FAQ

Everything you need to know before we start.

Is DataMarketLab a marketplace agency?+

Yes. DataMarketLab is a marketplace agency and consultancy founded by Tidiane Hubert and based in Bordeaux, France. It works with e-commerce brands and sellers on Amazon, Mirakl, Cdiscount, ManoMano, Carrefour and 25+ marketplaces across France and Europe.

What services does DataMarketLab offer?+

Marketplace audits, strategy, seller account management, catalogue and product feed optimisation, pricing, Retail Media and launching on new marketplaces. For a one-off issue at a fixed price, there is also Ticket Marketplace.

Can I pay through my company to reclaim VAT?+

Yes, absolutely. I provide an invoice, which lets your company reclaim the VAT on it.

Is the audit free?+

Yes, 100% free. It's a chance to review your catalog, pricing, and active marketplaces, with zero commitment on your end.

How long is the session?+

About 25 minutes, over video call. Plenty to identify what's blocking your growth and walk away with a first action plan.

I'm just starting out on marketplaces, is this for me?+

Yes. The session is exactly meant to clarify where to start, whatever your current level.

Which marketplaces can you help me with?+

All of them — Amazon, Cdiscount, ManoMano, Carrefour and many others, in France and internationally.

What happens after the audit?+

You walk away with a clear action plan. If you want to keep working together, we figure out next steps then — nothing is imposed.

What does a marketplace consultant actually do?+

A marketplace consultant runs your presence on marketplaces — Amazon, Cdiscount, ManoMano, Carrefour and others — covering catalog, pricing, logistics and sales activation, with profitability as the goal, not just visibility.

Why hire a consultant instead of managing marketplaces in-house?+

Every marketplace has its own rules, feeds and pitfalls. A consultant who already knows them saves you from costly mistakes and skips the learning-curve time.

How does DataMarketLab work?+

DataMarketLab combines both: the method and continuity of a marketplace agency, with a single point of contact, Tidiane, who knows your account inside out.

Can you help me expand internationally?+

Yes. I speak English and also work with sellers looking to grow on marketplaces outside of France.

How much does an engagement cost?+

It depends on your needs — a one-off audit, monthly support, or full management. We talk pricing directly during the free session.

Do you work with big brands or small sellers?+

Both. I've worked with brands like Eden Park and Compagnie de Californie, as well as sellers who are just getting started on marketplaces.
