Get ready!

The world we live in today is rapidly changing, with or without us. Adapting to these changes is essential for our life and this means switching our stance. This may take a little effort but will enable us to look at things differently. We want to shift our persective and spark curiosity and excitement!

Let us blow you away at TEDxTUBerlin 2021 with live speakers who will inspire us with new ideas and views on different topics such as technology, entertainment and design. Together we will experience the TEDx spirit of ideas worth spreading!


The wait is finally over!

At the end of 2019, we announced our main event SWITCHING STANCES for June 2020. Then, a global pandemic hit us all and turned the world upside down. We had to postpone our event without knowing when it will finally take place. Now, we have an answer to that question. We are happy to announce that SWITCHING STANCES will now take place in Spindler & Klatt on the 26th of September 2021!

We want every participant to have fun and to feel safe during our event. Meeting the common regulations on protection against infection is therefor important to us. Therefor, we only allow fully vaccinated and recovered (not longer than 6 months) participants to our event. If the course of the pandemic won’t allow us to hold the event in presence at Spindler & Klatt, we will perform it online via live stream.


Event language will be ENGLISH.

Spindler & Klatt

The Spindler & Klatt is a multifunctional catering concept Restaurant, club and event location that meets the highest functional and aesthetic demands. The focus is on reducing to the essentials. Original Asian antiques were combined with a puristic, clear furniture concept.The flexibly positionable furniture elements, the extensive sound and lighting technology, as well as the projection surfaces let Spindler & Klatt shine in a suitable atmosphere for every type of event. The implementation of Spindler & Klatt is based on the idea of a studio, a microcosm in the metropolis of Berlin directly on the Spree and directly on the former east-west border.
Typically Berlin – confident, convertible, creative and international.

Back then it all started with four types of savory popcorn, today our product range also includes sweet popcorn, chips, flips and cornballs.

We are constantly developing ourselves and our snacks in order to offer you healthy, exciting and sustainably produced snacks that are fun and at the same time meet your and our requirements for ecological and social sustainability. Our snacks are vegetarian and whenever possible vegan, gluten and lactose free. You can rely on that at Wildcorn.

manna Naturkosmetik

Manna’s story began in 2004, when our son got a rash all over his body a few days after he was born. In favour of our child, we banned all cosmetic products from the house that contain chemicals and thus the natural cosmetic products of Manna were evolved. Those are chemical-free, naturalness and contain health, a lot of work and knowledge. Manna’s products are not only gentle on your skin, you can also be sure that not a single animal has suffered because of them.

We are building the filling station network of the future.
On a purely rational level, our job is this: we, H2 MOBILITY Deutschland GmbH & Co KG, are responsible for establishing a nationwide hydrogen infrastructure in Germany. In fact, however, we are building a mobile future of rapid refueling, long ranges, clean and quiet mobility. This is truly one-of-a-kind: there is no comparable entrepreneurial initiative anywhere in the world that sees the introduction of a zero-emissions fuel as a national duty and works towards it in this spirit.
