The People Behind the Stage

All volunteers. All passion.

About TED 

TED is a nonprofit organization devoted to Ideas Worth Spreading. Started as a four-day conference in California 30 years ago, TED has grown to support its mission with multiple initiatives. The two annual TED Conferences invite the world’s leading thinkers and doers to speak for 18 minutes or less. Many of these talks are then made available, free, at TED speakers have included Bill Gates, Jane Goodall, Elizabeth Gilbert, Sir Richard Branson, Nandan Nilekani, Philippe Starck, Ngozi Okonjo-Iweala, Sal Khan and Daniel Kahneman.

The annual TED Conference takes place each spring in Vancouver, British Columbia. TED’s media initiatives include, where new TED Talks are posted daily; the Open Translation Project, which provides subtitles and interactive transcripts as well as translations from volunteers worldwide; the educational initiative TED-Ed. TED has established the annual TED Prize, where exceptional individuals with a wish to change the world get help translating their wishes into action; TEDx, which supports individuals or groups in hosting local, self- organized TED-style events around the world, and the TED Fellows program, helping world-changing innovators from around the globe to amplify the impact of their remarkable projects and activities.

TEDxZurich is a day of wonder, inspiration and awe. We hope you mix and mingle with our knowledge thirsty audience and uncover exhilarating topics together that are sure to fascinate

The event is a series of short talks, ranging from approximately five to eighteen minutes length. In between speakers you will have the opportunity to enjoy performances, eat some eclectic food choices and wonder around our creatively inspired event spaces.

About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TED Talks video and live speakers combine to spark deep discussion and connection. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations.)

Core Team

Florian Bucher


Originally planning to get a business degree after high school, Florian has spent his last two and a half years seeking out challenging enriching experiences, working a daycare center, as a sailing instructor, managing a small ice cream business, bartending, organizing parties and finally leading a Sales team for a Startup. Currently, he works as a Product Operations Specialist for Coople, while trying to biohack himself to live on 4 hours of sleep, so he can start his studies the way he has long promised his parents.

Christina Haupt

Christina Haupt


Christina’s TEDx career started with organizing TEDxWooster at the College of Wooster, where she earned her BA in Studio Art and Philosophy. Returning to Switzerland, she continued her studies with a Masters of Art in, Public Spheres and Art Teaching, from the University of Luzern. But, just doing one thing has never been Christina’s style. In her free time, she practices the art of conjuring time out of thin air to satisfy the scheduling conflicts of her many diverse interests and hobbies. If she isn’t out running, climbing a wall, painting, writing poetry and blog entries, attending concerts, or reading books on philosophy, she’s probably connecting students, friends, and family with big ideas. That’s what first drew Christina to the TEDx community and has her excited about organizing TEDxZurich.

Erik Slabber TEDx Zurich

Erik Slabber

Speakers Lead

Erik was born and raised in South Africa, meaning that he regularly endures questions like “Do you speak African?”, “I have a friend from Africa, do you know him?” and “Did you ride to school on a zebra?”. He came to Zurich for his Bachelor studies and enjoyed it here so much that he stayed on for his Masters and even decided to torture himself by starting a PhD in regenerative biology. When he is not working in the lab, he reads scientific papers for fun, plans experiments and works on figures for upcoming publications... OK, so now that Erik’s boss is satisfied and has stopped reading this bio, he actually enjoys gaming, cinema, boot restoration, supporting the Springboks and pub quizzing.

Sara Leidinger tedx zurich

Sara Leidinger

Audience Experience Lead

A volunteer at heart and passionate Yoga practitioner. With a deep interest in personal development and being fascinated by the power of the mind, Sara believes that sharing ideas worth spreading can make the world a more connected place. The momentum of our 2017 event with the theme “opening doors” was a kickstart and eye-opener for Sara who then just flipped her career path to 180° – from a corporate global sales environment to a year full of volunteering and studies of holistic healing arts. This kind of momentum is what drives her in creating experiences that last.

Estella di Silvestro​

Finance Lead

Curious about the world and the people around her, Estella tries to find the right balance between what she studied – Accounting & Finance – and what really excites and warms her heart. She likes to do a lot of things and she likes to do them well. That competitive spirit comes from more than ten years of swimming as a competitive athlete. Her flair for fine food finds its roots in her culture and upbringing, her love for the mountains and for backpacking started -and never stopped growing, since coming to Switzerland. She strongly believes that all these passions, along with reading all types of books, travelling and dedicating herself to building long term friendships are what complement crunching numbers to ensure an open mind and a richness in generating ideas. Worth sharing.
