Our Vision
We're building
the ears of the ocean.
Illegal fishing destroys marine ecosystems faster than they can recover. Ocean Sentinel listens where satellites can't see — turning acoustic signals into real-time intelligence for the people protecting our oceans.
The problemUp to 26 million tonnes of fish are taken illegally every year — nearly a third of the global catch. Most goes undetected.
Our approachPassive acoustic monitoring at scale. Every hydrophone is a 24/7 sentinel. The CNN flags anomalies in milliseconds; Gemma 4 reasons over the evidence.

The People
Two engineers.
One mission.
Jakub
Machine Learning · Signal Processing
Machine learning engineer with a focus on AI. Built the Ocean Sentinel CNN from scratch — 2.5M parameters, 96.4% detection accuracy.
Matt
Product · Systems · Design
Works across systems, design, and product. Architected the data pipeline, built the live dashboard, and shaped the full product experience from the ground up.
