What PROMEXX does
PROMEXX Technical Automation B.V. is a Netherlands-based technical software development firm founded in 2004, headquartered in Best with a second office opened in Rotterdam in March 2026. The company specializes in embedded and real-time software for complex machines and mechatronic systems, with engineering competencies concentrated in C++, C#, and Python across motion control, machine vision, robotics, and Smart Industry/IoT applications. All employees are software engineers with a stated passion for mechatronics and robotics; the firm deliberately does not employ dedicated testers, scrum masters, or data scientists, and engineers test their code directly on physical machines rather than purely in simulation.
The firm serves a blue-chip enterprise customer base in the Dutch Brainport (Eindhoven) and Rotterdam high-tech corridor, with publicly named clients including ASML, Philips, Lely, Thermo Fisher Scientific, Vanderlande, Besi, ASMPT ALSI, and Keiron Technologies. Revenue is generated through two professional-services models: long-duration detachment (contract staffing) arrangements where engineers are embedded in client teams for an average of 2-3 years, and fixed-price project engagements for the machine- and apparatus-building industry. Pricing is not publicly disclosed, but compensation structures for engineers include salary plus a profit-sharing bonus equal to half of the margin generated on their work, with references to 13th through 16th month payments.
In September 2023 the management team — John van Meel, Kris Hoogendoorn, and Oscar Reynhout — together with Vondel Private Equity completed a management buyout from founders Eric Schuerman and Maarten Beijloos. Since then the company has invested in a new headquarters office ('The Curve' in Best, effective January 2025, formally opened September 2025) and expanded to Rotterdam, and appointed Jasper van Zuijlen as Business Manager in February 2026. Headcount sits in the 51-100 range, and go-to-market is exclusively direct enterprise engagement with no self-service, marketplace, or reseller channels.
