Demo Day 2026

This event is open to investors only - registrations are subject to approval Welcome to Silicon Allee's Demo Day, an investor-only event showcasing deep tech startups from the venture lab at Fraunhofer HHI, one of Germany's leading research institutes. Hear pitches from AI, quantum, real estate, education, medical, bio, defense and communication startups from our venture lab at Fraunhofer HHI. You'll meet our startups at a rare stage. For the past one to two years, they've been building inside Fraunhofer HHI, developing their technology alongside world-leading researchers, with access to exclusive IP and patents most companies never get near. Our unique support gives them a technical moat over competitors, and they already have early traction from customers. On top of that, our startups come with clean cap tables. We use virtual shares instead of equity, so ownership stays with the founders as they grow. What to expect: An interactive livestream will be made available for investors who cannot travel to Berlin. But, to get face-to-face with the founders first, we do recommend being in-person. Food and drinks provided.
