A small account in 2023, £850,000 a month by January 2026
Ancient + Brave is a premium collagen and wellness brand selling in the UK, the US and Europe, and it compounded with us for three years. At the start of 2023 the Amazon account was small. By December 2025 it was turning over close to £800,000 a month, having grown 101% into 2024 and 160% into 2025 while the category averaged 36%. That is a growth rate 344% above the category, and it did not come from one good year. The second year was the bigger one. The engagement ended in January 2026, on £850,000 — the account's best month in three years.
Buying growth is straightforward if you are willing to lose money doing it. The constraint on this account for three years was that both numbers had to move in the same direction at once. They did: total advertising cost of sale held at 14.6% while revenue more than doubled, and advertising return finished 44% above the 2025 category average of 1.7. We have written separately about why that pairing is the whole test, because a growth figure with no efficiency figure beside it is half a story.
The results page carries the same figures as a summary. This page carries the order the work happened in, which lever moved which number, and what was in the way at each stage. The order matters more than the list, because every item on it is affordable on its own and most accounts do them in the wrong sequence.
The listing
The listing
First, the listing treated as advertising
Advertising into a page that does not convert buys traffic and very little else, so the page came first. Main images were rebuilt to work like ads rather than pack shots, A+ Premium went onto the main lines, and the brand store was rebuilt to sell rather than to look like a website. Alongside that we ran regular customer polling, so the content answered the questions buyers actually ask instead of the ones a brand team assumes they ask.
In a supplement account the thumbnail has to carry format, dose and benefit at roughly the size of a postage stamp, which is a harder brief than most categories set. That argument is made in full in its own post, and what happens after the click, which is a different job measured by a different number, is set out here.
- Main images built like ads, not packaging
- Brand store rebuilt to sell, not to look like a website
- A+ Premium on the main lines
- Regular customer polling, so content answers real questions
Ranking
Ranking
Then ranking, before the spending
Organic position is what makes advertising affordable later, so the ranking programme came before the budget went up. Priority products were moved into the top five, new launches were managed rather than listed and left, and the subscription base was built underneath the whole account until subscriptions were running at 25 to 30% of monthly revenue.
That subscription number is the one a wellness brand should read first. Supplements are a repeat-purchase category, so subscription share compounds in a way it never does for a one-off purchase. It is the difference between an account that has to buy every sale and one that opens each month with a base already in it. How the same discipline plays out across the category is on our page for Amazon growth for supplement and wellness brands.
The US and Europe were launched from that position rather than into it. The sequencing we use is to get the home marketplace ranking and profitable first and expand from strength, with catalogue, content and advertising built for each marketplace instead of listings flipped live and left to find their own level.
- Ranking programme moved priority products into the top 5
- New product launch management
- Launched the US and Europe
- Subscriptions grown to 25-30% of monthly revenue
The full funnel
The full funnel
Then advertising across the whole funnel
With the pages converting and the priority products ranking, the advertising could be built as an architecture rather than a set of campaigns. Video Sponsored Brand ads, hourly dayparting so budget goes to the hours that convert, and a deliberate split between defending branded search and buying non-branded growth.
That split is where the efficiency number is won or lost, and it is the single most tempting place to flatter an account. Branded search is the cheapest traffic in any account and most of it was arriving anyway, so spending more of the budget there lowers the headline cost of sale without selling anything extra. How to size the split, and how to test it with a holdout rather than an opinion, is the mechanic behind holding 14.6% while the topline doubled.

DSP
DSP
DSP last, and it is where the step change happened
Programmatic came last because it earns its place only when there is enough demand to retarget and enough margin to fund prospecting, and both of those are made by the three stages above it. On this account it is where the step change happened: RippleTarget custom audiences bringing in new customers at a positive return, retargeting to bring existing customers back, Fire Tablet and Prime TV placements, and imagery built for programmatic rather than cropped from the listing.
We do not publish a DSP-specific figure for this account and we are not going to estimate one here. Retargeting and prospecting are two different jobs and a blended return hides which one was done, which is the argument in our post on when Amazon DSP is worth it and when it is not. What the published record supports is the sequence and the direction, not a number attached to this stage alone.
- RippleTarget custom audiences: new customers at a positive ROAS
- Retargeting to bring customers back
- Fire Tablet and Prime TV ads
- Custom imagery built for programmatic
What was actually hard
None of the four stages is difficult on its own. The difficulty is that each one is most tempting at exactly the point where it is least useful. DSP looks best when growth is flat, which is usually a ranking problem. Branded defence looks best when the cost of sale is under review, which is usually when it is doing the least good. Three years of an account is mostly a series of decisions about what not to do yet, and the reason this one compounded is that the order held even in the quarters when it would have been easier to buy the number.
The other hard part is that an efficiency figure does not simply hold while a topline doubles. It gets pulled about constantly, because every new launch, every new marketplace and every new campaign type starts inefficient by definition, since it is buying data before it is buying sales. The parts of the account that are already working have to carry that, which is a question about sequencing and budget discipline rather than about advertising skill. That is what the five disciplines run as one system is for, and it is the argument against running strategy, catalogue, PPC and DSP as four suppliers who meet by email.
What this case study cannot tell you
There is no control account. We cannot tell you what Ancient + Brave would have done on Amazon over the same three years without us, because nobody runs the same brand twice. The nearest thing to a control is the category rate of 36%, and it is not one: it is an average across brands with different products, prices, launch calendars and budgets. Read the 344% as the difference between this account and its category, which is what it is, rather than as the difference we made, which is not a number anyone can honestly publish.
The figures here are ours, taken from the account we ran. That is the same position every agency case study is written from, including the ones that do not say so, and it is worth applying to this page the same test we set out in our post on what to check before you believe an agency: can you see the number you are billed on inside your own Seller Central. On our accounts you can, which is why we are comfortable naming the client, the figures and the years together on one page.
What this would look like on your account
This is one account in one category, run founder-led over three years. The pattern that transfers is the order, not the numbers: make the page convert, earn the ranking, build the advertising architecture, and only then buy audiences. If you want the cross-client view, including a brand taken from zero to profitable in under six months, it is on the results page.
What an engagement costs is published before you speak to anyone. A monthly retainer sized by your catalogue plus a commission charged in marginal slices, so the effective rate falls as sales grow, and you can model it for your own revenue in ten seconds. Every engagement starts with a free Amazon account audit: your listings, campaigns and catalogue, with a prioritised set of first moves, so you see how we think before you pay for anything.
