The abundance of digital content and services makes it impossible for the average mobile user to track the most relevant and valuable digital experiences. Curated environments offering manageable quantities of pre-selected, high quality services are increasingly gaining ground in the mobile world.

Upstream’s portfolio includes 3 kinds of curated environments.

– An Application Store, containing premium, popular titles, along with less known titles of great quality and value for users to explore.

– A Game Portal, operating through a mobile site (html 5) to accommodate non-Smartphone users, including titles such as Tap the Frog, Cut the Rope, Bubble Shooter.

– A Video Portal, providing access to premium entertainment, education, and sports media content.

Our curated environments adapt to the technology standards of each user (handset technology, connectivity quality and speed) to offer the optimal experience even for earlier technology mobile handsets (non-Smartphones) operating in low-bandwidth environments.
