Perpetua vs Teikametrics (2026): The $695 Floor Against the 3% Formula

Short answer: these two Amazon ad platforms are separated by a factor of about four at the entry point and by one clause in the middle. Perpetua publishes Essentials at $695/month for up to $10K in monthly ad spend; Teikametrics publishes Essentials at $149/month billed annually, or $179/month billed monthly, for the same $10K band (perpetua.io/pricing and teikametrics.com/pricing, both data checked 2026-09-01). Above $10K of spend both switch to a base fee plus a percentage — but Teikametrics prints its number, “+3% of ad spend over $10K”, and Perpetua prints only “+ % of ad spend”. Perpetua’s own Terms of Service define where that number lives, and it is not on any public page. This comparison prices both, reads both contracts, and separates the two products by ad channel rather than by marketing copy.

Published pricing, side by side

Sources: perpetua.io/pricing and teikametrics.com/pricing , both data checked 2026-09-01. Perpetua’s figures are unchanged from our previous check on 2026-08-24, and Teikametrics’ from 2026-08-15.

Three readings follow from that table. First, the floor. A seller at $8K of monthly ad spend pays Perpetua $8,340 a year and Teikametrics $1,788 a year on the annual rate — the same ad-spend band, a $6,552 difference. Second, the ceiling on the published information. Both vendors stop publishing at the tier where the percentage begins, but Teikametrics stops later, because it at least names the rate. Third, the trial. Teikametrics lets you see the product before signing; on 2026-09-01 Perpetua’s pricing page contained no offer of a trial, free or paid, and no self-serve checkout.

The percentage clause, read from each vendor’s contract

This is the part of the bill that neither pricing page settles, so we read the terms instead.

Perpetua’s Terms of Service (perpetua.io/tos , “Last Updated: May 26, 2026”) define the fee structure but publish no rate. Verbatim: “Managed Ad Fees the percentage specified on the Order Form of the Media Costs on display and video advertising placed on or through the Services during each calendar month of the term of the Contract”. The monthly component is defined the same way — “Monthly Fee means any minimum charge for use of our Services specified in the Order Form” — and the umbrella definition reads “Fees means the Managed Ad Fees, the Media Fees, the Minimum Media Fee, the Monthly Fee or any other fee specified on the Order Form.”

Two things in that language matter to a buyer. Every number is deferred to an Order Form you cannot see before you are in a sales conversation. And the percentage, as defined, attaches to display and video media costs, not to all advertising — the pricing page’s shorter phrase “% of ad spend” is broader than the contract’s own definition. If display and video are not where your spend sits, that gap is worth resolving in writing before you sign, in either direction.

Teikametrics takes the opposite approach on the rate and a similar one on the basis. Its pricing page prints “+3% of ad spend over $10K” on both Advanced and Enterprise (checked 2026-09-01). What it does not resolve is whether the 3% applies to the whole spend or only to the portion above $10K, and what the Advanced base fee is; our Teikametrics review documents that gap and prints no figure for the base, because none appears on the site.

The practical difference: with Teikametrics you can model a worst case from public information and negotiate the base. With Perpetua you cannot model anything above $10K without a quote. Neither is a scandal — enterprise ad platforms price this way — but only one of them lets you do arithmetic before the call.

Two different products under similar claims

Both vendors sell goal-based bid automation. The published feature lists diverge on what surrounds it.

Perpetua’s Essentials list is advertising-shaped: “AI-powered bid optimization,” “Automated keyword harvesting,” “In-depth performance & profitability reporting,” “Data-driven performance recommendations,” plus onboarding webinars, chat support, a Slack community and the Perpetua Ad School video library. Growth adds the things that justify its percentage: “Hourly Reporting & Intraday Optimization via Amazon Marketing Stream,” “Hourly Share-of-Voice and Organic Rank insights,” “Revenue opportunity analysis & competitor search term data,” and access to Perpetua’s Client Success team with tailored onboarding, 3- and 6-week check-ins and business reviews on request (perpetua.io/pricing, checked 2026-09-01).

