My approach

Designed for behaviour.
Built by me.

Instead of design thinking, I use the Behavioural Design Method by Astrid Groenewegen (SUE). I start with what you want people to do and find out what stops them. Then I design and build the ads, landing pages or website myself, so you don't need a developer. AI speeds up research and production, so you get the work sooner.

01 · Method

Four steps from brief to result

Source: The Art of Designing Behaviour, Astrid Groenewegen

I follow the Behavioural Design Method by Astrid Groenewegen of SUE. It replaces design thinking in my process. Every step ends with something you can review.

  1. Insight

    I map what people do now, what you want them to do, and what stands in the way.

    You get What drives and blocks your audience
  2. Intervention

    I turn the strongest force into ad angles and page changes, based on psychology.

    You get Concepts to choose from
  3. Impact

    I build the ads or pages and test them with real people, in A/B tests or ad sets.

    You get Live tests and results
  4. Implement

    What works goes live wherever it fits, with a check that it stays fair to your audience.

    You get The winning version, live

02 · Why behavioural design

Behavioural design vs design thinking

Design thinking asks what people need, then designs something new for it. Behavioural design asks why people who already want something still don't act, and removes what stops them.

With ads and websites, that's usually the job: people know the product, but don't click, sign up or buy.

The difference

Design thinking Behavioural design
Starts with What people need What people should do
Based on Interviews and empathy Psychology and behavioural science
Delivers A new product or idea Changes that get people to act
Use it when It's unclear what to build People know the offer but don't act

What moves people to act

The four forces in SUE's Influence Framework

Push people to act

  • Pains Frustrations with how things go now
  • Gains What gets better once they act

Hold people back

  • Comforts Habits that feel easy and familiar
  • Anxieties Doubts and fears about the new step

Most ads only add reasons to act. I also remove what holds people back.

03 · Design and build

From design to live, without a developer

I design and build the ads, landing pages and websites myself. There's no hand-off to a developer, so what goes live is what was designed.

For you that means one contact person, fewer steps between an idea and a live test, and quick changes once a test is in.

Usual setup: 4 people (strategist, designer, developer and CRO analyst) with 3 hand-offs. With me: 1 person does research, design, build and test, with 0 hand-offs.

04 · AI

Where I use AI

AI speeds up the slow parts of the work, so you get it sooner. What to make, what goes live and what counts as a win is still my call.

AI tools Claude Code to build sites and tools, Higgsfield for visuals

AI helps, I decide

AI helps with I decide
Research Summarising reviews, surveys and competitor ads Which insight to build on
Ideas More hooks and headlines, faster What fits the brand and the audience
Production Resizing formats and writing code What it looks like and what goes live
Testing Sorting and reading results What won, and what to test next

Rules I work by

  • Start from what people should do, not from the deliverable.

  • Remove what holds people back before adding more reasons to act.

  • Test it before calling it a win.
