Mario Sgarrella
Switzerland, Director
Mario is the founder of unpluggo.ch, digital liberator, trainer and keynote speaker. For over a decade, he worked in marketing, PR, advertising and lobbying. He regularly used social media to gather vast amounts of data on the “engagement” of target audiences in order to re-target them with intrusive messages. And in his free time, he was addicted to social media. Then his son Luca was born. It was a wake-up call: the “net” discovers that you’ve become a father and bombards you with all kinds of baby products, ads and suggestions. Too much was too much. He cancelled all his social media accounts and took control of my smartphone notifications, emails and instant messages. And he started unpluggo: Switzerland’s first digital wellness centre.

Linde Kouwenhoven & Nini Fritz
Australia, Co-Directors
Hello from Australia! We are Linde & Nini, the co-founders of the Digital Detox game eyeConnect - stronger than wifi. As self-renowned Digital Detox experts (...at least Nini wrote her master thesis about it), we are on a mission to make the world a more meaningfully connected place.
Because we believe that real connection is what happens in between two wifi signals and therefore we invented a conversation-sparking card game that is created to make real people more exciting than social media. From Australia into the world we want to raise awareness that the best things in life happen when we look up from our phones.

Mihai Dumbravă
Romania, Director
I’m a learning instigator with 20+ years of experience in skill development and performance training. Technology has always been my partner a powerful tool that helped me grow impact and deliver results.But I’ve also seen how thin the line is between productive use and constant distraction, between empowerment and digital overload. Now, as AI becomes part of everyday life, I believe conscious tech education is no longer optional. We don’t need less technology we need better awareness, clearer boundaries, and smarter habits.
Through Smarteris.org, I promote digital consciousness for individuals, teams, and organizations that want performance without losing clarity.
