The Person Behind Event Vault

Hi, I'm Johan Kleijn

I'm the founder and developer of Event Vault, based in Delft, The Netherlands. With a background in building engineering and a deep passion for automation and problem-solving, I have spent the last few years building software that makes complex processes simple and accessible. Event Vault is the result of that same drive — professional event technology that is barrier-free and stress-free for organizers of any size.
