Rebuilding a live mediation stack from waterfall to bidding.
The exact revenue movement remains confidential. The architecture, operating problem, and decision sequence do not need to be.
A mature, ads-led mobile games portfolio was operating through waterfall-era assumptions while the market moved toward in-app bidding. Adding more demand without changing the auction structure would have created more configuration, not necessarily better competition.
The mediation layer was rebuilt across AppLovin MAX and ironSource LevelPlay. The work connected bidder coverage, waterfall fallbacks, placement behavior, QA, reporting, and partner ownership so the migration could be judged as one revenue system.
The live portfolio moved from waterfall to bidding without turning the migration into a sequence of isolated network changes. The durable outcome was a new architecture and operating cadence for reviewing auction quality, fill, latency, and player impact together.
A mediation rebuild is not complete when the SDK is live. It is complete when teams can explain where impressions clear, why fallbacks exist, which placements behave differently, and what signal should trigger the next change.
