The team

Gunther van Adrichem

Gunther van Adrichem

CEO

To call Gunther a geek is an understatement. As a young guy he loved to work at with all the machines at his dad’s greenhouse, take them apart and put them together afterwards.

After graduating from the University of Applied Sciences he worked in the construction industry. He moved to Schiphol to start at the real estate department. After his first project for the security department, they insisted that he should stay. It opened the opportunity to combine his talents for constructing, project management and technology. His crown jewel project was the co-development and introduction of the Provision body scanner, which was deployed on a global scale.

Michiel Poppink

Michiel Poppink

CCO

Michiel started his career at Randstad Staffing Service. Michiel was fascinated how to differentiate his service from the competition which started his passion for innovation, sales and marketing. In 1999, he started a company and took a patented process to the market. In 2005, he worked for a governmental platform to stimulate innovation for Small Medium Enterprises (SME’s) with a focus on building bridges between big organisations/ multinationals and innovative companies. He was the co-founder of the European First Responder Innovation Managers (EFRIM) platform, improving the innovation capacities of first responders in Europe.

At Stage Gate 11 Michiel loves to work on the commercial and marketing side of the company.

Thomas Hof

Thomas Hof

Security Engineer

Thomas started working on the Delta R technology during his Internship at Point FWD, at the time it was little more than a conveyor with a prototype of the system built out of aluminium profiles. Working closely with Dr. Dubroca, who was a Post Doc in the research group of the technology, taught him a lot about the technology and through the expertise of Gunther he has learned a lot of the skills necessary in a development team. Today, he uses these skills combined with his knowledge of the aviation security market to add value in the development of the Delta R Shoe Scanner and other projects where his experience in research & development and spectroscopy are of added value.

Thomas has a strong drive to learn, is passionate about sports and practices a martial art.

Jim van Etten

Jim van Etten

Research Engineer & Project Coordinator

With a background in the field of biomedical research and experiences with various innovative analytical x-ray spectroscopy techniques, the step to the research and development of safety and security systems is not a traditional one. The science geek inside him has allowed his interests in anything scientifically challenging and the lust for more knowledge, to expand his horizon to beyond the laboratory alone. While his strength lies mostly on the research in the laboratory, it will give Jim a great deal of satisfaction when research is turned into a real-life application.

Tackling interesting scientific questions but also maintaining the quality of the processes to a high standard, has become his motivation to keep improving.

Mariska Huis

Mariska Huis

Product Manager

Due to her background in Aviation Security technology domain, she likes to absorb knowledge on new security techniques and managing passenger flows. She has experience on small and major airports, both within and outside Europe. Blending into a different work- and business culture with language barriers is not problem for her as Mariska is able to adjust her pace at any time.

Mariska is passionate about travelling to learn about different cultures and try new cuisines. Not only keeping a list of places visited but also airports seen.

Jim de Waal

Jim de Waal

Sales Engineer

Is broadly educated in Aviation Security and Technology: from the operations side to graduating in the field of cyber security in relation to the GDPR law and legislation. With a passion for interacting with other people and with other businesses, he always thinks in solutions and looks where he can apply the same solution for different problems.

Besides this, he sees life from the bright side and is opportunistic. Have we mentioned yet that he was the first in our office to throw 180 in darts?

If you want to talk about your security needs or just would like to have a coffee at the Schiphol based office of Stage Gate 11, just give him a call!
