Karel Maesen is a seasoned geospatial software entrepreneur with 19 years of professional experience, currently leading Geovise from Antwerp. With an MSc in Computer Science from KU Leuven and a decade-long tenure as Head of Unit Geo-ICT at K.U.Leuven’s SADL, he blends academic rigor with practical product development in geo-ICT. He combines hands-on back-end engineering—evidenced by contributions that extended Hibernate ORM to support Oracle SDOGeometry—with strategic ownership of geospatial solutions. Karel’s work sits at the intersection of databases, spatial standards and enterprise integration, making him comfortable turning complex spatial requirements into production-ready systems. Colleagues describe him as a pragmatic problem-solver who moves fluidly between code, architecture and client-facing responsibilities.
