More than a new design.

A theme stops where your online store begins. We build the features that help your customers choose and buy, on top of your existing store. A few examples that are already live.

What you get

Your online store gets better every month. We do the work.

  • 01

    Ongoing development for a fixed monthly fee

    No separate quotes per change. If we see an opportunity or you have an idea, we build it.

  • 02

    CRO improvements, implemented right away

    We analyze your online store and roll out improvements in days instead of months.

  • 03

    Ready for peak moments

    Black Friday, the holidays, the season: we make sure promotions and changes are ready in time.

  • 04

    We find the bugs nobody sees

    For one client we found outdated review figures, a delivery time calculated with the wrong clock and a search function that missed the first letters.

  • 05

    Built for Google

    We measure every change against the Core Web Vitals, so your online store stays fast and stable.

  • 06

    Safe, and you see what changes

    We build and test everything in a preview first. It only goes live after your approval, and every version is saved. After each round you get before and after images with an explanation.

CRO agencies often charge thousands of euros a month.
We don't.

We improve your online store every month for a fixed fee, without separate quotes per change. That's possible because our specialists work with the Design by #SEM AI Agent.

What is the Design by #SEM AI Agent?

Our own tool for designing and building online stores. Our specialists use the agent to redesign your existing store and then keep improving it every month. You don't have to learn or operate anything: you only see the result.

Which online stores does it work for?

For stores on Lightspeed eCom and Shopify. We work in your existing store: no rebuild, no migration, and your back office stays exactly the way you know it.

What does it cost?

Normally €8,000 one-off for the setup and €750 per month. Until 30 November 2026 an introductory offer applies: €5,000 one-off and €500 per month.

How long am I committed?

The first 3 months are fixed. After that you can cancel monthly.

What happens to the changes if I cancel?

They simply stay live in your online store.

What does the monthly fee cover?

Continuous CRO improvements to your online store, without separate quotes per change. If we see an opportunity or you have an idea, we build it. We also prepare promotions for peak moments like Black Friday in time.

Will anything go live without me knowing?

No. We build and test everything in a preview first. It only goes live after your approval, and every version is saved, so we can always roll back.