Teikametrics’ list is wider than advertising. Every tier starts with the same line — “ARI strategic suite: Ads, Catalog, Inventory, Insights” — and every tier includes “Refunds Recovery.” Advanced adds “Advanced ad channels: Amazon DSP & Walmart Onsite Display,” “Integrated Amazon Marketing Cloud (AMC),” dedicated onboarding, profitability dashboards, search dashboards and templates, and the option to add Managed Services (checked 2026-09-01).

So the two products answer different questions. Perpetua’s paid surface is depth on Amazon advertising, with intraday optimization as the headline. Teikametrics’ paid surface is breadth across Amazon and Walmart, with catalog, inventory and refunds attached to the same subscription. A seller who is Amazon-only and spends heavily on Sponsored ads is buying different value from a seller running two marketplaces who wants one bill for ads and operations.

Where the brand names came from — and the Flywheel collision

Both names carry history that turns up in older reviews, and one word appears on both sides meaning two unrelated things.

Perpetua absorbed Sellics. Sellics GmbH was acquired on 19 April 2022 and merged into Perpetua; sellics.com now redirects to perpetua.io, and Perpetua’s own site footer still carries a page titled “Sellics joins forces with Perpetua” at /sellics-joins-perpetua/ (footer seen 2026-09-01). If you are comparing against a Sellics quote, note that the old Sellics bill scaled with Amazon revenue and topped out well under $400/month, against Perpetua’s $695 floor — our Sellics alternatives page works through what survived the merger and what did not.

Perpetua’s corporate parent is not named on its pricing or About pages, but it is named in its privacy policy. That document, “Last updated on 06 August 2025,” opens: “This global privacy policy explains how Flywheel Digital Limited and/or its affiliates (“Flywheel” referred to as “we”, “us” or “our”) handle your personal data” (perpetua.io/privacy , checked 2026-09-01). The postal contact given in the same policy is “Write to us at Omnicom Group Inc. Attn: General Counsel 280 Park Avenue New York, NY 10017,” and the Careers link in the site footer points to an Interpublic-hosted Workday tenant for OMC. The contracting party in the Terms of Service is a different name again: “Perpetua, we, us, our means Perpetua Labs, LLC. or the Perpetua Affiliate identified on the Order Form.” For a buyer this is procurement detail rather than product detail, but it is the kind of detail that decides which entity your MSA names.

Teikametrics has its own Flywheel, and it is not that one. The platform Teikametrics sold for years as “Flywheel 2.0” is now marketed as ARI, or Artificial Retail Intelligence; /flywheel/ redirects to /platform/ while the sign-up flow still names Flywheel 2.0 (checked 2026-08-15, documented in our review). The two uses of the word are unrelated: one is Teikametrics’ own product brand, the other is the corporate entity that publishes Perpetua’s privacy policy. Search results conflate them, and older comparison articles inherit the confusion.

Contract and exit terms

Neither vendor sells a cancel-anytime subscription above the entry tier, and the mechanics differ.

Perpetua, clause 2.3, verbatim: “If the Order Form provides for auto-renewal, the Contract will automatically renew unless either party provides the notice period specified in the Order Form prior to expiration.” The renewal behaviour, the term length and the notice window are all deferred to the Order Form, so there is no public answer to “how do I leave?” — only a public answer to “where is that written?”

Teikametrics publishes the mechanic. From teikametrics.com/terms-conditions , section 4, verbatim: “The Initial Term of each applicable Order shall automatically renew for additional periods of the same length (each a “Renewal Term”) until Customer notifies Company in writing (email to suffice) that it does not wish to renew and such notice is made at least fifteen (15) days prior to the end of the then-current Term” (checked 2026-09-01). Fifteen days, in writing, email accepted.

That asymmetry is worth a line in your notes: Teikametrics tells you the notice period before you sign; Perpetua tells you which document will tell you.

What the public review record says

Neither set of complaints below is ours, and neither is verbatim. These are third-party review summaries collected in our research corpus from public G2 listings; individual post dates were not captured, so they carry no date stamp and are reported as themes rather than as quotations.

For Perpetua, reviewers describe a system that is slow to learn and weak on seasonality, results that compared unfavourably with manual campaign management, and account-manager guidance to increase spend so the model could learn faster — a complaint that reads differently once the Growth tier’s percentage is in the picture. Others describe account managers leaving during onboarding, and a promised Target/Criteo integration being cancelled after they had signed for it.

