Entrepreneur at heart

About Jan-Paul Kreukniet.

I am Jan-Paul Doesn't Wrinkle. From an early age, I've wanted to help people and make an impact. That started with my own entertainment agency in the Benelux, followed by a marketing agency.

Years later, when I joined the National Police through a hackathon as an Innovation Consultant a.i., I discovered how you can really make a difference with (secret) technology and innovation. Those experiences sparked my passion for justice and my desire to help people in difficult situations.

After five years of police, I briefly switched to the business community — including Coolblue and Blackbear — to broaden my view. But I soon noticed that I missed what I valued so much about the police: personal contact and the real impact of my work. That's why I obtained my Private Investigator degree and decided to start my own detective agency: Haagsch Recherchebureau, focused on personal attention, high-quality investigation, operating safely and continuing to innovate.

To really help you in the best possible way, I have specialized in OVR-OT, SRO, OT-A, OT-B, VIB, OSR-1 and Drone Operator A1/A3 + A2, among others. This way, together with my team, I can always choose the right approach and we will continue to innovate, so that we are not only of today, but also ready for the issues of (over) tomorrow.
