Apeiron Labs announced it has closed a $9.5 million Series A financing to scale its real-time ocean intelligence platform and expand deployments of its autonomous underwater vehicle networks. The Cambridge, Massachusetts-based company said the round was co-led by S2G Investments, RA Capital Management’s Planetary Health Fund, and DYNE Ventures, with participation from Assembly Ventures, TFX Capital, and Bay Bridge Ventures.
Founded in 2022, Apeiron Labs is building a global ocean data platform designed to deliver persistent subsurface observation at a fraction of traditional ocean-monitoring costs. The company positions its approach as applying “CubeSat thinking” to the ocean, using low-cost, mass-produced AUVs equipped with oceanographic sensors to collect upper-ocean data, which is processed, standardized, and delivered to customers as real-time intelligence.
Apeiron Labs said the financing will accelerate development of its data platform and support broader global deployments. The company also plans to expand its technical and commercial teams as it deepens customer partnerships across government and commercial markets.
The company highlighted ocean observation as a major gap in global monitoring, noting that while satellites provide near-real-time atmospheric data, ocean data collection has historically been slower, sparser, and more expensive. Apeiron Labs said it has already secured multiple contracts from U.S. government agencies to operationalize its technology across a range of missions, and it framed its data streams as enabling improved modeling and situational awareness for users operating in environments with limited sustained visibility.
In addition to defense and intelligence applications, Apeiron Labs said its platform supports commercial use cases including offshore energy, maritime logistics, insurance, and climate services, helping customers improve risk management, operational planning, and regulatory compliance as ocean conditions become more volatile.
The company’s core offering is its Tensor platform, which it says lowers the cost and carbon footprint of acquiring upper-ocean data while enabling persistent, autonomous observation networks for ocean-dependent sectors.
KEY QUOTES
“The atmosphere has its satellite constellations. The ocean needs its own. We’re applying CubeSat thinking to ocean observation through a data platform designed for continuous insight at a scale that matches the scope of the challenge. This financing enables us to accelerate development of our data platform and expand global deployments of our AUV networks.”
Ravi Pappu, Co-Founder and CEO, Apeiron Labs
“We believe Apeiron Labs is tackling one of the most critical blind spots in the global economy. The team pairs deep technical experience with a disciplined approach to building a commercially viable data platform, demonstrating that ocean observation can scale in an economically sustainable and operationally impactful way.”
Sanjeev Krishnan, Managing Partner, S2G Investments; Co-Founder, Apeiron Labs
“The defense and intelligence communities have long understood the value of distributed, low-cost sensing platforms in space. Apeiron Labs is bringing that same paradigm shift to maritime domain awareness. Ravi and the team have built what we believe is the lowest cost-per-data-point solution in ocean observation – offering scalable, persistent ISR capabilities with clear national security relevance. We’re excited to support Apeiron Labs alongside S2G and RA Capital’s Planetary Health Fund.”
Matthew Kibble, Managing Partner, DYNE Ventures
“As climate volatility increases, the ability to observe and understand ocean conditions in real-time will be essential across multiple critical industries. We’re proud to back this team as they scale a platform that will reshape how ocean-dependent sectors operate.”
