Revenue model
- Underwater Drone Hardware Sales: FullDepth sells industrial underwater drone products (DiveUnit KAI, 300 Lite, HAYATE) and associated accessories and options. Hardware is the primary revenue driver, with products sold directly to enterprises, government agencies, and research institutions. Pricing is quote-based and varies by configuration.
- Inspection and Survey Services: FullDepth provides underwater inspection services using their own drones operated by trained personnel. This service allows customers who have not purchased equipment to access underwater inspection capabilities, providing a recurring service revenue stream alongside hardware sales.
- FullDepth Bridge Cloud Service: FullDepth Bridge is a cloud platform that stores, views, and downloads underwater inspection data collected by drones. While currently offered free, the service enables remote video sharing, data analysis, and inspection reporting, positioning it as a potential future SaaS revenue stream.
- Underwater 3D Measurement Services: FullDepth offers specialized measurement services including 3D point cloud capture and 2D/3D wall surface imaging using proprietary drone-based sonar and photogrammetry techniques, sold as new underwater digitalization inspection services.
- AUV-based Inspection Solutions: As FullDepth develops AUV technology, they are building toward autonomous inspection solutions for offshore wind power O&M, combining ROV, ASV, and AUV data collection with cloud analytics for the marine data space concept.

FullDepth competitors and assessment
Company assessmentDirect peers
- ECA Group: ECA Group manufactures ROVs, AUVs, and autonomous underwater systems for defense, offshore, and hydrography applications. Comparable to FullDepth's industrial ROV/AUV portfolio and government/defense customer base, particularly in the AUV development space.
- Kongsberg Maritime: Kongsberg manufactures HUGIN AUVs and subsea inspection platforms for offshore energy, hydrography, and defense — overlapping directly with FullDepth's ROV/AUV product lines and target applications. Operates globally with substantially greater resources and a more mature AUV fleet.
- DeepOcean: DeepOcean provides subsea inspection, maintenance, and repair services using ROVs for offshore energy and infrastructure — directly comparable to FullDepth's inspection services business model and offshore wind customer segment, though operating primarily in the North Sea.
- VideoRay: VideoRay produces small-to-medium inspection ROVs for infrastructure (dams, ports, bridges), defense, and public safety — directly overlapping with FullDepth's DiveUnit product family and customer segments, particularly dam and harbor inspection.
- Deep Trekker: Deep Trekker manufactures compact, portable industrial ROVs for infrastructure inspection, search and rescue, and aquaculture — directly comparable to FullDepth's DiveUnit 300 Lite and HAYATE in product positioning, target customers, and portability-focused design philosophy.
- Saab Seaeye: Saab's marine robotics division manufactures industrial ROVs (Falcon, Sea Wasp, Sabertooth) for inspection, defense, and offshore applications. Directly comparable to FullDepth in ROV product design, target customers (infrastructure inspection, defense, offshore energy), and depth ratings — though serving a global market rather than Japan-only.
- Ocean Infinity: Ocean Infinity operates one of the world's largest fleets of unmanned underwater vehicles for offshore survey, inspection, and seabed mapping — directly comparable to FullDepth's AUV-based inspection roadmap for offshore wind O&M and marine data services.
Broad incumbents
- Fugro: Fugro is a global geodata specialist operating ROVs and AUVs for offshore survey, seabed mapping, and infrastructure inspection — directly comparable in service offering and offshore energy customer base, though as a much larger established player with global reach.
- Teledyne Marine: Teledyne Marine is a portfolio of subsea vehicle, sensor, and imaging brands (including SeaBotix and Gavia AUV) serving offshore inspection, hydrography, and research markets. Directly comparable ROV/AUV product family though part of a much broader marine technology conglomerate.
Emerging players
- Chasing Innovation: Chasing Innovation manufactures consumer and prosumer underwater drones (M2, Dory) for inspection and exploration. While more prosumer-oriented than FullDepth's industrial DiveUnit line, there is meaningful overlap in target use cases (aquaculture, hull inspection, search and rescue) and the underlying drone hardware technology.
