# 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.

- **Founded:** 2022
- **Headquarters:** Cambridge, Massachusetts, United States
- **Founders:** Ravi Pappu (Founder & CEO)
- **Team size:** 16
- **Products:** Tensor, Apeiron AUV, Ocean Data Cloud
- **Notable:** Closed a $9.5M Series A in February 2026 co-led by S2G, RA Capital's Planetary Health Fund, and DYNE Ventures., Reports a ~100-fold reduction in the cost of ocean data at current scale, with a roadmap to 1,000-fold., Secured multiple U.S. government contracts for its ocean-sensing technology.

## Products & services

- **Tensor** — An ocean data platform built on large, cost-effective networks of small, persistent, autonomous underwater vehicles (AUVs). It delivers autonomous observing across the upper 400m of ocean, low cost per data point, station-keeping persistent sensing, and ocean data as a service.
- **Apeiron AUV** — A roughly 3-foot-long, 5-inch-diameter autonomous underwater vehicle weighing just over 20 pounds. It travels up and down the top 400m of the water column, sampling temperature, salinity, and acoustics once or twice daily, deployable from boats or aircraft and compatible with U.S. Navy launch equipment.
- **Ocean Data Cloud** — A cloud-based operating system that logs, standardizes, and models sensor data, delivering real-time ocean intelligence to customers.

## Achievements

- Closed a $9.5M Series A in February 2026 co-led by S2G, RA Capital's Planetary Health Fund, and DYNE Ventures.
- Reports a ~100-fold reduction in the cost of ocean data at current scale, with a roadmap to 1,000-fold.
- Secured multiple U.S. government contracts for its ocean-sensing technology.
- Built a reusable, mass-producible AUV deployable from both boats and aircraft and compatible with U.S. Navy launch systems.
- Resident company at The Engine, MIT's tough-tech incubator.

## Latest updates

- **2026-02** — Closed $9.5M Series A to scale its global ocean data platform, co-led by S2G, RA Capital's Planetary Health Fund, and DYNE Ventures.
