Ad Mediation Platform for Mobile Apps & Games

What Is Ad Mediation and Why It Matters

Managing ad monetization means wrestling with a mess of SDKs, dashboards, and reporting formats from every ad network. Ad mediation cuts through that noise. It sits between your app and every network, sending each impression straight to the highest bidder.

Without an ad mediation platform, you’re stuck maintaining separate waterfall setups, manually adjusting floor prices, and losing revenue to inefficient auctions. Every hour you spend on that is an hour not spent building your game.

CAS.AI handles this differently. Our mobile ad mediation runs a hybrid RTB + waterfall auction for every single impression: 1M+ bid requests per second across 20+ ad networks and 150+ DSPs. The result: the highest price for every impression, in every geo, in every format.

Why Independent Ad Mediation Wins

Many ad mediation platforms are run by companies that also operate their own ad networks. CAS.AI takes a different approach: an independent auction where every network competes on equal terms for each impression.

CAS.AI doesn't own an ad network. We don't sell demand. We only make money when you do. Every auction on our ad mediation platform is transparent: RTB bids go head-to-head with waterfall, and you see exactly who won and at what price, every time.

This isn't theoretical. Developers who switch from closed mediation platforms to CAS typically see a 1.5-2x increase in ARPU - not because we have magic algorithms, but because open competition among demand sources yields better prices. It's basic economics applied to ad mediation solutions.

Our SDK processes 1 million bid requests per second across 150+ DSPs and 20+ top ad mediation networks. Every ad format is optimized at the impression level: rewarded video, interstitals, banners, MRECs, and native ads. We support programmatic ad mediation through RTB alongside traditional waterfall - a hybrid approach that captures the best of both. This includes full support for video ad mediation across rewarded and interstitial video formats, as well as the complete ad mediation network ecosystem.

When you earn, you get paid. Fast. CAS pays out from day five, including crypto. No more waiting months for your money.

FAQ: Ad Mediation with CAS.AI

Got Questions About Ad Mediation? CAS.AI Has Answers.

What is ad mediation?

Ad mediation is a technology that lets app developers manage multiple ad networks through a single SDK. Instead of integrating each network separately, an ad mediation platform sends ad requests to all connected networks and selects the highest-paying ad for each impression. This maximizes your eCPM, fill rate, and total revenue.

What ad formats does CAS support?

All major mobile ad formats: rewarded video, interstitial (static and video), banner, MREC (300×250), and native ads. Every format is optimized per-impression through our hybrid RTB + waterfall engine - making CAS the best mobile ad mediation choice for apps across all categories.

Does CAS support programmatic and video ad mediation?

Yes. CAS is built on a hybrid RTB plus a waterfall engine, making it a full programmatic ad mediation solution. Every impression goes through a real-time auction across 150+ DSPs, including video-specific demand partners. Video ad mediation, both rewarded and interstitial, is one of CAS's strongest formats, consistently delivering top eCPMs for mid-core and casual game developers.

How does ad mediation for Unity work with CAS?

CAS offers a native Unity SDK that replaces all individual ad network plugins in your project. Integration takes under 30 minutes: import the CAS Unity package, configure your ad formats in the dashboard, and you're live. Ad mediation for Unity via CAS supports rewarded video, interstitials, banners, and MRECs, all managed through a single, lightweight SDK with no manual waterfall tuning required.

Is there an SDK for ad mediation in Flutter and React Native?

Yes, CAS provides official packages for both. Ad mediation for Flutter and ad mediation for React Native are fully supported, with the same single-SDK model as our native iOS/Android integration. You get access to the complete ad mediation network stack (20+ networks, 150+ DSPs) without writing platform-specific bridge code. Setup guides and sample apps are available in our docs.

Can I use CAS for ad mediation in Godot or Unreal Engine?

Absolutely. CAS supports ad mediation for Godot and ad mediation for Unreal Engine via dedicated plugins. These are designed for game studios shipping on mobile who need a reliable, high-performance ad mediation platform without leaving their game engine workflow. Both plugins support all major ad formats and connect to the same competitive RTB auction powering the rest of the CAS network.

What makes CAS one of the top ad mediation platforms for indie and mid-size studios?

Most top ad mediation platforms are built around a network they own, which means their "mediation" is really just a funnel for their own inventory. CAS is fully network-neutral. Our ad mediation solutions are designed to maximize your revenue, not ours. We provide transparent reporting, a no-loss A/B testing guarantee, and access to the broadest demand pool available, making CAS the best mobile ad mediation choice for studios that want results without lock-in.

What is the no-loss guarantee?

Run an A/B test comparing CAS against your current app mediation setup. If CAS earns less, we pay the difference. You cannot lose money by testing us. This applies to any app with 5,000+ daily active users.

How long does integration take?

Most developers complete CAS SDK integration in under 30 minutes. We support Unity, Flutter, React Native, Godot, and Unreal Engine. One SDK replaces all individual network SDKs - that's the power of ad mediation done right.

Can I use CAS alongside another mediation?

Yes. Many developers start by assigning 20% of traffic to CAS while keeping their current platform on 80%. Once CAS proves higher revenue, they gradually shift. No disruption to your existing app mediation setup.

What ARPU improvement can I expect?

Developers who migrate to CAS typically see x1.5-2x ARPU growth. Our system processes 1M+ bid requests per second, finding the best price for every impression. Results vary by app and geo - that's why we encourage a real A/B test.

Take the next step. Run a free A/B test with CAS on 20% of your traffic today. If CAS doesn't outperform your current setup, we'll pay the difference. Experience the impact firsthand.
