Our CEO
Pierre Vriens is an industry veteran with over 40 years of invaluable experience. His journey began after earning a degree in Mathematics and Computer Sciences from KU Leuven, a renowned Belgian university, back in the eighties. In 1990, he ventured into the world of ChangeMan ZMF 3.2.1b, laying the foundation for his remarkable expertise. Fast forward to 2000, and Pierre assumed the role of CEO as one of the founding members of AbitMore bv, further enriching his extensive experience to this day. The glowing testimonials he has accumulated throughout his extensive career leave no doubt that he is a preeminent authority in the realm of ChangeMan ZMF.
A significant portion of his perspectives, aspirations, and business ethics regarding ChangeMan ZMF stem from his interactions with Doug Troxel, also known as DDT, whom he has met multiple times over the past three decades. From Doug, he has received numerous recommendations on selling, supporting, and developing AbitMore’s add-on products for ChangeMan ZMF. Particularly noteworthy is a moment around 1990 when DDT asserted that supporting products like CSP, VAG, or IDMS/ADSO in ChangeMan ZMF was impossible. However, about a year later, Pierre demonstrated to DDT how he achieved it, earning the acronym CSP as "Come & See Pierre." Subsequently, DDT (SERENA) even flew Pierre around the world to implement CSP support in ChangeMan ZMF for a new customer.
