Fyber understand the technical impact of any SDK updates they made in order to comply with VAST and MRAID requirements. As a result, Fyber was able to quickly and effectively troubleshoot integration glitches and SDK bugs.

Fyber and LifeStreet are two companies motivated by delivering excellent technology that drives the best results to ensure our partners’ success. Because LifeStreet treated our SDK update like their own project, we were able to help each other help our clients capitalize on growth trends. LifeStreet was more than a technical partner. They were a vital part of the development process.


The strong technical relationship between Fyber and LifeStreet helped Fyber develop a world-class SDK with a video player that seamlessly delivers and measures high-impact video creatives. In turn, LifeStreet is able to drive strong results for its advertisers’ investments with video through Fyber Marketplace.
