Taavi Madiberk

Non Executive Chair and co-founder @ Frankenburg Technologies

About

I work on building technology companies focused on power, hardware, and large-scale industrial systems. I have co-founded three deep-tech companies with a combined valuation exceeding €1 billion, operating across AI infrastructure, energy systems, and defense. I am CEO & Co-Founder of Skeleton Technologies, where we focus on what has become the binding constraint for AI deployment: power. Compute is no longer the bottleneck. Models scale. Chips are available. Power is not. Skeleton designs, manufactures, and deploys mission-critical power systems for AI data centers, modern grids, and defense - enabling reliable operation of AI, grid, and defense systems under real-world constraints. In parallel, I am Co-Founder & Chairman of the Board of Frankenburg Technologies (advanced air-defense systems) and Stargate Hydrogen (next-generation electrolyzers). I spend most of my time scaling teams, factories, and deployments across Europe, the U.S., and the Middle East. Across these companies, the pattern is consistent: when systems are power-constrained, safety-critical, and must be deployed at scale, winning requires mastery of hardware, physics, and manufacturing.
