Perpetua alternative
RedHen Labs vs Perpetua
$695 a month before the undisclosed percentage starts. Here's how they compare for Amazon PPC management.
Perpetua review, from a competitor: what it does well, and where we differ
Perpetua is an enterprise-grade Amazon advertising platform used by large brands and agencies, with algorithmic bidding and deep campaign automation. It is a capable tool for that buyer. Its published pricing starts with Essentials at $695/month for up to $10,000 in managed ad spend; above that, their pricing page lists a Growth tier at "$695/mth + % of ad spend" — and the percentage itself is not stated anywhere on the page.
RedHen Labs is a focused Amazon advertising management platform with built-in profitability tracking. At a flat $19 to $129 a month — never a percentage of ad spend — it gives mid-tier sellers the automation and visibility that used to require enterprise tools or agencies.

The number they publish, and the one they don't
Perpetua does publish a starting price, which is more than several competitors manage: $695 a month covers up to $10,000 of managed ad spend. Cross that threshold and the plan becomes "$695/mth + % of ad spend." The percentage is not disclosed on the pricing page. So the honest summary is that you can find out what Perpetua costs at low spend and cannot find out what it costs at the spend where most of its customers actually sit. RedHen Labs is $129 a month at $10,000 of ad spend, at $100,000, and at every number in between.
They are built for a bigger buyer
Worth saying plainly: Perpetua's top tier begins above $500,000 a month in ad spend, which tells you who the product is really for. If you are running that kind of budget across DSP and multiple retailers, an enterprise platform with a dedicated team is a reasonable thing to buy, and we do not compete for that. We are built for the seller running their own Sponsored Products, Sponsored Brands and Sponsored Display — where a $695 floor plus a percentage is simply the wrong shape of bill.
What you’d pay at your ad spend
| Monthly ad spend | Perpetua (Essentials, then Growth) | RedHen (Professional) | With RedHen, a month | With RedHen, a year |
|---|---|---|---|---|
| $5,000 | $695 (Essentials) | $129 | $566 less | $6,792 less |
| $10,000 | $695 (Essentials) | $129 | $566 less | $6,792 less |
| $25,000 | Not published (Growth, from $695) | $129 | At least $566 less | At least $6,792 less |
| $50,000 | Not published (Growth, from $695) | $129 | At least $566 less | At least $6,792 less |
What each includes. Perpetua: Essentials, for up to $10,000 a month in ad spend, has AI-powered bid optimization, automated keyword harvesting and performance and profitability reporting. Growth, over $10,000, adds hourly reporting and intraday optimization. RedHen Labs Professional: everything in Growth, plus the rule engine — bid rules, keyword harvesting and negative keyword automation, budget and placement automations, dayparting — and the plain-English AI assistant.
How it’s calculated. Essentials is $695 a month for "Up to 10k in monthly ad spend". Over $10,000, Growth is "$695 /mth + % of ad spend", and the percentage isn't on Perpetua's pricing page, so those rows can't give a figure: they start at $695. Premium, over $500,000 a month, is custom. Ad spend means the spend the tool manages. Source: perpetua.io, checked October 31, 2026. RedHen’s figure is the Professional plan’s monthly price, the same at any ad spend ($110.08 a month billed yearly). AI assistant: $20 of usage included each month, and it stops at $50 unless you raise the limit.

How RedHen is different
Perpetua lets you choose whether keyword harvesting is "fully automated, after a set number of conversions, or to be manually approved," while its AI handles bid optimization. RedHen Labs gives bids the same choice: they wait for your approval unless you switch them on.
- Rules first, AI as the advisor. Rules settle the clear-cut calls, and the AI suggests changes inside hard limits. Auto-apply is off by default; switched on, the AI can only nudge bids.
- It waits when the data is thin. RedHen won’t cut a bid on too little data. It looks again next cycle instead of guessing.
- The same flat fee at any spend. $19, $69 or $129 a month, whatever you spend on ads.
- You approve, and one click undoes it. Changes wait for your approval unless you choose otherwise, and each one is logged with a one-click undo.
Why we don’t charge more
We could charge more. We don’t, and it isn’t because this is a lighter product — it’s because it’s a focused one. We built the things an Amazon seller actually touches every week and left out the twenty modules that pad a suite. A focused product costs less to build and less to run, so it can cost less to buy.
The other reason is simpler. By the time a seller has paid referral fees, fulfillment, storage, returns, and advertising, a lot of hands have already been in the till — and then an agency wants a percentage of sales and a tool wants a percentage of spend. The person who designed the product, paid for the inventory, and carries every bit of the risk ends up with the thinnest slice of it. We decided not to be one more toll on that road. $129 is a number we can hold at any account size, which means growing your business never costs you more to keep using ours.
Questions sellers ask about Perpetua
How much does Perpetua cost?
Perpetua's published pricing starts with Essentials at $695 a month for up to $10,000 in managed ad spend. Above that, their pricing page lists a Growth tier at "$695/mth + % of ad spend." (As published on perpetua.io, checked October 31, 2026.)
Does Perpetua charge a percentage of ad spend?
Yes, once you cross $10,000 a month in managed ad spend, and the percentage itself is not stated anywhere on their pricing page. So you can find out what Perpetua costs at low spend, but not what it costs at the spend where most of its customers sit.
What would RedHen Labs cost instead?
RedHen Labs Professional is $129 a month at $10,000 of ad spend, at $100,000, and at every number in between, against Perpetua's $695 for up to $10,000. It is never a percentage of ad spend. Growth, for PPC management with AI bid changes you approve, is $69 a month.
What happens on day one after I connect?
RedHen Labs reads your account: campaigns, keywords, search terms and spend. It doesn't move a bid on its own. The changes it proposes wait in a queue for you, and every one you approve goes into a log you can undo with one click. Sponsored Display changes always wait for you, on every plan.
Should campaign automation make changes without me?
Perpetua's bid optimization is AI-powered, and its keyword harvesting can be fully automated, wait for a set number of conversions, or be manually approved. We think a human belongs in that loop. Untethered, AI is bad at Amazon PPC: it optimizes the number it's told to, not the business behind it. In RedHen Labs, AI is one tool among many and works inside guardrails. By default it proposes, you approve, and nothing changes until you do.
When is Perpetua the better pick?
If you run a very large budget across DSP and multiple retailers and want an enterprise platform with a dedicated team. Perpetua's top tier begins above $500,000 a month in ad spend, which shows who it is built for. RedHen Labs is built for sellers running their own Sponsored Products, Sponsored Brands and Sponsored Display.
