The problem

Your hero products perform.
And the other 240?

Only a fraction of your catalog gets real attention. The rest just runs along. Not for lack of potential, but because no day has enough hours to manage 240 products by hand.

What changes

Three things that are different with CORTUA.

CORTUA unlocks revenue across your entire catalog.

Every product gets its own strategy, not just the heroes. Without more hours for you and your team.

Your expertise steers instead of typing.

Out of day-to-day PPC busywork, into strategy, brand and content.

You stay in control.

You set the guardrails, CORTUA acts within them. Glass box, not black box.

What CORTUA does

Not a tool that only optimizes bids. A system that starts with the product.

01 · StrategyFrom the product

02 · LoopFinds & checks the work

03 · TrustAI for judgment

01 · Strategy

From the product, not the campaign.

CORTUA reads your catalog, identifies each product's lifecycle stage and derives the right strategy and campaign structure from it. The expertise of experienced Amazon strategists lives in the system as code, not as a prompt.

Every product gets the strategy only your top sellers get today. Whether 10 or 1,000 products.

02 · Loop

Finds the work. Checks the result.

CORTUA doesn't wait for a trigger. The system spots anomalies itself, acts within your limits and checks the result against the financial signal. What doesn't work gets rolled back.

CORTUA spots problems and opportunities before they show up in the report. And management improves with every cycle.

AI for judgment, math for the budget.

AI interprets and prioritizes. But no number that has to be exact runs through a language model. Bids and budgets are calculated by a deterministic engine, and every action stays traceable in the audit log.

The scale of a self-directed system, without the black box. Nothing critical happens without your OK.

How CORTUA calculatesHallucination-proof

for judgment

Understands goals and context

Reads reviews, competition, seasonality

Spots opportunities and priorities

Engine

for the numbers

Budgets, bids, forecasts

Allocation across the catalog

Reproducible, with evidence

No language model calculates your numbers.

Deterministic and traceable

How it works in detail

Three interlocking loops.

Strategy & planning

Understands your setup, classifies every product by lifecycle stage and builds the campaign plan from it. Proven strategist know-how, hard-coded.

Management & verification

Analyzes continuously, spots risks and opportunities early and acts on them. Every step is verified against the financial signal. What doesn't work gets rolled back.

Execution

Bids, budgets, pacing. Daily, through a deterministic engine: traceable and reproducible. No number from a language model.

AI sees. Expertise decides. Math calculates. You approve.

Context

Four ways to try it. One that scales.

DIY prompts, PPC tools and autonomous AI agents each solve only one piece. CORTUA covers the whole way.

DIY with ChatGPT & Claude

For individual products, it works. At 200, it becomes manual work: supplying context, checking results, making decisions yourself. The AI loses sight of your goals, and you have to double-check every answer.

PPC tools

They optimize bids, and they do it well. But they assume the right strategy is already in place. Where it comes from remains your problem.

AI agents

They promise autonomy and run off on their own in the morning. You see too late what they decide, and step in only after it has already happened.

CORTUA

Builds the strategy and implements the campaigns. AI where it is strong: interpreting, classifying, suggesting. Deterministic algorithms where budget is spent.

Proven strategies and ongoing management for 10 or 1,000 products.

Who it's for

Who CORTUA is built for.

“

Your PPC tool is no longer enough.

Bid optimization alone isn't enough. What's missing is a strategy per product and a response to market changes. With hundreds of products, you can't do that by hand. CORTUA builds exactly that, and your bids run within it.

“

More products than your team can actively manage.

Everything beyond the top sellers has been running along for months, and the margin there is left on the table. You don't want to hire more people for it, and you certainly don't want a black box over your budget. CORTUA manages the entire catalog, with your approval.

“With several hundred ASINs, you just can't manage everything after the top 10 in detail anymore. Without CORTUA, we would have accepted the status quo.”

FAQ

Frequently asked questions.

What is CORTUA?

CORTUA is an AI-powered Amazon ads system by ADFERENCE. It develops its own strategy for every product, builds the campaigns and manages your account on an ongoing basis. You set the guardrails and approve.

Is CORTUA an autopilot? Do I stay in control?

No autopilot. Every critical change comes to the Command Center for approval, with a diagnosis and evidence. You decide what goes live and how much you hand over. Glass box, not black box.

Does CORTUA replace my PPC tool?

CORTUA can complement or replace your PPC tool. It works one level above: strategy per product, campaign structure and ongoing management that classic PPC tools don't cover.

Does this work for my entire catalog?

Yes. CORTUA manages every product with consistent quality, whether 10 or 1,000, not just the hero products. Exactly the long tail that nobody manages by hand today.

Do I still need a PPC manager?

If you have one, you keep them. CORTUA makes them more valuable, not redundant: away from day-to-day campaign upkeep, toward strategy and brand. And if you don't have anyone today, you get senior-level expertise without having to hire.

Is CORTUA GDPR and EU AI Act compliant?

Yes. CORTUA is GDPR compliant and designed for the EU AI Act, developed and hosted in Germany.