For Teikametrics, the themes are a serious profitability complaint from at least one reviewer, an interface that requires scrolling in two directions on the detail screen, no Google advertising inside the platform, and a genuine learning curve in translating goals into bid behaviour. Our Teikametrics review carries a dated, verbatim Trustpilot complaint about the gap between the published entry price and an actual quote.

Treat all of it as the reviewers’ accounts of their own experience. We did not audit any account.

Scorecards

Scores use the 8-dimension rubric applied across this site, based on published documentation, pricing pages and public reviews rather than a controlled benchmark. Out of 5.

Where they tie. Both take 5 for Depth and Automation: intraday optimization against Amazon Marketing Stream on one side, an ads-plus-catalog-plus-inventory surface with DSP and AMC on the other, both running bids unattended against goals you set. Both take 2 for Pricing, for the same structural reason — the bill stops being computable from public information at exactly the point where most buyers’ spend sits.

Where they separate. Perpetua scores higher on Team Fit and Support because named human help — Client Success team, tailored onboarding, scheduled check-ins — is published on a plan rather than reserved for a quote, and its entry tier includes chat support where Teikametrics’ includes email. Teikametrics scores higher on Stage Fit for the plain reason that a Growth-stage seller can actually buy it: $149/month is reachable at $5K of ad spend, and $695 is not.

Who each one is built for

Choose Teikametrics if you sell on both Amazon and Walmart, want catalog, inventory and refunds recovery under one subscription, are under or near $10K of monthly ad spend, or need to see the product before committing. It is the only one of the two you can trial, price and cancel using published information.

Choose Perpetua if your spend is well past $10K, Amazon Marketing Stream-driven intraday optimization is the specific capability you are buying, and you want a named client-success contact attached to the plan. Have the Order Form define the Managed Ad Fees percentage, its basis, the term and the notice period before you sign — the Terms of Service confirm that all four live there and nowhere else.

Choose neither if you are spending under about $3K a month on ads, where even $149 is a meaningful share of spend before Amazon takes a cent. Scale Insights and m19 sit closer to that range on fee shape, and the Amazon PPC and advertising hub scores the wider category.

One line item that moves at the exit. Refunds Recovery is bundled into every Teikametrics tier, so leaving the platform also removes it; Perpetua’s published plans never included it. Among independent replacements, ReimburseOps runs a Free $0 plan showing 3 flagged records in full and a Pro plan at $19/month, and states “No commission, ever.” It audits Seller Central CSV exports you upload, never connects to your account directly, and does not submit claims on your behalf (reimburseops.com, checked 2026-09-01). Flat fee versus commission is a real trade rather than a cheaper version of the same thing.

Frequently asked questions

Is Perpetua more expensive than Teikametrics? At the published entry point, yes, by a wide margin. Perpetua’s Essentials is $695/month for up to $10K in monthly ad spend; Teikametrics’ Essentials is $149/month billed annually or $179/month billed monthly for the same band (both pricing pages, data checked 2026-09-01). Above $10K both add a percentage, and only Teikametrics publishes the rate.

What percentage of ad spend does Perpetua charge? Perpetua does not publish one. Its pricing page shows Growth as “$695/mth + % of ad spend,” and its Terms of Service define Managed Ad Fees as “the percentage specified on the Order Form of the Media Costs on display and video advertising” (perpetua.io/tos, Last Updated May 26, 2026). The number exists only in your Order Form.

Does Perpetua offer a free trial? Not on its pricing page. On 2026-09-01 that page contained no mention of a trial and no self-serve sign-up. Teikametrics’ Essentials tier lists “Free Trial available.”

Is Perpetua the same thing as Sellics? Sellics was acquired on 19 April 2022 and merged into Perpetua, and sellics.com redirects to perpetua.io. Perpetua’s footer still links a page titled “Sellics joins forces with Perpetua.” The advertising half continued; product research, competitor tracking and review management did not — see our Sellics alternatives page .

Is Teikametrics’ Flywheel related to Flywheel Digital? No. Flywheel 2.0 is Teikametrics’ own former product name, now marketed as ARI. Flywheel Digital Limited is the entity that publishes Perpetua’s privacy policy, dated 06 August 2025. Same word, different companies.
