RedHen Labs vs Perpetua
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 pricing page lists Essentials at $695 a month for up to $10,000 in managed ad spend, and above that a Growth tier described as "$695/mth + % of ad spend" — with the percentage itself not stated anywhere on the page. RedHen Labs is $129 a month flat at every level of ad spend.
The number they publish, and the one they don't
Perpetua does publish a starting price, which is more than several competitors manage. But cross $10,000 of monthly ad spend and the plan becomes "$695/mth + % of ad spend", and the rate is not disclosed. So 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 sit. RedHen Labs is $129 at $10,000 of ad spend, at $100,000, and at every number in between.
They are built for a bigger buyer
Their top tier begins above $500,000 a month in ad spend, which tells you who the product is really for. If you run that kind of budget across DSP and multiple retailers, an enterprise platform with a dedicated team is a reasonable purchase and we do not compete for it. We are built for the seller running their own Sponsored Products, Sponsored Brands and Sponsored Display, where a $695 floor plus a percentage is the wrong shape of bill.

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.
