Martijn Jonkman makes ambitious SME owners visible and recommended by AI models like ChatGPT and Perplexity through sharp analysis and hands-on strategy.
Jonkman Strategie exists for one reason: to make sure AI models know your business exists and recommend it when buyers ask. That sounds simple. It is not, and most people find that out too late.
I am an AI visibility specialist. I do the work myself. Every analysis, every strategy, every fix. You get my full attention, because I work one on one and that is a deliberate choice.
My background is in journalism and copywriting. That combination, deep research skills paired with the ability to translate complexity into clarity, is exactly what AI visibility requires. You cannot fool these systems with noise. You need to give them something real to work with.
Jonkman Strategie is built on the conviction that being present online is no longer enough. You need to be present where decisions are forming, inside AI models, and that is a very different game.
It started with a genuine obsession. When AI language models began gaining serious traction, I noticed something that nobody was talking about directly: businesses were invisible to these systems. Not because they were bad businesses. Because they had never been structured in a way that AI could understand and verify. I had spent years as a journalist and copywriter. My work was always built on the same two things: research and precision. Finding what is actually true, then communicating it clearly. When I looked at AI visibility as a problem, I recognized it immediately. This was a research and structuring problem, not a marketing problem. So I started testing. I put business names into ChatGPT, Perplexity, Gemini and Claude. I documented what came back, and more importantly, what did not come back. I mapped the gaps between what a business actually is and what AI models understand it to be. That research became the Agentability Framework, a structured method of measuring AI visibility across five dimensions, repairing the gaps, and measuring again after 90 days. I started with RAUWgesproken, a podcast whose team described my analysis as a mirror that did not lie. That validation confirmed the approach was right. Jonkman Strategie is still a solo practice. I am building toward a BV structure as the next step, but the core stays the same: one specialist, full attention, real results.

I use the Agentability Framework. It is a structured method, not a checklist, and it runs in three phases. First I measure. Ninety data points across five AI models, testing how your business is retrieved when buyers ask buying questions. Then I repair. Every gap between what you are and what AI understands you to be gets addressed directly. Finally, after 90 days, I measure again so you can see exactly what changed. The five dimensions are Identity, Relationships, Context, Authority and Actuality. Each one is a structural layer that AI systems use to assess whether a business is real, relevant and worth recommending. You do not get a report that sits in a folder. You get a strategy that is executed.
Establish what AI models currently understand your business to be. Name, category, ownership, location and positioning are checked across all five major models for consistency and accuracy.
Map which entities AI systems associate your business with. Suppliers, partners, clients and industry bodies all affect how AI models position you in a buying conversation.
Ensure AI models understand what you actually do, for whom and in which situations. Without clear context, systems default to generic descriptions that do not convert.
Identify and strengthen the signals that tell AI systems your business is credible and worth recommending. Credentials, publications and verifiable expertise all feed this layer.
Keep your AI presence current. Outdated signals weaken retrieval. This dimension repairs the gap between what your business is today and what AI models think it was six months ago.
A background in journalism built the research discipline that underpins every AI visibility analysis. Finding what is verifiably true, then structuring it precisely, is exactly what AI systems reward.
Years of professional copywriting created fluency in translating complex information into clear, structured content that both human readers and AI retrieval systems can parse and cite.
Exclusive focus on AI visibility as a primary speciality, not a side offer. This means the depth of knowledge here is not comparable to a general digital marketing agency that added AI to their service list.
The Agentability Framework is built and owned by Jonkman Strategie. It measures AI visibility across 90 data points in five AI models, repairs the identified gaps, and re-measures after 90 days.
Delivered an AI visibility analysis that the client described as a mirror that did not lie, confirming both the diagnostic accuracy and the practical value of the methodology.
Every recommendation is backed by measured data from actual AI model queries. Vague assurances about visibility do not help anyone. You get specific findings, specific gaps and a specific plan to close them. That is the only kind of work worth doing.
I do the work myself. There is no junior team handling your analysis while I manage the account. When you hire Jonkman Strategie, you get my full attention on your specific situation. That choice is intentional and it does not change as the business grows.
The goal is to move your business forward, not to make you feel good about where it is. If AI models are retrieving you incorrectly, that fact gets named clearly. A diagnosis that softens the truth wastes your time and delays the fix.
AI visibility is not won by producing more content or spending more on ads. It is won by being structurally present in the right way. The businesses that understand this early build an advantage that compounds over time.
Type your company name into ChatGPT right now. What comes back is exactly what potential buyers see when they ask an AI for a recommendation in your category. If the answer is thin, wrong or missing entirely, that is a concrete problem with a concrete solution. Reach out directly. I will tell you honestly what I see and whether I can help.
