About us

We do not just preach online growth. We do it ourselves.

A small, experienced team from Noordwijkerhout, near Leiden. We run two businesses of our own and use exactly the same approach for our clients.

What Stijgt stands for

Not your average agency

We are not your average marketing agency. Alongside our clients we run our own businesses, Djunes.nl and Rijruimer.nl, and we do the marketing for them ourselves. If you are really good at marketing, you do not just do it for others, you do it for yourself too. Everything we learn there goes straight into the work for our clients.

  • 01

    Data first, then action

    We back every decision with numbers. We always start with a baseline, so growth is something you can prove, not just something you feel.

  • 02

    Accelerated with AI

    We use AI for research, content, ads and analysis. Faster and sharper, but a strategist always checks and decides.

  • 03

    Always one step ahead

    From GEO (being found in ChatGPT and Google AI) to new ad formats: we keep testing what works before the market catches on.

The team

Short lines, one fixed point of contact.

Specialists who really know your business, not a rotating cast of account managers.
