Custom Ad Server
GAM takes 10-20% of gross revenue. At $25M+ that is millions going to Google every year — in a system where they also control your data.
We build the ad server for publishers who have outgrown what Google Ad Manager can handle — financially, commercially, or both. You own the platform. No rev-share. Full bid-level data. Deal structures built for your business model.
The problem
GAM lock-in costs more than the platform fee
Google Ad Manager charges a rev-share on gross revenue. At scale that number is not a small line item. For a publisher doing $25M in ad revenue, you are sending $2.5M to $5M to Google every year to use their ad server. Not for demand. Not for buyers. For the pipes.
The data problem is just as serious. GAM controls what data you see. Bid-level logs, auction results, losing bids — that data sits inside Google's infrastructure. What you get is aggregated reports in GAM's format. Your team is making pricing decisions without the full picture.
Then there are the business model constraints. Sponsorships, share-of-voice guarantees, content-integrated pricing — GAM was not built for these. Publishers force-fit their commercial models into GAM's structure and leave revenue behind in the process.
Common question
Why not just use an open source ad server?
Open source ad servers like Revive exist, and they are free to download. But free to download is not the same as ready to use. You still need hosting, infrastructure, security hardening, and ongoing maintenance. The licensing cost is zero. The engineering cost is not.
More importantly, open source ad servers are built for general use cases. They do not have publisher revenue logic, bid density analytics, or custom deal structures built in. You get the base, and then you build everything your commercial model actually requires — which is the same amount of work as building a custom server, without the publisher-specific foundation.
What we build is scoped to your inventory structure, your deal types, and your data requirements from the start. Not a generic codebase that someone has to extend.
What we build
Publisher-owned ad server, scoped to your stack
Not a white-label product. Not an open source fork. We build to your inventory structure, your deal types, and your data requirements. Full source code delivered. No ongoing platform fees.
Bid-level data ownership
Every bid, every auction, every impression — fully logged and owned by you. Not a summarized report from a platform that controls what you see. Full access to raw bid data lets your team make real pricing decisions.
Custom deal structures
Sponsorships, guaranteed deals, share-of-voice buys, content integration pricing — deal types that GAM cannot support natively without workarounds. Built to your commercial model, not Google's.
Floor pricing engine
Dynamic floor pricing tied to your actual bid density data. Not GAM's limited floor controls. Set floors by advertiser, audience segment, placement, or deal type — and see exactly how floors affect fill rate and CPM.
GAM hybrid or full replacement
We build for your current stack. Full GAM replacement for publishers ready to move, or a hybrid model that routes high-value inventory through your custom server while keeping programmatic on GAM. You choose the path.
Business outcomes
What changes after you own the ad server
10-20%
GAM rev-share eliminated
Google Ad Manager charges 10-20% of gross revenue as a platform fee. At $25M in ad revenue, that is $2.5M-$5M going to Google annually. A custom ad server eliminates that cost entirely.
100%
Bid-level data access
GAM gives you aggregated reporting. A custom ad server gives you full bid-level logs — every auction result, every losing bid, every floor breach. That data is the foundation for real yield optimization.
Custom
Deal types GAM cannot handle
Publishers with complex commercial models — sponsorships, guaranteed share-of-voice, branded content pricing — hit GAM's structural limits. A custom server is built around your deal types, not Google's.
Zero
Platform lock-in
You own the code. No vendor dependency, no platform risk, no rev-share creep. If Google changes pricing or policy, it does not affect you. You control the infrastructure.
Who this is for
Publishers where GAM cost has become a real number
Primary fit
Large Publishers — $25M-$100M ad revenue
At this revenue level, GAM rev-share is a seven-figure line item. The ROI on a custom ad server is clear. Publishers here also tend to have the complex deal types and data requirements that make a custom build worth doing properly.
Secondary fit
Medium Publishers — $10M-$25M ad revenue
Publishers in this range who are hitting GAM's business model limits — not just the cost — are the right fit. If the constraint is deal type flexibility or data access, the case for a custom server holds before $25M.
Not the right fit: publishers under $10M in ad revenue where the build cost does not recover against the rev-share saved. The right answer there is GAM optimization, not replacement.
Proof point
Pricing control platform for a Fortune 50 media company
Advantrix Labs built a pricing control and ad management platform for a Fortune 50 media company — the kind of publisher-revenue infrastructure that GAM cannot support natively. The platform gave the ops team full control over floor pricing, deal structures, and delivery data across multiple inventory types. Delivered as owned infrastructure with no ongoing platform fees.

Stop paying Google for the pipes.
We scope the ad server to your inventory structure, deal types, and data requirements. Build starts once scope is locked. You own everything that ships. No rev-share, no lock-in, no ongoing platform fees.
