Maarten Mortier is a venture capital investor at Entourage who brings 20+ years of hands-on building experience, including roles as Head of AI & Innovation at Henchman, and positions himself as a deeply technical SaaS product and infrastructure expert rather than a purely financial investor. He thinks at the operating system level about AI integration, has written extensively about how operating systems underuse LLMs and the need for better OS-level primitives like agentic sandboxes, and has become a visible voice in Belgian tech policy debates by bringing his scale-up experience to discussions about how nations should build technology.
