Gunther van Adrichem


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 science 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

Sales & Marketing

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 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 platform, improving the innovation capacities of first responders in Europe.

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