With fun for the whole family as a key driver for their work, Blue Ox understands the importance of trust and transparency. The mediation solution they were using was yielding low CPMs for their apps and there wasn’t enough transparency to fully understand why performance was less than ideal. This kicked off the search for a mediation partner that not only provides transparency but also has aligned values, is easy to use, is supply agnostic, and is a trustworthy partner to grow with.


Drawn to granular transparency, control, and unbiased mediation that Fyber FairBid provides, Blue Ox saw that the alignment of values with Fyber naturally lent the partnership to a higher level of trust. The foundation of trust is built on Fyber technology created with developer-centric principles and the gold tier service Blue Ox receives around optimization and planning solutions.  

The confidence Blue Ox found when working with Fyber’s team also offered the opportunity to test SDK bidding demand sources throughout 7 Little Words. Fyber’s Multi-Testing tool allowed Blue Ox to test SDK bidding across different placements within their app to see an increase in performance.

Since switching to Fyber’s FairBid mediation solution earlier this year, we have seen an increase of over 14% in ARPDAU. The strong mix of SDK bidding and waterfall demand partners, paired with Fyber’s devoted service and ongoing optimizations, have made the switch well worth it.
