What moves when we take over an account

Real work first, with figures that come from reports and can be audited. Then sector reference scenarios, so you can see the lever each type of business responds to.

Real work

What we have built and what we run

Two products of our own, live on the stores. And Amazon accounts we run every month with figures you can audit.

Challenge

Good product, poor execution: listings with no A+ content, inherited campaigns with no structure, one product in free fall and no reliable data to decide where to spend.

What we did

We restructured campaigns by objective rather than by product, built the full A+ content for the falling product using deliberately conservative language to avoid compliance issues, recovered the Buy Box on the affected listings, and set up monthly reporting that separates ACOS, TACOS and organic sales.

Result

August closed as the best month since we took over the account. And it grew the healthy way: traffic and conversion rose together, with organic sales growing faster than ad spend. The falling product recovered 68% in a single month after the A+ content went live.

We built the whole app: a conversational companion that remembers what you talked about yesterday and asks about it today, the Bible rewritten in present-day Spanish with a mode that highlights exactly what changed against the 1909 Reina-Valera, prayers generated from the person's actual situation, and reading plans. With in-app subscription and free trial.

NDA

And the accounts we cannot show you

We run more Amazon accounts than the ones listed here. Most of our agreements include confidentiality, so we do not publish those clients' names or figures without written permission.

Take it as a reference point: it is the same discretion you will get when we work together.

Sector scenarios. The figures are typical orders of magnitude for the sector, not a specific client's.

Method

Five steps, and each one hands you something

This isn't a diagram to fill a slide. Every step ends in a deliverable you can decide with, and if a step adds nothing, we skip it.

  1. We analyse

    Account, catalogue and numbers. We look at margin per SKU with fulfilment, returns and ad spend included, not just top-line revenue.

    DeliverableA report of your margin leaks ranked by money, not by urgency.

  2. We design the system

    We decide what to sell, on which channel and at what price. And what to stop selling, which is usually the decision that frees the most margin.

    DeliverableA 90-day plan with an owner, a metric and a cut-off threshold per lever.

  3. We build

    Listings, campaigns, integrations and whatever software is missing. It ships in phases, with the previous one already being measured.

    DeliverableA live channel and a tracking dashboard with your own data in it.

  4. We optimise

    Two-week cycles. Measure, cut what doesn't pay and double down on what does. No waiting for month-end to react.

    DeliverableA fortnightly review with decisions made and their impact in euros.

  5. We scale

    A new marketplace, a new country or a new product line. Only once the unit economics can carry the next step.

    DeliverableAn expansion model with investment, break-even point and timeline.
Why us

The difference isn't the price, it's the model

We're comparing ways of working, not companies. If your current agency sits in the right-hand column, keep them.
Traditional agency

An account manager relays your questions to the team that actually does the work.

Velycio

You talk to the specialist working on your account. Nothing gets lost in translation.

Traditional agency

You get split into tasks: one person on ads, another on content, nobody on the business.

Velycio

One lead owning the whole project, with the P&L in front of them.

Traditional agency

A monthly report of vanity metrics: impressions, clicks, reach.

Velycio

A dashboard with margin, TACOS and stock turn, plus this week's decision.

Traditional agency

Offices, structure and overhead you end up paying for inside the fee.

Velycio

Fully remote. The budget goes on specialist hours and software.

Traditional agency

They take your project on even when the team is already buried.

Velycio

Assignment by real capacity: if there's no room, we tell you before you sign.
