Vention Unplugged: Demo or It Didn't Happen
Everyone talks about what they're building with AI. Almost no one shows it.
Vention Unplugged returns with a format built to cut through that: real builders, live demos, no slides pretending to be products. Just senior engineering leaders showing what they've actually shipped with AI, and a room ready to ask the hard questions.
This evening is for CTOs and engineering leaders who'd rather see working code than a roadmap slide. Expect real demos, sharp Q&A, a bit of humor, and zero sales pitches. The evening will be hosted by Paul Lunow, CTO at Vention.
🎬 Live Demos
Each speaker gets 5 minutes to show something real they've built - an internal tool, a product feature, a workflow that actually changed how their team works - followed by 10 minutes of Q&A where the room gets to dig in:
⚛️ Christoph Neumaier, AI Product Architect at Proxima Fusion – spun out of the Max Planck Institute for Plasma Physics, now Europe's best-funded fusion startup and scaling fast on an AI-first stack, where simulation does the heavy lifting long before hardware gets built.
🩺 Simon Puxbaumer, CIO of gematik – majority-owned by Germany's Federal Ministry of Health and the agency behind the country's digital health infrastructure, from the E-Rezept to the ePA for 70+ million insured people. Proof that AI has arrived in the public sector, too.
☁️ Ben Trollope, Customer Engineer in the Google Cloud team – helping startups build on Google's data and AI services, with the long game and the resources nobody else has behind him.
