Hands-on Amazon Growth Partner

Focus on what moves the business.
Then execute until the numbers move.

For established Amazon brands. I find the few levers that matter most — then work them myself, inside Seller Central and Amazon Ads.

This quarterTwo levers.
Everything else waits.

How I work

Most brands don’t need more activity.
They need better priorities — and someone to execute them.

Diagnose

Ads, catalog, pricing and P&L — read as one system.

Focus

Pick the few levers that move profit. Park the rest.

Execute

Hands-on, inside the accounts.

Measure

Against the baseline. Scale, fix or stop.

I read the business as one connected system, identify the few levers that matter most — and execute them together.

ResultWithin approximately five months, average monthly revenue grew from ~£60K to ~£170K, while average monthly profit increased from ~£15K to ~£32K.

The case

SituationAn apparel-accessories brand in Clothing, Shoes & Jewelry already had demand, but ad spend wasn’t following the economics. The best-converting SKU received only around 50% of total spend — capping both paid scale and the organic rank momentum that comes with it.

FocusBudget allocation · Scaling the winners · Price & deal mechanics · Organic rank

ActionsRestructured spend toward the highest-converting campaigns and products, pulling budget out of lower-value traffic. Once the structure was clean, scaled the top performers aggressively. Then launched a deal and moved price from $18.99 to $14.99 to drive volume — capturing the lower referral fee during the deal window — and ran paid and organic growth as one system.

ResultWeekly net profit and units rose sharply after the takeover. The product reached #2 in its Best Sellers subcategory, and its main-category rank moved from roughly #30,000+ in early February to #3,946 — a materially stronger position against the category leader.

monthly net profit

~$190K → ~$370K average monthly profit

On roughly flat unit volume and essentially the same ad spend

View case & evidence

The case

SituationA large Home & Kitchen seller — roughly $40M a year across a broad catalog. Scale wasn’t the problem; profitability was. The catalog structure had drifted and a meaningful share of ad spend wasn’t earning its keep.

FocusCatalog structure · Ad waste · Deal strategy · Rank-focused PPC

ActionsMarch — catalog. Restructured the catalog: merged variations where it made sense and separated listings that needed to be reconnected correctly, improving catalog logic, product attractiveness and AOV. April–May — profitability. Cut unnecessary ad spend hard and tightened the advertising structure. May–August — profitable scale. With margin flexibility restored, introduced a more aggressive deals strategy and focused PPC on the keywords most likely to lift organic rank.

ResultAverage monthly net profit roughly doubled, from ~$190K (Nov–Feb) to ~$370K (May–Aug), while monthly units stayed roughly flat and average ad spend was essentially unchanged at ~$320K a month. Organic position improved too: on one core product, the 90-day average Best Sellers rank (#1,686) is ahead of its 12-month average (#1,956).

FAQ

Questions brands ask first.

Who do you work with?

Established Amazon brands, typically six to eight figures, that already sell and want growth that shows up in profit, not only in revenue.

Are you an agency?

No. You work with me directly. I set the priorities with you and do the work myself, inside your accounts.

What does “hands-on” mean in practice?

I work inside Seller Central and Amazon Ads myself: campaign structure, search terms, bids and budgets, placements, pricing, promotions, catalog and listings.

Can you work alongside an existing agency or internal team?

Yes. I can work alongside an internal team or an existing agency, as long as ownership and decision-making are clear. My role is to identify the priorities, align the work and stay hands-on where I can create the most impact.
