Highlights

Collaboration

How does collaboration work?

Just 4 steps.
  • First meeting
    We start with an in-person or online meeting where we listen to your requirements, goals, and vision.


  • Solution proposal & workshop
    We’ll design the structure, content, and visual direction. Together, we’ll go through all the options, discuss the details, and prepare a clear implementation plan.


  • Development & implementation
    We create an interactive prototype. During development, we regularly share new versions for approval before production deployment.


  • All set! What’s next?
    We provide hosting, regular security updates and patches, as well as ongoing monitoring. We’ll also guide you through managing your content and understanding your site’s architecture.

We care

About every unit. That's why it's important to us
that every website we deploy
aims for the highest values
for Google and AI

Independent Website Performance Verification

Verifiable Performance & Environmental Footprint

Click to test our website — or any other.

Google PageSpeed

What is it?

Google PageSpeed is a free tool from Google that evaluates the technical quality of a website — loading speed, mobile performance, accessibility, best practices, and SEO.

Simply enter a URL and the tool will show you a 0–100 score along with specific actions you can improve.

Why does it matter?

  • Slow pages drive visitors away — most leave if a site loads for more than a few seconds.
  • Speed is a ranking factor Google uses in search results.
  • Better technical performance = better UX and higher conversions.

Website Carbon

What is it?

Website Carbon is a tool that estimates a website’s carbon footprint — in other words, how much energy is consumed when a page is loaded.

The consumption depends mainly on data size, number of requests, and code efficiency.

Why does it matter?

  • “Heavier” websites (large images, inefficient code) consume more energy and load more slowly.
  • Efficient websites are faster, cheaper to operate, and more environmentally friendly.
  • A low data footprint is a sign of a modern, well-designed website.
