Christian Alexander Schreiber

Christian Alexander Schreiber

Christian Alexander Schreiber is the CEO & Founder and Lead Architect of nVibes, a next-generation European social platform based in Dresden, Germany, built around one central idea: Real Vibe. Real People.

With nVibes, Christian is building a social infrastructure for real human connection — a platform designed not for endless scrolling, but to help people feel less alone, find belonging, build trusted communities and create meaningful moments beyond the screen.

https://nvibes.de brings together social interaction, communities, events, real-world activities and intelligent digital experiences while placing privacy, trust, responsible AI and European digital sovereignty at the foundation of the platform.

With more than 30 years of experience in IT consulting, software architecture, Microsoft technologies and digital transformation, Christian combines deep technical expertise with the perspective of a technology founder building a new digital platform from Europe.

His work focuses on the intersection of human-centered technology, responsible and agentic AI, privacy-by-design, digital identity, platform trust, cloud architecture and European technological sovereignty. He explores how AI and modern platforms can strengthen human interaction instead of replacing it — and how technology can create genuine value when it is designed around people rather than attention.

Christian also speaks about AI-ready Azure architectures, responsible AI adoption, secure digital platforms, agentic systems and the practical realities of turning an ambitious technology vision into a real product.

As an international speaker, he brings together strategic leadership, hands-on architecture and real-world startup experience. His sessions are practical, technically grounded and driven by a clear conviction:

The future of social technology should not be about keeping people on a screen. It should help bring people together.

nVibes — Real Vibe. Real People.
A Social Infrastructure for Real Human Connection.

In 2013, I graduated with a BFA and took my first job as a Junior Graphic Designer at a small, boutique ad agency. While there, my Creative Director warned me to never let anyone find out I could code, because if I did I'd be stuck doing it forever. I ignored his warning; it turns out he was completely right, but I've never been happier.

I currently work as a developer advocate on a wonderful team where I help people build web applications in React, design and maintain their UI component libraries, and desperately attempt to stop back-end devs from writing any more CSS.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2023

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2023.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2023. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 25 thousand unique accepted speakers this year, the 3% is 771. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2023. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
