The moata goal-based ad engine can't retrofit.
Goal-based bidding across retail-media networks is Perpetua's game. Epinium's edge is different in kind: European by design, human-in-the-loop by default, profit as the objective, and a full platform — not just ads — with listings optimised for the AI assistants reshaping EU discovery.
Beyond goal-based retail media:governed, EU-native, profit-first execution.
Perpetua automates bids toward the goals you set. Epinium combines advertising with governed listing AI, catalog management, and inventory forecasting — profit as the target, and every change on your approval.
EU advertising AI you keep on a leash
- Review, approve, or edit before it goes liveEpinium's AI manages Sponsored Products, Brands, and Display across all EU marketplaces — but proposes changes into a queue. Nothing reaches your account until a human approves it. Perpetua's goal engine acts on its own logic.
- HITL lock on sensitive actionsFlag price changes, high-budget shifts, or bulk edits to pause until a person signs off. You decide where the AI runs free and where it waits — full control, not a fixed ACOS target.
- Full audit trailEvery applied change is logged with author, timestamp, and entity — the governance a rules-based ad platform never surfaces, built in from day one.
Listing AI and GEO — beyond retail media
- AI listing rewriterEpinium rewrites titles, bullets, and backend keywords using real EU search data — driving organic rank gains that goal-based ad buying alone can't deliver.
- GEO for AI shopping assistantsEpinium optimises your listings to rank in Rufus and other AI shopping assistants (GEO) — capturing demand where a growing share of EU buyers now start.
- A+ content generationGenerate A+ modules and brand story content in multiple EU languages with AI — one workflow covering all your marketplaces with no design team required.
Profit intelligence beyond ad metrics
- Unified P&L per ASINSee revenue, ad cost, COGS, and true margin per product — not just ad-platform metrics. Know which ASINs are profitable, not just which hit an ACOS goal.
- TACOS as the north starEpinium steers total advertising cost of sale against real margin, so spend compounds profit instead of chasing an ACOS target across networks.
- Inventory & sales forecastingPredict stockouts before they happen and calculate reorder points from actual sales velocity per EU marketplace — a forward-looking layer Perpetua's ad-focused platform doesn't provide.

ExploreFrequently asked questions
How is Epinium different from Perpetua for EU brands?
Perpetua is a goal-based retail-media platform (US/global, Ascential-owned) strong at automated bidding across Amazon, Walmart, and Instacart. Epinium is purpose-built for Amazon EU, with human-in-the-loop execution, profit-first optimisation, listing AI, and GDPR compliance native to Europe.
Does Epinium keep 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. That's the difference from a rules-only goal engine: you choose which actions need sign-off.
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 retail-media ad engines don't address. Epinium tunes your content for buyers and for the models that recommend to them.
Does Epinium optimise for profit or ad metrics?
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 a standalone ACOS target.
Is Epinium GDPR compliant and built for EU?
Yes. Epinium processes and stores data in Europe, is aligned with the EU AI Act, and is purpose-built for Amazon Spain, Italy, Germany, France, and UK with marketplace-specific AI. It also serves both brands and agencies.
How much does Perpetua cost compared with Epinium?
Perpetua: Essentials $695/mo flat, capped at $10K monthly ad spend; higher tiers custom. 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 Perpetua?
Yes — Epinium. Perpetua — part of the Ascential group, same parent as Pacvue; EMEA reach via the Sellics merger. 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 Perpetua optimise listings for Rufus and AI shopping assistants?
Not documented. 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.
