Selected work

Three examples, measured.

Three client projects, by name. The figures come from a Lighthouse run under mobile conditions, as of August 3, 2026. Every reference, with its starting point and stack, sits on the work page.

Services

Three routes, depending on where you start.

What you need depends on what you begin with: nothing at all, an existing site, or an idea that is more than a website.
  • New build

    A new website from the ground up: structure, copy, design and build from one team. Imprint, privacy policy and measurement are in from day one.
    from CHF 2'500
  • Rebuild

    Your content stays, the site is rebuilt technically and visually. Pages and rankings move across with you, with a redirect for every old address.
    from CHF 1'200
  • Web app

    Applications with a database, sign-in and logic of their own. Client portals, booking tools, internal reporting systems.
    CHF 12'000–⁠35'000+
All figures are indicative and exclude VAT. After the first conversation you receive a written quote with a fixed price. Until then no work happens that costs anything.

Process

From the first question to going live.

Five steps, identical for a new build and a rebuild. The duration depends on scope, the order does not.
  1. Briefing

    1 conversation
    A conversation about your business, your clients and what the website has to achieve. Free of charge. Afterwards both sides know whether it is a fit.
  2. Concept and structure

    2–4 days
    Site architecture, content plan and value proposition. You see in writing what goes on which page before a single colour is chosen.
  3. Design

    2–5 days
    The home page and one subpage are designed in full. Only once the direction is right is the rest built on top of it.
  4. Build

    1–2 weeks
    Built in Next.js and TypeScript, with a preview URL from day one. You see every interim state instead of being surprised at the end.
  5. Launch and handover

    1 day
    Measurement, corrections, going live. You receive the repository and every access credential. From that day the code is yours.

Studio

Two founders. No layers in between.

Whoever designs it also builds it. Across the whole project you speak to the same two people. 77 websites and 17 web apps between us. No project manager in between, no hand-off to a team you never meet.
