Frequently asked questions
Yes. Most of it happens online, and we're happy to visit for kickoff and delivery. We also work with a number of clients in Belgium.
Not really, but below €1,000 a project with us usually isn't the best use of your budget. We'll tell you so.
For existing clients, yes, through improvement hours in the maintenance plan. For new collaborations we prefer to start with a defined project.
Within one working day you get a substantive answer from Jesse or Derk themselves.
Jesse or Derk is your point of contact and guards the line of your project. The work itself we do with a team of specialists we bring in per question: design, development, content, advertising. So you have one counterpart, and there is more behind it than a single diary.
We dig into what is going wrong now and where you want to get to. That usually produces a short list of what would pay off most, even when that means you need something other than a new website.
No, and neither does the Growth Scan. You keep the report and the priority list either way, even if you decide not to work with us.
Who we are
You work with fixed points of contact, backed by a team of specialists.

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.
