The problem we solve

Growing in online channels has become absurdly complex.

⚙️

Integration chaos

Disconnected ERPs, desynchronised stock across channels, real-time errors that cost you sales and reputation.

🔥

Your internal team is firefighting

80% of the time goes to resolving operational incidents. Only 20% is left for strategy and growth.

🗺️

Marketplaces without structure

Being on Amazon or Miravia without active optimisation burns margins. Presence without management is money wasted.

🌍

Internationalisation is paralysing

Cross-border has a thousand variables: taxation, logistics, language, local platforms. Without an expert partner, it doesn't scale.

Why ST21

We're not a marketing agency. We're your operational arm.

Media agencies manage budgets. Technology consultancies build tools. ST21 does both — and also runs the business while you focus on the brand.

Digital channels open

ST21 didn't just build our integration with Amazon and Miravia — they manage the entire catalogue every day. It's like having an internal eCommerce team of 20 people.

Head of Operations Spanish fashion brand — Expansion into 2 countries
+110% marketplace sales · 6 months

We'd been stuck with the same platform for years and couldn't connect it to our logistics. ST21 solved the integration in 8 weeks.

Frequently asked questions

What our clients
ask most

Depending on the agreement, we can establish non-compete clauses by product category and market. We assess this case by case in the first consultation. On channels like Miravia, our position as an Official Partner allows us to negotiate exclusive conditions for each brand.
Technical integration projects are typically operational in 6–10 weeks. The first marketplace sales results appear within the first quarter. For cross-border, the realistic horizon is 3–6 months depending on the target market.
We work with a mixed model: a monthly operational management fee plus a variable component tied to results. That way our incentives are always aligned with the growth of your business. The details are agreed during the initial call.
No. We work both with brands starting from scratch and with companies that already have infrastructure and need to optimise it or connect it to new channels. The first consultation is precisely for diagnosing the starting point.
Primarily Western Europe (FR, DE, IT, UK), the Nordic markets and China (Tmall, JD.com). We have native team members in Spanish, English, French, German and Mandarin Chinese. Every market has its own platforms, regulations and consumer behaviours: our advantage is that we know them all.
