About Let It Grow

An independent Belgian agency built by entrepreneurs and e-commerce operators, for brands that want to build something durable on Amazon.

Our story

An agency created by entrepreneurs. We created Let It Grow after noticing a simple reality: today, Amazon represents a tremendous growth lever, but its complexity prevents many companies from fully exploiting its potential.

After developing our own business on Amazon, we decided to go further by bringing together three entrepreneur brothers and two specialists who spent several years supporting international brands within a major European Amazon agency.

Our ambition is simple: to allow companies to focus on their products while we handle the complexity of Amazon. We are proudly independent, not owned by, sponsored by or affiliated with Amazon which lets us stay 100% aligned with your interests.

How we work, in practice

We do not publish named client results or unverifiable figures (see our Amazon Compliance page). Here are anonymized, representative examples of the kind of work we do (general illustrations of our method, not specific client claims).

Multi-marketplace brand, baby & childcare category

Situation: Fast-growing catalog, but incomplete product listings and advertising spread thin across several accounts.
Action: Rebuilt product content (titles, A+ Content, Brand Store), consolidated the campaign structure, and set up shared weekly reporting with the client's in-house team.
Outcome: A clearer, easier-to-read account for the client's team, with advertising steered from product margin instead of a generic ACOS target.

Cosmetics brand expanding into new European marketplaces

Situation: Presence limited to a single marketplace, with a small in-house team.
Action: Feasibility review, marketplace prioritization, listing localization and a launch coordinated with VAT and EPR compliance.
Outcome: Gradual expansion into several additional European marketplaces, built on a catalog and advertising foundation reusable from one market to the next.

Small appliances brand, Vendor Central

Situation: Loosely structured Vendor Central relationship, with recurring chargeback disputes.
Action: Set up structured order and chargeback tracking, with direct coordination with the relevant Amazon teams.
Outcome: Faster dispute handling and a more predictable Vendor Central relationship for the client.

We are an independent service provider and are not affiliated with or endorsed by Amazon.
