Why We Exist
About Us
The shift from search to synthesis is happening now. When people ask AI for recommendations, the model doesn't return a list of links—it makes choices. It synthesises, summarises, and selects. If your brand isn't part of that synthesis, you're invisible.
Most marketing agencies haven't noticed. They're still optimising for algorithms that rank pages, not models that understand meaning. We built PromptMarketing because someone needs to bridge that gap—with rigor, not hype.

Felix Koole
LLM Visibility Engineer
Felix Koole
LLM Visibility Engineer
Felix works at the intersection of SEO and AI systems, which turns out to be exactly where the interesting problems are right now. He spent five years building websites and running SEO as a freelancer before AI search started reshaping the field. That background gives him something most AI researchers don't have: a grounded sense of how visibility actually works in practice, and why the shift to generative answers changes everything for brands. He holds a BSc in Artificial Intelligence from Utrecht University and is currently completing a Research Master in AI. He's deep into how LLMs and embeddings work at an architectural level — how they encode meaning, what they pay attention to, and why certain content gets retrieved and cited while other content doesn't. That architectural understanding lets him build hypotheses from first principles and design experiments that actually test the right things. At PromptMarketing he helps brands get cited and surfaced by AI systems — translating that technical depth into concrete strategy, backed by controlled experiments and real data.
