Y Combinator Demo Day shifts focus toward deep tech

The recent Y Combinator Demo Day has signaled a strategic shift toward deep tech, with startups focusing on physical infrastructure and hardware to address artificial intelligence bottlenecks. Investors noted that valuations for this cohort appear more grounded and realistic compared to previous years driven by software hype.

Key innovations highlighted include Automarine, which proposes floating data centers powered by nuclear energy to solve cooling and power supply issues, and Dipole Labs, which develops optical networking hardware to improve AI cluster efficiency. The robotics sector also saw significant activity, with Nori aiming to provide affordable humanoid robots and Cosmic Robotics focusing on heavy-duty automation for space colonization. Other notable developments include Waddle Labs’ natural language API for robot control and Isengard Industries’ low-cost jet-powered drones.
