Based in Kaunas, Lithuania, Thunderclap Labs is an advanced engineering startup. We build physical hardware and AI-driven systems from the ground up, skipping the bureaucracy in favor of rapid prototyping, aggressive testing, and vertical integration.

Our expertise spans comprehensive R&D services, reusable rocket propulsion, artificial intelligence, in-house propellant synthesis, and active autonomous defense tracking (Thunder Eye). We partner with ambitious organizations to turn complex challenges into functional hardware. We don't just design theories; we manufacture reality.
