UNTOLD is a conference about ideas that leave us speechless.

Some ideas tell the same tale, others tell a different story. A few might just help us tell things apart. But truth be told, only time will tell which ones do. This year's event will tell you a thing or two about UNTOLD ideas that need to be shared.

2 half-day chapters of peeking through the keyhole to discover the hidden gems from the UNTOLD worlds of Science, Technology, Ethics, Design and Human Connection; from powerful secrets to utterly unimaginable scientific discoveries.

Our speakers

TEDxVienna 2021 will bring together a group of 18 expert thinkers and doers across a wide range of fields to help share UNTOLD ideas. We’re joined by prominent global academics, educators, researchers, philanthropists, environmentalists, scientists, technologists, artists, activists and more for a full day of immersive discussions.

In line with this year's theme, the exact schedule will remain UNTOLD and will be revealed at the event.
