The annual network event for
digital decision-makers

CIODAY is the annual network event for digital decision-makers in business, government, and everything in between. Not necessarily about the latest tech, this event brings together the community of CIOs, CDOs, and CTOs to share ideas, use cases, and best practices in an informal but luxurious setting. And, of course, we’ll announce the CIO of the Year 2024 and the winner of the Tech Hero Award.

Celebrate the 20th anniversary of the CIO community NL

In a world where technology is rapidly evolving to create breakthroughs, and where both challenges and threats have increased, yesterday’s lessons shape today’s innovations and tomorrow’s possibilities. Prepare for a journey through time and a glimpse into the future. Because in the tech sector: Tomorrow is today!

In 20 years we have witnessed impactful events and insights in various areas: technological, social, economic, (geo)political. nature & environment, public health and so on. As people, organizations and within the CIO community, we have learned that these developments always brought us threats and opportunities.
