Apeiron Labs
Apeiron Labs is a Cambridge, Massachusetts deep-tech company building the Tensor platform - large, low-cost networks of small autonomous underwater vehicles that persistently measure the upper 400 meters of the ocean. By making subsurface ocean data cheap and continuous instead of episodic and expensive, Apeiron sells real-time ocean intelligence as a service to defense, climate, offshore energy, aquaculture, and maritime customers. The company raised a $9.5M Series A in February 2026 and says it has already cut the cost of ocean data roughly 100-fold, with a goal of 1,000-fold.
