Openbedrijvendag

Every first Sunday in October, hundreds of companies—big and small, from a wide variety of sectors—open their doors to the general public across Flanders, Brussels and Wallonia. In 2025, this must-attend event celebrates its 35th edition on Sunday October 5th.

Visitors get a unique opportunity to discover how their favorite products are made, see how companies operate day-to-day and even find out where their neighbors work. This special occasion brings the public closer to the business world with a personal and tangible approach.

For companies, it’s an exceptional opportunity to showcase their expertise, unveil new buildings, products and colleagues, and strengthen their brand image and employer branding authentically.

The event emphasizes innovation, transparency and local engagement, meeting both the curiosity of visitors and the communication goals of participating companies.

In addition to the physical open day, Voka now offers a virtual experience: companies are accessible 24/7 via digital tours, allowing everyone to participate, even from a distance.

With over 500,000 visitors expected, it’s one of the country’s largest open events, supported by a broad media campaign including the newspaper De Zondag, which publishes a guide listing participating companies.
