Building human–AI ecosystems

My name is Raoul Grouls (1977), welcome to pttrn. I design AI strategies that execute, and help humans and AI cooperate in meaningful ecosystems. My neuro-symbolic approach makes AI useful where hallucinations cannot be tolerated, such as governance. As an enthusiastic lecturer and speaker, I explain difficult topics to any audience.

Since 2012, I've been designing and building AI systems, guiding the complete process from "we want something with AI but we don't know exactly what" through development to a product in daily use. Before that I worked in mental health care, first as a caregiver and later as an innovation manager. Those years taught me that people, not systems, decide whether change works.

Today, I focus on three things:

• Intelligent human-AI ecosystems — designing systems in which humans and AI collaborate accountably, as partners rather than tool and user.
• Strategy that ships — connecting AI strategy to execution: understand what an organisation really needs, model it, and help teams excel with AI.
• Neuro-symbolic research — making AI useful where hallucinations cannot be tolerated: reliable logic integrated with language models, grounded in Category Theory and Geometric Deep Learning.

Meaning first. I want to understand how people solve the problems in their organisation, what it really cares about and what drives it. Then I model the system with mathematics that is expressive enough to capture the creativity of the process. I excel at explaining difficult topics, which creates what an ecosystem of people and AI needs: a shared language.

pttrn is pattern without its vowels. Finding patterns is just the start; humans bring it to life with the vowels.
