Derk Gähler

Co-founder & Digital Expert

Jesse looks after the commercial line and the personal contact; Derk connects positioning, technology and online marketing. We get to know your organisation and keep the whole picture in view, so we do not just build what you ask for but understand why it has to work for you. And after launch we simply stay on.

Work

Built to be seen

Below is a selection of the websites we have designed and built. This is not a portfolio to admire: the work itself shows what you can expect from us better than any promise could.

Where it usually goes wrong

Not more to manage. Better connected.

The website lives at agency A, the newsletter in tool B, leads arrive in a shared inbox and quotes sit in a folder. Familiar, and nobody’s fault. The moment those parts know about each other, your week gets noticeably calmer.

Today: separate islands

  • Websitestandalone, unmeasured
  • Newsletteranother tool, another list
  • Leadsin a shared inbox
  • Quotesin a folder on the server
  • Reportingmanual, after the fact
  • Follow-upwhen someone remembers

Tomorrow: one system

  • Lead arrivesstraight into the CRM
  • Follow-upautomatic, on time
  • Websitemonitored 24/7
  • Marketingtied to revenue
  • Reportingreal-time, one view
  • Historycomplete and searchable

How we work

You know exactly where you stand, up front.

Four phases, fixed deliverables and one point of contact. No surprises halfway, no waiting for an answer.

  1. Growth Scan

    Week 0 · free

    We look at your website, visibility and follow-up. You get a concrete picture of what's slipping through, even if you never hire us.

    • Scan report
    • Priority list
    • Budget indication
  2. Strategy & structure

    Week 1–2

    Positioning, audience, message and site structure. We decide which pages exist, what they must do and how we measure success.

    • Positioning document
    • Sitemap & wireframes
    • Measurement plan
  3. Design & build

    Week 2–4

    Design, copy and build run in parallel. AI speeds up research and production; strategy and final editing stay human work.

    • Design
    • Copy
    • Working site in preview
  4. Launch & growth

    Week 4–5 and beyond

    Live, measured and monitored. Then we roll out the agreed marketing and CRM automations and keep improving.

Frequently asked

Ask us anything, we rather enjoy it.

Still turning something over? Please ask. You get a substantive answer from Jesse or Derk themselves, as soon as possible after it reaches us.

No. We use AI for research, first concepts and repetitive work, and that saves you weeks of lead time. The design, the strategy, the brand choices, the development and the final check are done by hand. Your site is built around your positioning, not around a template, and a person always looks at it before anything goes live.

Partner solution

Circular IT through our partner

For organisations that also want to organise their IT hardware more cleverly and circularly alongside their digital growth system, we work with a specialist partner: Circular IT Group. They provide the hardware, the expertise and the execution; we make the introduction and stay your point of contact for the digital side.

How the partnership works
  • Buy, rent or take as a service, through the partner
  • Take-back and certified data wiping
  • Reporting for your sustainability statement

Next step
