What Ceto does
Ceto (legally Ceto AI Limited, formerly CetoAI) is a Newcastle upon Tyne-headquartered maritime technology company that builds an AI-powered platform to convert high-frequency vessel sensor data into predictive maintenance, emissions management, and data-driven marine insurance outputs. The core product, Watchkeeper, processes approximately 90,000 JSON documents per vessel per day, each containing around 100 distinct time-series measurements from engines, generators, and critical machinery, using ML models built on PyTorch and Scikit-Learn and stored in MongoDB Atlas time-series collections. Watchkeeper detects anomalies up to 96 hours before equipment failure and is complemented by CarbonID, an emissions management platform aligned with EU ETS compliance, and Connected Insurance, which links operational data to risk-adjusted insurance premiums. The company also operates as a Lloyd's coverholder Managing General Agent in partnership with Chaucer Group and Tokio Marine Kiln, authorized to bind marine hull risks using real-time vessel data.
Ceto serves commercial ship owners, technical managers, operators, charter parties, and marine insurance buyers, with an active customer and partner base across Japan, Singapore, and the UK. Its go-to-market combines direct enterprise field sales (demo-based, CEO-led) with insurance channel partnerships through Howden, Chaucer, and a panel of seven A-rated insurance carriers, plus a self-service monthly subscription for CarbonID. The company has raised approximately £1.5M in pre-seed funding (October 2023, led by Howden Ventures) and $4.8M in seed funding (April 2025, led by Dynamo Ventures) from a syndicate including Howden Ventures, Signal Ventures, Motion Ventures, Chaucer, Founders Factory, and Business Investors Group. Founder and CEO Tony Hildrew brings over a decade of maritime engineering and fleet management experience, supported by CTO Ben Harrison and Chief Underwriting Officer Bob Clarkson (30+ years in marine insurance including the Lloyd's market). Revenue mechanics span SaaS subscriptions (Watchkeeper, CarbonID), insurance premiums via the Lloyd's MGA, and transaction-based fees for connected insurance underwriting.

Ceto competitors and assessment
Company assessmentBroad incumbents
- Wartsila: Finnish marine and energy OEM offering SmartShip and Smart Maintenance solutions with condition monitoring, voyage optimisation, and emissions analytics across a global installed base. Closest large-scale incumbent in integrated vessel data analytics and the most likely bundled competitor to Ceto's Watchkeeper and CarbonID.
- Kongsberg Maritime: Norwegian marine technology incumbent providing ship automation, navigation, sensors and integrated digital solutions to commercial shipyards and operators. Comparable because of broad installed-base condition monitoring and digital fleet offerings targeting similar ship-owner and technical-manager buyers.
- ABB Marine & Ports: Global marine automation and electrification supplier with vessel control systems, ABB Ability remote diagnostics, and emissions/energy optimisation. Directly comparable to Ceto's automation, sensor monitoring and emissions use cases at large-vessel scale.
- Ocean Technologies Group: Broad maritime digital solutions provider covering e-learning, crew management, operational software and fleet optimisation for shipowners. Comparable as a wider-portfolio incumbent selling adjacent digital tools to the same shipowner/technical-manager personas.
Direct peers
- Concirrus: London-based marine insurtech that uses behavioural data analytics and AI to underwrite marine hull and cargo risk. Most direct comparable to Ceto's Connected Insurance and MGA thesis - same maritime insurance-buyer customer, same data-driven underwriting angle.
- StormGeo: Norwegian provider of weather routing, vessel performance and emissions management software used by shipowners and operators. Closely comparable to Ceto's CarbonID and the fuel/efficiency portion of Watchkeeper from a software-product perspective.
- RightShip: Maritime risk and ESG intelligence platform used by charterers, shipowners and banks to evaluate vessel safety and emissions performance. Comparable on the data-driven risk-assessment and ESG/emissions use cases that underpin Ceto's Connected Insurance value proposition.
Emerging players
- NAPA: Finnish ship operations and design software specialist offering voyage optimisation, stability and fleet intelligence tools. Comparable to Ceto on the operational-analytics and emissions-optimisation side for shipowner/operator buyers.
- Veson Nautical: Provider of maritime freight management, IMOS platform and voyage data analytics to commercial shipping operators. Comparable because of the data-platform approach to fleet performance and maritime commerce workflows serving similar owner/operator buyers.
Others
- Spire Maritime: Satellite-AIS vessel tracking and maritime data provider serving commodity traders, shipowners and government agencies. Comparable as a maritime data infrastructure player whose dataset is complementary - and partially competitive - to Ceto's sensor-data layer for analytics and risk.
