Twelve criteria, both columns sourced and dated, plus what G2 reviewers said when they compared the two directly. No sponsored placements and no affiliate links.
Perpetua if you want a price you can evaluate today and hands-off Amazon automation; Quartile if your retail media plan already runs past the marketplaces and you want people attached to it. Perpetua and Quartile both automate retail media, but they meet the buyer at opposite ends of the sales process. Perpetua puts its price on the page — $695 a month for Essentials while you are under $10,000 of monthly ad spend, then a percentage of spend above it — and sells goal-based automation to third-party sellers and challenger brands on Amazon, Walmart and Instacart, with growth capital attached. Quartile publishes no price and starts with a demo, but spreads across more channels and more customer sizes: 5,300+ customers in 32 countries, Amazon Ads and DSP plus Walmart, Instacart, Criteo, Google, Meta and Microsoft, with a dedicated account team on every plan. On G2 Quartile rates 4.6 from 215 reviews against Perpetua's 4.4 from 79, and neither publishes a free trial.

Two paragraphs, no adjectives from us — what the product does and who it is sold to.
Perpetua is goal-based advertising automation for Amazon, Walmart and Instacart. You set a target and its machine learning runs the bidding and keyword tactics to reach it, with hourly intraday adjustment on higher tiers. It also bundles growth capital, a financing product. Entry is $695 a month while monthly ad spend stays under $10,000, then a percentage of spend on top.

The cost row is our arithmetic on the figures each vendor publishes, at a common $25,000 of monthly ad spend. It is an estimate for comparison, not a quote from either company.

Almost every comparison of these two is written for a US seller. Here is what each one publishes about the European marketplaces, where your commercial data sits, and which currency you are billed in.
Neither product is better in the abstract. Here is the case for each, on the criteria that decide it.
The rows below are the ones where Epinium ships a capability and neither Perpetua nor Quartile documents one. Anything either of them already does is not on this list.

ExploreIf Amazon is your only channel, Quartile's advantage — Criteo retailers, Google, Meta, Microsoft — is spend you are not making. Perpetua concentrates on Amazon, Walmart and Instacart and publishes an entry price you can evaluate today. The caveat is the $10K monthly ad-spend ceiling on Essentials: cross it and you move to a percentage of spend.
Neither publishes a free trial. Perpetua's pricing page lists no trial and no annual billing; Quartile routes you to a demo request. Epinium is free to start with no credit card, so you can connect an account and see the platform against your own data before any commercial conversation.
Yes — Epinium. Both Perpetua and Quartile are advertising platforms: the listing, the catalogue and the stock sit outside what they document. Epinium runs advertising, listing rewriting including GEO for Rufus, catalogue control and inventory forecasting in one platform, with human approval before any AI change reaches Amazon and a P&L per ASIN behind the decisions.
Epinium. Against Perpetua (Essentials $695/mo up to $10K monthly ad spend; Growth $695/mo + % of ad spend above it; Premium custom) and Quartile (Not published — quote after a demo), Epinium publishes its pricing: Guru from €159/mo, Business €349 and Master €799, plus an advertising commission that tapers from 5% to 2% with volume and applies only to the spend it manages. It also goes past advertising — listings, catalogue, stock and per-ASIN P&L — with human approval before AI touches your account. Detail on Epinium pricing. Both competitors' data verified on 15 August 2026 from public sources.
Perpetua: Not documented. Quartile: Not documented on its site. Epinium does optimise your listings to rank in Rufus and other AI shopping assistants — see GEO / AI search. To be precise: Epinium optimises for that surface; it does not measure your share of voice inside it.
