Johannes is an ambitious, analytic, and at the same time a creative person who's able to reliably execute time-critical tasks and manage complex situations.
He is a valuable asset to any high power team.

Dr. Rouven Westphal (Managing Director @ Hasso Plattner Capital)

Johannes joined Thermondo even thought he could have picked from a variety of companies - but he chose a business that is aligned with his ideas and that he finds worthy to work for. This decision has always accompanied him during our shared time at Thermondo and made him not only work hard and deliver on his job, but also go beyond and invest in the social ecosystem of the tech team and the whole company. Thank you!

Kristofer Fichtner (Venture Partner @ PropTech1 & Co-Founder @ Thermondo)

Johannes brought an inspiring combination of deep passion for product development, remarkable technical genius, and genuine people leadership to voiio. He didn't just build; he innovated with a clarity that cut through complexity, always grounded by sharp business street smarts. More importantly, he led with a supportive spirit that empowered our team. His impact was unmeasurable.

Kerstin Michels (Co-Founder & Managing Director @ voiio)

Es ist immer gut, wenn man weiß, dass man sich auf bestimmte Leute verlassen kann.

Dr. Dirk Barchmann (CEO @ Institut für Verhaltenstherapie)

Johannes was an extremely valuable and pleasant team member. He is highly skilled and quickly familiarizes himself with new IT technologies.
He was very committed to the project, solved urgent and important issues without the need for supervision and willingly took on new responsibilities.
