Epinium vs Quartile: the short answer
Quartile is a retail media optimisation platform: it automates advertising across Amazon Ads, Amazon DSP, Walmart, Instacart, Criteo, Google and Meta, and reports on ROAS. Epinium is a European platform that goes past advertising — AI proposes changes to bids, listings and stock, your team approves each one before it reaches Amazon, listings are optimised to rank in Rufus and other AI assistants, and the objective is profit per ASIN (TACOS, COGS, margin) rather than ad ratio. Pick Quartile for multi-channel ad breadth; pick Epinium for governed execution, EU depth and profit.

Choose Quartile if…
- Your priority is one ad console across retail media and D2C at once — Amazon DSP, Walmart, Instacart, Criteo, Google, Meta and Microsoft Ads.
- You want a managed-service feel: Quartile pairs the platform with a dedicated account team on every plan.
- Advertising is the only workflow you need to centralise — listings, catalogue and stock stay with other tools.

- You will not let AI touch your account unsupervised: every change waits in an approval queue with a full audit trail.
- You sell across Amazon EU (ES, IT, DE, FR, UK) and want localised keyword data plus EU data residency and AI Act alignment.
- You measure success in margin, not ACOS — and you want listings ready for Rufus and other AI shopping assistants.

The moatQuartile can't copy.
Advertising automation is a commodity. Epinium's edge is structural: European by design, human-in-the-loop by default, profit as the objective, and listings optimised for the AI assistants that now shape Amazon discovery.
From ACOS automation togoverned, profit-first execution.
Quartile's AI adjusts bids to hit an ad ratio. Epinium's AI proposes changes across advertising, listings, and inventory — you govern what goes live, profit is the target, and your listings are tuned for the AI assistants buyers now trust.
Every AI change passes through your approval
- Review, approve, or edit before it goes liveAI drafts the change — a bid, a budget shift, a listing edit — and holds it in a queue. Nothing reaches your Amazon account until a human signs off, so autonomy never becomes a runaway.
- HITL lock on sensitive actionsFlag price changes, high-budget campaigns, or bulk edits to pause until a person approves. You choose exactly where the AI runs free and where it waits.
- Full audit trailEvery applied change is logged with author, timestamp, and the entity it touched — a complete record of what the AI did and who approved it.
Listings tuned for organic rank and AI assistants
- AI listing rewriterEpinium rewrites titles, bullets, and backend keywords using competitor analysis and real search data — capturing organic growth that ad optimisation alone can't reach.
- GEO for AI shopping assistantsEpinium optimises your listings to rank in Rufus and other AI shopping assistants (GEO) — positioning your products where a growing share of buyers now start their search.
- Keyword index monitoringTrack which keywords each ASIN is indexed for across every marketplace. Spot ranking gaps and fix listings proactively before position erodes.
Profit intelligence, not advertising KPIs
- Unified P&L per ASINSee revenue, ad spend, COGS, and true margin per product — the profit view Quartile's ACOS-first reporting leaves out. Real business outcomes, not just advertising ratios.
- TACOS as the north starEpinium steers total advertising cost of sale against real margin, so growth compounds profit instead of buying revenue at any ACOS.
- Inventory & sales forecastingPredict stockouts before they happen and calculate reorder points from actual sales velocity per marketplace — a forward-looking layer Quartile doesn't provide.

ExploreFrequently asked questions
How is Epinium different from Quartile?
Quartile is an advertising automation engine focused on ACOS. Epinium is a European platform where AI proposes changes across advertising, listings, and inventory, your team approves what goes live, and profit — not ad ratio — is the objective.
Does Epinium put a human in the loop?
Yes. Every AI change lands in a review queue — you approve, edit, or reject before it reaches your account, with a full audit trail. You decide exactly which actions require sign-off and which the AI can run autonomously.
What is GEO and does Epinium do it?
GEO is optimising your listings to rank in Rufus and other AI shopping assistants — a discovery surface pure advertising tools ignore. Epinium tunes your content for shoppers and for the models that now recommend products to them.
Does Epinium optimise for profit or ACOS?
Profit. Amazon's Ads Agent optimises Amazon's revenue; Epinium optimises your profit — no conflict of interest. Decisions are driven by TACOS and true margin per ASIN, not vanity ACOS.
Is Epinium built for Amazon EU?
Yes. Epinium is purpose-built for Amazon EU — Spain, Italy, Germany, France, and UK — with marketplace-specific AI, localised keyword data, GDPR compliance, and alignment with the EU AI Act.
How much does Quartile cost compared with Epinium?
Quartile: Not published — quote after a demo. Epinium publishes its pricing: Guru from €159/mo, Business €349 and Master €799 — always a flat subscription with no percentage of your ad spend, so your bill does not climb as you scale investment. You can start free with no credit card. Full detail on Epinium pricing. Competitor data verified on 24 July 2026 from public sources.
Is there a European alternative to Quartile?
Yes — Epinium. Global retail media platform — 5,300+ customers across 32 countries. Epinium is a European company with data held in the EU under GDPR, aligned with the EU AI Act, and purpose-built for Amazon EU — Spain, Italy, Germany, France and the UK — with keyword data localised per marketplace rather than a translated engine.
Does Quartile optimise listings for Rufus and AI shopping assistants?
Not documented on its site. Epinium does: it optimises your listings to rank in Rufus and other AI assistants (GEO), writing content for the shopper and for the models that recommend to them — see GEO / AI search. To be precise: Epinium optimises for that surface; it does not measure your share of voice inside Rufus.
