SI Robotics

SI Robotics is a Warsaw humanoid robotics startup founded in 2024 by Patryk Szymczak and Kajetan Andrzejewski. It is developing a fully European humanoid platform with high-torque bionic actuators and control based on reinforcement learning, aimed at industrial and defense applications.

In July 2025 the company raised pre-seed funding from Sunfish Partners, a VC fund operating in Berlin and Warsaw; the money is earmarked for actuator research, hiring engineers and launching early production in Poland.

It is one of the few projects building a humanoid from scratch with a European supply chain, rather than relying on components from China or the US, which could be an asset in defense contracts that require technological sovereignty. At this stage the robot is still in development, with no publicly available technical data or product launch date.
