Meet 2021’s TEDxHHL speakers

Nine speakers will give you inspiring insights on the three different levels of the Butterfly Effect. Coming from different industry fields their background knowledge varies and provides you with a high diversity of viewpoints.

Manfred Hueckel


Former CCO of redbull

What is important to you? The answer to this question is probably one of the most important, yet most difficult ones to find out. Think of the answer as evolving over time like a caterpillar transforming into a butterfly – the answer won’t just pop up, it will develop. To assist specifically young people to find answers and, thus, the things that really matter to them, Manfred, former CCO of Red Bull and founder of St. Gilgen International School , developed the Butterfly-Model that he will share with us on May 7th.


sustainable governance expert

Do you know where all your clothes come from? Even if you think you know, you probably don’t. The least of us are aware of the complexity of global supply chains. This complexity brings along heavy burdens for the environment, but also for societies. However, alternatives are available. What these alternatives are and how more integrated governance frameworks could look like is going to be the topic of Lena, professor for environmental governance at Freiburg university and Freie Universität Berlin.

Lena Partzsch
Rolf Schroemgens


Founder of Trivago

Successfully turning a start-up into a billion euro business comes along with many invaluable lessons, certainly on leadership. But what makes a great leader beyond the theoretical scope of academic concepts? Having gathered long time experience as founder and CEO of Trivago, Rolf now wants to share his most important lessons and explain, why current narratives of leadership might not grasp what it leadership actually all about, creating systems of service.


Neuromarketing expert

Have you ever bought a product after watching a compelling ad? And have you ever felt bad afterwards? Most of us would probably answer both questions with a “yes”. The manipulative power of marketing has gained wide-reaching criticism throughout the past decades. Gesa, CEO of Kochstrasse marketing agency, will offer interesting concepts that might save the face of marketing in the future. 


Founder of mybacs

We are what we eat – more precisely – we are what we absorb. The gut microbiome is one of the most important and sophisticated systems in our body making vital contributions to our health. That’s why Carl-Philipp and a couple of friends founded Mybacs, a start-up distributing small pills targeting your gut health. In his talk, he will touch upon the importance of small bacteria on our overall health. 


PRofiling expert

Mark is a Crime Analyst (Profiler), trained and certified in the United States. He is a university lecturer for Behavioral & Cyber Psychology and takes you on a journey into the mind of the perpetrator. He has met and anonymously interviewed hackers, – including individuals whose crimes remain undiscovered to this day. Get a rare glimpse into the Psychology of Cybercrime from one of the best-known Profilers. In his interactive presentation, he focuses on the human factor and shows, how you can become a human firewall.


STEM ACTIVIST & SOcial entrepreneur

Does everything happen for a clear reason? This seemingly harmless question can, seen through the lens of science, quickly gain complexity. Caterin, physicist engineer and STEM activist, will propose an interesting answer in her talk. Doing so, she will introduce the butterfly effect and state some misconceptions about what the butterfly effect is regarded to be and what it actually is. 



Dr. Tobias Renk is one of the leading experts for organizational culture, digital transformation and innovation. He is a keynote speaker and author of various books. The latest one “Der Scrum-Reiseführer – Herausforderungen in der Praxis meistern” will get published later in this quarter. He has also been awarded one of the TOP 100 Excellent Trainers in 2021.  With TEDxHHL 2021, Tobias will share with you why innovation needs to happen in management.



We do not get to choose all of the circumstances of our lives. We cannot select the family we are born into, the country, the language we first learn how to speak, and as with so many other things we are powerless when it comes to unexpected changes in our circumstances. So, what do you do when life throws us a curveball? The only thing we have any power of is how we react to it, what we do with the lessons hidden behind what can be the most painful thing you have gone through so far. Stick to fear, or use it as a driving force, the choice is yours.
