Web / Studio practice · B2B web design

A website that converts, not one that decorates.

UX, design, development, CRO. We build fast and clear B2B websites, made to turn your visibility into qualified meetings, and to carry your image.

The challenge

Your website, your first salesperson.

Your website works around the clock, even when your teams are asleep. It is often a prospect’s first contact with you, and sometimes the only one before they decide.

Yet most B2B websites are little more than handsome brochures: slow, confusing, with no clear path to the action. The visitor leaves, and the marketing budget leaves with them.

A good website is not simply better looking, it is more effective. Speed, clarity, proof, a guided journey: every detail serves conversion as much as image.

Our approach

From the journey to the conversion.

Four steps that build on each other, from the structure through to continuous optimisation of the conversion rate.

  1. 01

    Framing and UX

    Objectives, audiences, journeys. We build the architecture and every page around a single goal: turning a visitor into a contact.

  2. 02

    Design and content

    Art direction, mockups, messaging. A design that carries your brand and leads the eye, effortlessly, all the way to the action.

  3. 03

    Development

    Fast, clean, accessible build. Performance, technical SEO and mobile display belong to the foundation, never to the options list.

  4. 04

    Optimisation (CRO)

    Launch, measure, iterate. We test, we adjust, we improve the one thing that really counts: the conversion rate.

What we do

The web studio, in full.

Complementary areas of expertise, brought in according to your objectives. We define the right scope at the diagnostic stage, never a fixed package.

  • UX and architecture

    Journeys, site structure, wireframes. The structure that walks a visitor through to booking a meeting.

  • UI design

    Art direction, mockups, component system. An image that matches the scale of your ambition.

  • Development

    Fast and robust websites (Astro, headless and the like), custom integrations, clean code you can keep alive over time.

  • Redesign and migration

    We modernise what already exists without sacrificing your SEO, your content or your history.

  • CRO and A/B testing

    Conversion rate optimisation: we frame a hypothesis, we test it, we settle it on the numbers.

  • Performance and technical SEO

    Core Web Vitals, accessibility, structured data. A site that is fast and well indexed from the design stage onwards.

Frequently asked questions

What company leaders ask us.

It depends on the scope. A focused brochure site does not call for the same work as a full redesign, with a new structure and new content. We set the schedule at the diagnostic stage, based on your objectives and your deadline.

Both. We always start with an audit. If your site has foundations and SEO worth keeping, we rebuild while preserving what you have earned. Otherwise we start again on a sound base. What we are after is performance, not change for the sake of change.

We favour performance-oriented stacks (Astro, static sites or headless when it makes sense), without over-engineering. The technical choice follows your real need, speed, editorial autonomy, room to grow, rather than the fashion of the moment.

Technical SEO is there from the design stage: speed, structure, markup, structured data, accessibility. That is the foundation. Editorial SEO (content, keywords) comes next, and it is groundwork we can drive alongside the paid acquisition practice.

You do. We deliver a site you own and we train your teams to run it. And if you would rather hand us the controls over time, we can take care of maintenance and continuous optimisation (CRO).

There is no fixed price. The cost depends on the technology chosen and on the scope of the project: a focused brochure site does not call for the same work as a full platform with a new structure and new content. A redesign, which has to work around what exists and preserve the SEO already earned, generally comes out higher than a build started from a sound base. We scope it at the diagnostic stage, once the real need is on the table.

Yes. The speed of a site weighs directly on its conversion rate: the longer a page takes to appear, the more visitors leave before they have even seen it. The data published by Google on web.dev establishes this link between performance and conversion. That is why we treat performance as a foundation, not an option, from the design stage onwards.

A website that performs deserves traffic.

A website that converts gives its full effect when a strong brand and controlled acquisition feed it. Explore the other practices.
