Every year since 1991, on the first Sunday in October, hundreds of Flemish companies from a wide range of sectors open their doors to the general public during Voka Open Company Day. This is the moment when visitors get a unique glimpse behind the scenes of entrepreneurial Flanders – from innovative SMEs to large manufacturing companies. With hundreds of thousands of visitors, Voka Open Company Day is always a huge success. In 2026, this national celebration of entrepreneurship will take place for the 36th time, on Sunday 4 October 2026. Make a note of this date in your diary and discover up close how Flemish companies work, produce and innovate.
