Mediation shouldn't mean compromise.
We started ApexMediation as ad engineers who were tired of mediation platforms that weren’t built for publishers.
Our story
We built ApexMediation after years of watching legacy mediators erode publisher trust: hidden algorithms, opaque fees, and networks that couldn’t be removed. That integration tax made switching feel like rebuilding from scratch.
We believed there had to be a better way—one where the publisher retains control of every network relationship, where auctions are auditable, and where the mediation layer is a tool, not a gatekeeper.
Today, ApexMediation is built alongside design-partner studios who demand transparency, reliability, and the flexibility to run their ad stack their way.
What we believe
Our values aren't just words on a wall—they're built into every line of code.
Transparency
Every auction is verifiable. You never wonder if you're being treated fairly.
Publisher control
You bring the networks, you set the rules. We don't gatekeep.
Privacy-first
No fingerprinting, no secret sharing. Your users' data stays in your hands.
Reliability
99.9% uptime with decision latency p95 <200ms. We treat downtime as seriously as you do.
Transparency → Signed auction logs Control → Your networks, your payouts Privacy → No fingerprinting Reliability → Rollback & SLOs Every principle is code, not just copy.
