What KETOS does

KETOS is a vertically integrated water intelligence company that builds patented IoT sensors, robotic self-cleaning instrumentation, cloud analytics, and a REST API to deliver continuous, real-time water quality monitoring across more than 30 parameters, including heavy metals, nutrients, pH, turbidity, and PFAS-related indicators. Its flagship KETOS SHIELD platform uses EPA-approved testing methodologies certified to deliver results within ±10% of certified laboratory accuracy, replacing legacy manual grab sampling with always-on measurement for municipal water utilities, industrial process water, energy generation, agriculture, and mining customers. The portfolio extends to KETOS WAVE (self-powered flow/pressure/volume efficiency monitoring), KETOS PRISM (PFAS and environmental risk data platform), KETOS Analytics (predictive intelligence and reporting), and KETOS KELP (in-house certified environmental lab services).

The business operates on a $0 CAPEX, all-inclusive monthly subscription (Data-as-a-Service) model that bundles hardware, software, connectivity, alerts, reporting, and predictive analytics into a single operating expense, removing the upfront capital barrier that has historically limited continuous monitoring adoption among municipalities and mid-market industrial users. KETOS sells primarily through a direct enterprise field sales motion targeting municipal water authorities, Fortune 500 manufacturers, and energy operators, with inside sales supporting mid-market accounts and channel partnerships (notably WaterStart/SNWA) extending reach into regional US markets. The company reports a deployed footprint spanning 6 countries and 27 US states, with over 29 billion gallons of water monitored and 255 million+ data insights generated across the platform.

KETOS is venture-backed (privately held, headquartered in Sunnyvale, California) and has raised approximately $48M+ across multiple equity rounds since 2017, including a $9M Series A (2019), a $15M growth round (2020), a $10M Tenfore-led growth round (2021), an $18M Series B (2022), and a €9M Tenfore-led growth round in 2024 with participation from Accenture, Broadway Angels, Danu Venture Group, Plum Alley Ventures, and Plug and Play Ventures. The company's stated strategic focus is on expanding its global presence and PFAS monitoring capabilities, evidenced by 2025 product launches (PRISM, KELP) and high-visibility international deployments including the Maha Kumbh Mela in India.

Revenue model

1. SaaS Subscription — Data-as-a-Service: KETOS operates a recurring subscription model under a Data-as-a-Service (DaaS) framework. All-inclusive monthly fees cover hardware (sensor devices), software (cloud platform and analytics), connectivity, reporting, automated alerts, and predictive analytics. No upfront CAPEX is required from customers; the entire solution is delivered as an operational expense. This model provides predictable recurring revenue with land-and-expand potential as customers add monitoring locations or parameters.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Xylem: Global water technology major owning Hach, Sensus, and other brands spanning water quality instrumentation, smart metering, and utility-scale solutions. Overlaps directly with KETOS across municipal and industrial water quality monitoring but operates as a broad incumbent with a much larger portfolio and global service footprint.
• Hach: A Xylem-owned brand and a long-standing leader in lab and process water quality instrumentation, including spectrophotometers, sensors, and reagents. Compares to KETOS SHIELD on multi-parameter water quality measurement but primarily delivers bench/lab instruments plus conventional online probes rather than a zero-CAPEX IoT SaaS model.
• Veolia Water Technologies: Major water services and technology provider offering monitoring, treatment chemicals, and digital solutions to municipal and industrial customers. Overlaps with KETOS on industrial and municipal water quality monitoring but bundles hardware, services, and chemicals rather than selling a pure IoT subscription.
• Itron: Global smart metering and utility analytics provider with a water-focused portfolio of meters, AMI networks, and data analytics platforms. Overlaps with KETOS WAVE on flow/pressure/volume monitoring and with KETOS's broader municipal data platform play.
• Mueller Water Products: Manufacturer of water infrastructure products including smart meters, hydrants, valves, and pipe condition monitoring. Comparable to KETOS in serving US municipal water utilities with monitoring and measurement technologies, though Mueller is primarily a hardware manufacturer rather than a SaaS data platform.

Direct peers

• Endress+Hauser: Global manufacturer of industrial process instrumentation including liquid analysis sensors (pH, conductivity, turbidity, dissolved oxygen) and supporting automation. Directly competes with KETOS in industrial process water quality monitoring and shares the multi-parameter sensor approach, though Endress+Hauser's model is hardware-led rather than subscription.
• Aclara (Hubbell): Smart infrastructure provider for electric, gas, and water utilities, including AMI metering and sensor solutions. Directly comparable to KETOS on smart water monitoring and data analytics for municipal utilities, with overlapping customers in the US water utility segment.
• Kamstrup: Danish manufacturer of smart metering and water quality monitoring solutions for utilities, including multi-parameter sensors and analytics software. Directly comparable to KETOS on continuous water quality monitoring and smart water data platforms, with strong European utility exposure.

Emerging players

• Libelium: IoT sensor platform provider for environmental monitoring including water quality, agriculture, and pollution. Comparable to KETOS at the IoT sensor layer (multi-parameter water probes, cloud connectivity) but more focused on the sensor hardware/platform licensing model rather than end-to-end vertical SaaS.
• Sensoterra: Niche IoT sensor company offering soil moisture and water quality probes primarily for agriculture and smart-city applications. Partially comparable to KETOS in agriculture and irrigation monitoring, though Sensoterra is smaller and more focused on soil/sub-surface moisture than full multi-parameter water chemistry.
