Our Mission
To provide the most advanced subsea data collection through autonomous robotic platforms, reducing human risk and operational overhead.
A data company first,
a robotics company second.
Mare Custos offers offshore operators structured, geo-referenced datasets through in-house built technology.
PURPOSE & DIRECTION
Transforming subsea inspection with structured data
We don't just capture what's down there — we turn every dive into decision-ready data. Here's what guides how we build and operate.

Our Vision
A future where marine operations are entirely data-driven, leveraging AI to predict and prevent infrastructure failures before they happen.
Who We Are
Robotics engineers and subsea NDT specialists, headquartered in Plouzané, Brittany, operating across France, Tunisia, and Saudi Arabia.
COMMON CHALLENGES
Built to solve what asset owners face
Safe and cost-effective alternatives to human saturation diving at depths exceeding 100 meters are rare. Our autonomous units provide risk-free data collection in extreme environments without the need for life support systems.
Corrosion, fatigue cracks, and coating breakdown progress unseen below the waterline. Continuous, structured inspection surfaces degradation early — before it becomes failure.
Mobilizing dive teams and support vessels is slow and expensive. A single modular platform captures the same data in a fraction of the time and cost.
Raw footage leaves gaps. Every dive returns geo-referenced, structured findings, so nothing critical goes unrecorded or unreviewed.
