About

Mary- Jo de Leeuw is founder and President of the Platform Internet of Toys. In addition she is an associate partner at Revnext, a consultancy firm in technology driven strategies and as acts as Vice President of the international Women in Cyber Security Foundation.

Mary-Jo de Leeuw has been fascinated by bits and bytes ever since she got a Commodore 64 back in the ‘80’s. From a very young age she has been manipulating and hacking digital systems, games and toys. As she tried to build and alter her very own Mario1 game and Donkey Kong, she got nicknamed “Mario” instead of “Mary-Jo”.

In 2015 Mary-Jo de Leeuw reprogrammed a connected toy doll to speak like a terrorist and switched on microphones and camera’s in popular toys from a distance. Partly because of Mary-Jo’s efforts, dangerous toys are starting to be banned from toy stores today. The efforts for the Platform Internet of Toys gained Mary-Jo, or Mario, yet another nickname: “Rebel with a Cause”. Today this rebel is a well known and very much appreciated thought leader in the infosec world. She publishes regularly on her findings, speaks at international conferences and is the go-to media expert on everything concerning her old passion “bits and bytes”.
