Zeile7 - The jack of all trades
I do all the things here!
Egoditor - Interim Chief Technology Officer
I helped navigating an organically grown and successful company through a phase of massive growth.
Element - Co-Founder CTO
As a co-founder I helped build and grow ELEMENT from the very beginning. Together with the small initial team we layed the foundation for our innovative insurance company, spotted our talented team and grew an innovative and integrated organization with a healthy people and performance oriented culture. I worked on board level and as an executive manager I shaped all aspects of ELEMENT until the successful Series A financing round and stayed close until it was ready to succeed without me.
Bertelsman - Interim Chief Technology Officer
I ramped up the engineering org of a new venture focusing on data-driven product discovery in the field of media streaming. We created prototypes and concepts eventually resulting in a re-organization and change of strategy for the established units.
I had the pleasure to work at Element while Henning was the CTO. Although he was several steps above me, I always found him truly approachable and immensely candid. Whenever I asked him he spoke openly about his learnings,successes and failures at tech management and gave me invaluable advices,both professionally and personally. I count my self lucky as a young professional for having the chance to dip into someones knowledge with such a diverse and high-profile project portfolio.Károly Kemény

I worked with Henning during our time at FinLeap. Henning is a greatCTO with the perfect balance between "can do" attitude and actually deliveringwhat he promises. His solutions were both set up fast and rock solid. Greatleader and builder. Would certainly love to work with him again.Mark Bothorn
I had the pleasure to work with Henning at a large project where hewas Co-CTO, and I was a developer. Henning has both strong leadershipskills and very good technical understanding - a combination that is rareto find in my experience. He also has experience in facilitating the scalingof agile processes for fairly large development teams, where he could strikethe balance to share his opinion and leave autonomy to the teams.I wish Henning all the best :-)Andreas Profous

Henning is one of the most inspiring, motivating, knowledgeable and talented CTOs I have come across in my career. I have worked very closely to Henning since Element insurance began its operations. I was one of the first hires within the software development team, reporting directly to Henning. Since the very beginning, I have loved every single minute of working in Henning’s team. Not only he was able to create the right working environment, but also systematically made the perfect hiring decisions,… Read moreSimon Aquino
7 ways to kill your business (as a cto)
As an interim-CTO, consultant, coach and advisor I have a chance to work with a lot of companies. Being part of CTO-networks I hear about even more. I got gradually aware of a few dangerous patterns, which I saw repeatedly ever since I started my career. Sometimes, these technical management traps are unavoidable. Sometimes, the mistakes pile on top of each other and create a highly dysfunctional climate in organisations. This in turn causes smart people to struggle in their roles and shifts the path of the organisation away from actually creating value.Read more
