KOHTARI LIMITED

What KOHTARI LIMITED does

Kohtari Limited is a UK-based water intelligence company that builds AI-powered water quality monitoring solutions for water utilities, with a registered office at 1 Bartholomew Close, London EC1A 7BL (company number 16514422). Its platform combines automated drone-based sampling, IoT sensors, robotics, and AI-driven analytics to deliver both real-time water quality data and forward-looking risk prediction across reservoirs, coastal sites, and hard-to-reach locations. Three core product lines anchor the offering: Drone-Enabled Water Quality Monitoring, a managed service using the patent-pending Kingfisher Grab Sampler and an optical sonde capturing up to 27 water quality parameters; Coastal Water Quality Intelligence, a scalable monitoring network combining drones, sensors, Lab-in-a-Box shore-side testing, and a digital Chain of Custody reporting layer; and BloomIQ, an AI-powered algal bloom predictive intelligence platform. The flagship programme, Smart Skies, Healthy Waters, is a £7M Ofwat-funded world-first coastal water quality initiative running two months ahead of schedule and anchored by Northumbrian Water with Southern Water, South West Water, United Utilities, and Essex and Suffolk Water as consortium participants.

The business model blends managed services (drone-led monitoring and sampling), subscription (BloomIQ platform access), and grant/professional services revenue via the Ofwat programme. Go-to-market is enterprise field sales targeting UK water companies and regulators, supported by direct demo requests, participation in innovation festivals and demo days, and a content-marketing presence on the company website and LinkedIn. Pricing is quote-based with custom multi-year contracts; pricing is not publicly disclosed. Strategic ecosystem partners include Microsoft (Azure AI platform partnership announced 2025-11-12), Skyports Drone Services, Proteus Instruments, Tharsus (robotics), Newcastle University, and Stream: Unlocking Water Data. The company has won the Water Breakthrough Challenge and was shortlisted for Best Real-Time Water Quality Monitoring Project at the Environmental Monitoring Awards 2025.

The leadership team comprises CEO James Sumsion (20+ years scaling technology businesses), CTO Stuart Evans (digital transformation), Chair Joe Wolski (also CTO at Godel Technologies), Non-Executive Director Matt Franklin (formerly at Roc Technologies), Board Member Trevor Rolls (30+ years in IT, investor background), and International Strategic Adviser Lord Anthony St John of Bletso (former House of Lords member, AI Select Committee alumnus, appointed March 2026 to support international growth). No equity funding rounds, revenue, ARR, or headcount figures have been disclosed.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Hach (Danaher): Established global supplier of water quality sensors, probes, reagents and laboratory instruments serving municipal and industrial water users. Hach competes with Kohtari on the instrumentation side (sonde-style multi-parameter sensing) but does not offer drone-enabled sampling or UK-specific algal-bloom predictive AI.
• Xylem: Global water technology incumbent offering analytics, smart metering and water quality solutions to utilities worldwide. Xylem overlaps with Kohtari across water quality instrumentation and AI/analytics for utilities, but operates at vastly larger scale with a broad portfolio beyond drone-enabled sampling.
• Veolia Water Technologies: Global water services and technology provider serving municipal and industrial clients with treatment, monitoring and digital solutions. Veolia competes for the same UK water-utility digital budgets as Kohtari but as a broad incumbent with a much larger solutions portfolio.
• Suez Water Technologies & Solutions: Global water services and digital solutions provider with a strong presence in UK municipal water and industrial treatment. Suez competes with Kohtari for digital monitoring budgets within UK utilities, but as a large diversified incumbent.

Direct peers

• StormHarvester: UK- and Ireland-based AI startup applying machine learning to urban water networks for real-time decision support and event prediction. StormHarvester directly parallels Kohtari's AI-for-water proposition within the same UK utility buyer base, but focuses on network/flow analytics rather than water-quality sampling.
• i2O Water: UK-headquartered provider of smart water network management solutions for leakage, pressure and demand optimisation at utilities. i2O shares Kohtari's UK enterprise water-utility buyer base and recurring software/data sales motion, but its focus is network optimisation rather than water quality monitoring.
• Ovarro: UK-based provider of remote telemetry, monitoring and analytics for water and other utilities, including water network event detection. Ovarro directly overlaps with Kohtari on UK utility-focused remote monitoring hardware + analytics, though its emphasis is on network telemetry rather than water quality or algal blooms.
• Syrinix: UK-based water network monitoring specialist using sensors and analytics to detect leaks, pressure events and pipe failures in real time. Syrinix is a direct comparability match for Kohtari on UK-centric, sensor-plus-analytics water monitoring, though its domain is pipelines rather than quality/bloom prediction.

Emerging players

• FIDO Tech: UK-based AI company using acoustic sensing and machine learning to detect and locate water leaks in real time for utilities. FIDO Tech shares Kohtari's UK AI-for-water utility positioning and event-driven go-to-market, but addresses leakage rather than water quality.
• Inflowmatix: UK-based water analytics startup providing high-resolution hydraulic and network analytics for utilities. Inflowmatix overlaps with Kohtari in UK AI-for-water utility sales, but focuses on flow/hydraulic analytics rather than water-quality or algal-bloom prediction.
