Custom websites & apps

We build websites found by Google and AI.

We build custom websites your customers can find on Google and in answers from ChatGPT, Gemini or Perplexity.

What we do

Our solutions

We build websites and web applications that are fast and ready for AI search, from company websites and web applications to websites for real estate developments. Every website we make can be found by people, Google and AI assistants.

Presentation websites

Presentation websites

Responsive websites that load fast and display well on any device. Clear navigation leads visitors to an inquiry or an order.

Websites for real estate developments

A new-build website where buyers pick an apartment straight from the building visualization, view its floor plan and see at once what is still available. The sales team manages availability and prices on its own.

AI discoverability (GEO)

AI discoverability (GEO)

We optimize websites for ChatGPT, Claude, Gemini and Perplexity: structured data, llms.txt and content that AI can cite, so that it knows about you and recommends you.

AI search

Google is no longer enough

Fewer and fewer people turn to Google; more and more ask AI instead. When someone asks ChatGPT for “the best company in your field”, your website has to be part of the answer. That's exactly what we build every website for.

People ask AI

Millions of users search for products and services every day through ChatGPT, Gemini, Copilot or Perplexity instead of classic search.

AI only recommends what it understands

AI assistants cite websites with clean structure, clear content and structured data. An ordinary website is often invisible to them.

We build it in from the ground up

Every website we build has the technical foundation for AI search built in: from schema.org data and llms.txt to content written so that AI can cite it.

About us

From websites to web apps

  2. Today we focus mainly on user interfaces for demanding web applications.

  3. We build every project on current technologies and prepare it from the ground up for customers who arrive from Google and from AI.
