KETOS, based in Milpitas, California, develops a vertically integrated platform for automated water quality testing and monitoring, utilizing intelligent hardware, bi-directional connectivity, and software to detect over 30 parameters in real-time. This system automates traditionally manual processes for leak detection, alerts, reporting, and predictive analytics, offered as a subscription-based service with a predictable flat fee and $0 CAPEX. The platform serves industrial, agricultural, and municipal water operators, enhancing efficiency and safety for customers, and currently employs 60 individuals. The company reported $16.3 million in revenue and has partnered with Siemens to provide comprehensive water quality solutions. KETOS recently announced its Environmental Lab Platform (KELP) for certified lab testing, launching in May 2025 with PFAS testing services, and was founded in 2015.
KETOS has raised $40.0M across 4 funding rounds.

KETOS is a technology company providing a vertically integrated water intelligence platform that combines robotics, IoT sensors, data science, AI, and predictive analytics for automated, real-time water quality monitoring and testing.[1][2][4][5] It serves industrial sectors (e.g., oil & gas, mining, manufacturing, paper & pulp), controlled agriculture, and municipalities/federal entities, solving critical challenges like water efficiency, contamination detection (including PFAS), compliance, leak detection, and predictive maintenance with parts-per-billion accuracy.[1][2][3][4][5] The platform offers a $0 CAPEX model with flat annual service fees covering hardware (KETOS SHIELD and WAVE), software, connectivity, reporting, alerts, and maintenance, enabling process optimization, risk mitigation, and reduced emissions.[4][5] KETOS has raised over $39M in funding, built a 170M data point lake, and operates in 10+ regions across 21 US states and internationally, with recent launches like KETOS PRISM and partnerships such as Siemens.[1][2][5]
Founded in 2015 in Sunnyvale, California, KETOS was established by Meena Sankaran, whose mission centered on empowering communities with safe water access through simplified testing and operational efficiency.[1][2] The idea emerged at the intersection of growing water scarcity, regulatory pressures, and the need for real-time intelligence in fragmented water management, evolving from basic IoT monitoring to a full-stack platform integrating patented robotics (SHIELD and WAVE devices) with AI-driven software.[2][4] Early traction included building the first comprehensive water quality database and securing diverse cleantech investors, leading to deployments in industrial, ag, and municipal sectors; pivotal moments feature 2024's KETOS PRISM launch for PFAS insights and 2025 partnerships like Siemens for global AI-robotics water solutions.[1]
KETOS rides the wave of digital water transformation, addressing global water crises amid climate change, urbanization, and strict regulations on contaminants like PFAS, where traditional lab methods fall short on speed and cost.[1][2][5] Timing aligns with IoT/AI proliferation in sustainability tech, enabling predictive maintenance and efficiency in a $1T+ water market strained by scarcity—market forces like ESG mandates and industrial decarbonization favor its real-time, low-capex model.[1][4] It influences the ecosystem by creating the largest water quality database for industry benchmarks, fostering smarter farms/cities/industries, and partnering with giants like Siemens to scale robotics-AI solutions globally.[1][2]
KETOS is poised for accelerated growth through PFAS-focused expansions and strategic alliances, potentially dominating automated water intelligence as regulations tighten and AI adoption surges in cleantech.[1] Trends like edge computing, municipal digitization, and climate-resilient ag will shape its path, with interoperability and data lakes enabling ecosystem-wide influence—watch for international scaling beyond 21 US states and deeper industrial integrations. This positions KETOS as a pivotal player redefining water as a data-driven asset, building on its mission to deliver safe, efficient water worldwide.[2][5]
KETOS has raised $40.0M across 4 funding rounds. Most recently, it raised $10.0M Other Equity in May 2024.
