David van Driessche
David van Driessche is a physicist by education who has spent his career working at the intersection of technology, production workflows, and people. After starting out in software development, he has held roles ranging from CTO and COO to CEO, with a consistent focus on automation, standards, and real-world production challenges in the graphic arts and document technology space.
David is known for combining deep technical understanding with the ability to explain complex topics clearly and pragmatically. His background spans PostScript, PDF, workflow automation, output devices, and industry standards, but his particular strength lies in identifying where systems, processes, or assumptions break down—and figuring out how to fix them.
Today, David is Chief Evangelist at callas software, where he works with end users, partners, integrators, and OEMs to improve PDF technology and help organizations get the most out of it. Whether the challenge is technical, organizational, or human, David enjoys finding the penguin in the room—and moving it somewhere more productive.
