Meet Our Ambassadors

Advocates who actively connect companies to us and provide our customers access to their international networks

Jacqueline Beer


A goal is a dream with a deadline. When your goal is clear, it is important to share that goal to meet that deadline. You need to connect people to it. The more employees feel connected to their work, the greater the success of the organization. Jacqueline knows from her experience as a supervisory director, chairman, adviser and director exactly how she can create this enthusiasm and involvement with employees and management.

She knows how to identify and analyze the core qualities of an organization. But she also knows in particular how you can let employees excel in these core qualities. She herself seems business-like, but she knows how to motivate and stimulate in a truly human way. Her aim is to share those skills and thus share success.

Pjotr van Schothorst


Pjotr is a private investor in clean energy startups. After studying physics at TU Delft, he worked at Shell for 12 years, always introducing new technology into Shell’s mainstream business. In 2000, he left Shell to start some new technology companies himself: Act-3D, the company behind Lumion, a software product for architecture visualization; and VSTEP, a company developing training simulators in several international markets.

Both companies made several product & market pivots during their 20 year lifetime, and Pjotr experienced the effects these can have on the company’s success first hand. Both companies have grown considerably since their start, and Pjotr now uses the dividends of one of them to invest in new ventures that support the energy transition. Over the last 2 years, he took part in 6 seed rounds and 2 Series A rounds, and he still learns every day from all these companies, lessons he is keen to share with other startups and scaleups.
