Chantal Stekelenburg is Head of Hackers at Zerocopter. She takes care of one of the most important aspects of Zerocopter's services: the community of hackers. As a co-founder and organizer of WICCA (Women in Cybersecurity Community Association), she is also involved in bringing infosec ladies and security enthusiasts together to learn about exploits, hacking, incident response, forensics, the low-level stuff, hardware hacking, and especially making bad crypto jokes! Her main goal is to build a community of badass women in the Netherlands and hopefully inspire future generations to join keyboards and get the hacking started!

Jack of all trades. Master of some. Security engineer by day, cybercrime fiction writer by night. As a Security Engineer at GitLab, Valentine's work consists of putting out cyber fires, building automation to make her work easier, and designing value metrics for the division. Besides toying with digital systems, she’s a fiction writer who likes Star Wars, metal music, and useless things like chickens and D&D.
