Services

An e-commerce agency that builds stores that actually sell.

We design, build, and scale online stores, from Shopify and headless storefronts to fully custom commerce. Since 2022, working as part of larger agency teams, our engineers have built e-commerce for leading European fashion and retail brands, and we bring that same standard to businesses in Croatia and the DACH region.

  • ›Shopify, headless & custom commerce builds
  • ›Replatforming & store migrations
  • ›Performance & Core Web Vitals optimization
  • ›Applied AI: search, recommendations & support
  • ›SEO & AI-search (RAO/GEO) optimization
  • ›Ongoing support and iteration

E-commerce development, end to end

Storefront design, replatforming, custom features, checkout and payments. Whether you are launching a new webshop or rebuilding one that has outgrown its platform, we handle the engineering so the store stays fast, stable, and easy to run.

Speed that pays for itself

We migrate storefronts to modern technology and cut page-load times, because speed is not a vanity metric, it is conversion. We build on modern, headless-capable stacks and hold every page to its Core Web Vitals.

Applied AI, where it actually helps

AI is a tool, not a headline. We add it to your store only where it moves real numbers:

  • ›Smart product search and recommendations that lift average order value
  • ›Support agents that answer from your own catalog and policies
  • ›Automated product descriptions and content at scale
  • ›Demand and inventory signals for smarter merchandising

Found by Google and by AI

A fast store nobody finds is wasted. We build in technical SEO, structured data, and Core Web Vitals, and optimize for AI answer engines (RAO/GEO) so your brand shows up when customers ask ChatGPT, Perplexity, or Google AI, not just classic search.

Frequently asked questions

How much does it cost to build an online store?+

It depends on scope. A focused Shopify launch is very different from a custom headless build. We scope every project to a clear, fixed outcome and tell you the honest range before you commit, so there are no surprises.

Do you work with Shopify, or custom platforms?+

Both. We build on Shopify and other proven platforms when they fit, and go headless or fully custom when a business needs more control. We recommend the option that serves your store, not the one that bills the most hours.

Can you rebuild or migrate our existing webshop?+

Yes. Replatforming and migrations are core work for us: moving a store to a faster, more maintainable stack without losing rankings, data, or sales during the switch.

Do you do SEO and AI-search optimization too?+

Yes. Every store we build ships with technical SEO and structured data, and we optimize for AI answer engines (sometimes called RAO or GEO) so your products surface in ChatGPT, Perplexity, and Google's AI results, not only classic search.

Can you add AI to our store?+

Yes, where it earns its place: product search and recommendations, support agents grounded in your catalog, and content automation. We add AI to move real numbers like conversion and average order value, not for the buzzword.
