Neptune Zero has secured a €500,000 investment to accelerate the development of its maritime sensor data-driven reporting solution and enhance real-time fleet performance.
Athens, 06 May 2026 – Neptune Zero, a Greek deep-tech company developing AI-powered solutions for vessel performance optimization and automated maritime reporting, announces the completion of a €500,000 seed investment round.
The round was led by Corallia Ventures TT AKES, with participation from angel investors.
AI-driven automation and optimization for global shipping
Neptune Zero is building a modular ecosystem including a platform that combines onboard hardware, edge computing, and cloud-based analytics to automate vessel reporting and optimize fleet performance in real time.
The platform collects and validates operational data using AI algorithms, automatically generates daily reports, and provides real-time fleet analytics, eliminating manual processes and enabling data-driven decision-making across shipping operations.
By replacing error-prone and time-consuming noon reporting workflows, Neptune Zero significantly reduces administrative burden while improving data accuracy and compliance.
Delivering measurable impact: fuel savings, cost reduction and compliance
Neptune Zero’s solution delivers immediate and quantifiable value for shipping companies:
- ~3% reduction in fuel consumption and emissions
- ~€100k+ annual savings per vessel on average
- ROI achievable in approximately 6 weeks
- Improved CII ratings and reduced regulatory exposure
In fleet-level deployments, Neptune Zero has demonstrated:
- ~$574k annual fuel savings across a 5-vessel fleet
- Additional savings from reduced EU ETS exposure
- Enhanced operational transparency and decision-making
Strong early traction in a growing $700 Billion market opportunity
Neptune Zero is already gaining significant commercial traction:
- €1 million in contracted value
- Deployment across 100+ vessels
- Partnerships with leading Greek & international shipping companies
The company operates in a global maritime ecosystem undergoing rapid digital transformation, driven by decarbonization targets, regulatory pressure (EU ETS, FuelEU Maritime, IMO DCS), and rising fuel costs.
With the global merchant fleet exceeding 100,000 vessels and the Marine IoT market projected to reach $689 billion, Neptune Zero is positioned at the forefront of a large and expanding opportunity.
