Apeiron Labs (APEI) Secures $29M to Scale Autonomous Underwater Data Collection Fleet

Apeiron Labs (APEI) closed a $29 million Series A funding round to accelerate deployment of its low-cost, autonomous underwater vehicles (AUVs). The AUVs, about three feet long and weighing under 20 pounds, sample temperature, salinity, and acoustics across the water column at 400-meter depths, spaced 10–20 km apart to provide high-resolution ocean data. The round, led by Dyne Ventures, RA Capital Management Planetary Health, S2G Investments, Assembly Ventures, Bay Bridge Ventures, and TFX Capital, enables mass production and integration with the U.S. Navy’s existing launch systems. The company currently serves both civilian and defense customers and aims to reduce ocean data costs by a factor of 1,000 from today’s $100 per unit, targeting a 100-fold improvement by next year. Data is logged to a cloud-based operating system that refines ocean models, enabling persistent monitoring for fisheries, the Coast Guard, offshore wind, and national security applications.
