One mediation layer. Your networks. Your rules.
ApexMediation is the neutral orchestration layer between your apps and your ad networks, with SDKs tuned for reliability and a console built for serious teams.

BYO: Bring Your Own demand.
Managed demand bundles networks under one vendor. BYO mediation keeps you in charge of your ad relationships—ApexMediation handles the infrastructure.
- You own all ad network accounts, contracts and payouts.
- ApexMediation never arbitrages or resells your demand.
- Our adapters and S2S integrations are built to be network-agnostic.
- You can swap networks in and out without touching our commercial terms.

Cryptographic transparency.
Each auction produces a tamper-evident record: bids, waterfall order, floors, and the winning decision. These records are hashed and signed.
Verifiable auction logs
Export log-level auctions to your data warehouse and tie each impression back to a signed record.
Dispute-ready evidence
When reconciling with networks or partners, you have more than screenshots. You have cryptographically signed logs showing what your mediation layer actually did.
Data-warehouse friendly
Streaming schema is documented and stable, so you can wire ApexMediation into BigQuery or export to object storage (S3/GCS) for your existing tools.
Migration Studio.
Most teams stay on their existing mediation for one reason: fear. Migration Studio is built to reduce that fear.
- Import your existing placements and waterfalls.
- Simulate auctions with your current rules vs ApexMediation.
- Enable ApexMediation per-placement, with instant rollback.
- Track results over time with side-by-side reports.
Result: you never have to "flip the big switch" all at once.

| Feature | ApexMediation | Legacy Mediators |
|---|---|---|
| Keep your ad network contracts | Sometimes | |
| Signed, verifiable auction logs | No | |
| Per-placement gradual migration | Rarely | |
| Per-adapter circuit breakers | No | |

SDKs that just work.
We design the ApexMediation SDKs to be predictable, well-behaved citizens of your app.
Android & Android TV
- Background-only network I/O and disk access
- StrictMode fatal in debug builds to catch violations early
- Circuit breakers and timeouts per adapter
- Lightweight footprint and well-documented ProGuard/R8 rules
iOS & tvOS
- async/await-based API surface
- MainActor limited to UI work only
- Config signature verification and safe fallbacks
- Extension-safe guards
Unity
- IL2CPP and Mono support
- Clean C# API with native bridges hidden away
- Debug overlay for placements and adapter status
Web
- TypeScript SDK with strict types
- No surprises in how events are fired or batched
For CTV & Web Video: SSAI that's debuggable
Server-side ad insertion should be deterministic and auditable. ApexMediation provides full visibility into every ad decision.
Deterministic behavior
Same inputs produce same outputs. Reproduce any ad decision with the exact context.
Explainable traces
Every SSAI decision includes a full trace: waterfall order, bid responses, winner selection.
Signed evidence
Cryptographically signed logs for every insertion. Dispute-ready documentation.
Safe-mode & rollback
Automatic fallback to safe configurations. Instant rollback if guardrails trigger.
See exactly what your mediation is doing.
- Per-adapter latency, fill, error and timeout metrics.
- SLOs and alerts for auction deadlines and error rates.
- Mediation debugger with sanitized request/response timeline.
- Supply chain tools: app-ads.txt and sellers.json inspector.
- Fraud and quality dashboard (shadow-mode ML, if enabled).
