About

With more than 25 years of experience as CEO and Chief Product & Technology Officer, I set the company's strategic agenda and direct product development efforts, successfully guiding cross-functional teams to deliver on key projects and enhance business growth. My management style is best characterized as servant leadership: I empower others to achieve the best result together. I thrive best in organizations that require change. From start-up to scale-up, scale-up to dominant or for changes in enterprise organizations. Ambitious, driven, innovative, loyal and service-oriented are words that describe me well. As a manager, I do not only take into account the interests of the (internal) customer, but also those of my colleagues and stakeholders. My passion for IT enables me to quickly adapt to new systems and (digital) environments. CEO / CTO / CPTO / CxO (fractional / interim)

      We were the first cow monitoring system with an ear sensor for cows. We have a lot of dairy farming experience, did years of research, testing, developing, and we update our system’s hardware and software bi-weekly. Our technology gives you extremely accurate information about your herd’s fertility, health, and nutritional status. The ear sensor fits around an official animal identification RFID tag and stays put thanks to an effective attachment mechanism. In just a single action, you can place the sensor in a cow’s ear. It’s easy to remove and attach to another cow, too. And there’s no need for recharging batteries and adjusting collars. Easy does it!
