Short answer

Epinium vs Perpetua: the short answer

Perpetua is goal-based advertising automation for third-party sellers on Amazon, Walmart and Instacart — you set a goal, its machine learning runs the tactics — plus integrated growth capital. It is part of Flywheel Digital, owned by Omnicom since January 2024 — a different owner from Pacvue, which belongs to Assembly. Its entry plan is $695/month flat, capped at $10K of monthly ad spend, with no free trial. Epinium is a European platform that spans advertising, listings, catalogue and stock, holds every AI change in an approval queue, optimises listings for Rufus and other AI assistants, and reports profit per ASIN. Pick Perpetua for hands-off 3P ad automation and financing; pick Epinium for governed execution beyond advertising in Amazon EU.

Choose Perpetua if…

  • You want to set a goal and step away — its "create goals, not campaigns" model is built for hands-off 3P advertising.
  • You need working capital fast: Perpetua Capital offers up to £3M in 24 hours via Yardline and Ritmo, inside the platform.
  • You also advertise on Walmart and Instacart in North America and want one 3P-focused ad engine for all three.

Choose Epinium if…

  • A $695/month plan capped at $10K of ad spend does not fit you — and you would rather not pay a percentage of spend on higher tiers.
  • You want to try before you buy: Perpetua publishes no free trial and no annual billing.
  • Advertising is not your only lever — listings, catalogue quality, GEO for Rufus and stock all move your margin too.

What buyers actually said

Public review standing, sample size included.

We have not used Perpetua ourselves, so nothing below is our opinion: every point names the third party that reported it and links to it. Scores come from each product's own G2 page, read on the date shown — with the review count, because a high score on a handful of reviews is not the claim a slightly lower one on hundreds is.

What reviewers say works

  • G2 reviewers rated it easier to set up and administer than Pacvue, and preferred doing business with it overall. G2 reviews ↗

Why EU sellers choose Epinium over Perpetua

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.

Governed AI Execution (HITL)

Every AI change lands in a review queue — you approve, edit, or reject before it reaches your account, with a full audit trail. Goal-based automation optimises on rules alone; Epinium keeps a human in the loop on the changes that matter.

Profit, Not Just ACOS

Amazon's Ads Agent optimises Amazon's revenue. Epinium optimises your profit — no conflict of interest. Every decision is driven by TACOS and true margin per ASIN, not an ACOS target in isolation.

GEO — Rank in AI Shopping Assistants

Epinium optimises your listings to rank in Rufus and other AI shopping assistants (GEO) — the emerging discovery surface a retail-media ad engine doesn't touch.

EU Marketplace Native

Epinium is built for Amazon EU — Spain, Italy, Germany, France, and UK — with localised keyword research and marketplace-specific AI. Perpetua reaches EU through Sellics, but leads with a US-first, multi-network retail-media model.

Listings + Catalog + Inventory

Beyond advertising, Epinium rewrites listings, manages your catalogue, and forecasts stock — one connected operation. Perpetua is built around goal-based ad buying, with these layers outside its core.

European Data & AI Act Aligned

Your data stays in Europe under GDPR and is never used to train AI models without your consent. Epinium is aligned with the EU AI Act — governance native to Europe, not a compliance add-on.

How the moat shows up

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.

Govern

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.

Analyse

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.

Frequently asked questions

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 up to $10K monthly ad spend; Growth $695/mo + % of ad spend above it; Premium custom. Epinium publishes its pricing: Guru from €159/mo, Business €349 and Master €799 — published, not quoted on request. Business and Master also carry an advertising commission that tapers from 5% to 2% with volume, charged only on the ad spend Epinium manages. You can start free with no credit card. Full detail on Epinium pricing. Competitor data verified on 15 August 2026 from public sources.

Is there a European alternative to Perpetua?

Yes — Epinium. Perpetua — US (Portsmouth, NH); part of Flywheel Digital, owned by Omnicom since January 2024. 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.
