What ONDILO does

ONDILO SAS is a French IoT hardware company headquartered in Saint-Cannat (near Aix-en-Provence), founded in 2016 by Nicolas Fiorini. The company designs, manufactures in France, and sells the ICO line of floating connected water analyzers for residential swimming pools and spas. The current generation, ICO Pool V2 and ICO Spa V2 (launched in 2024), measures pH, ORP/REDOX, temperature and — on salt-pool versions — TDS once per hour, transmitting readings over Wi-Fi and Bluetooth to a proprietary iOS/Android application that delivers a patented Water Index, weather-aware predictive recommendations and personalized chemical-dosing guidance.

The product architecture combines proprietary sensors, in-house predictive algorithms and a mobile/cloud platform that integrates with Alexa and Google Home smart-home assistants. ONDILO monetizes primarily through one-time hardware sales (€399-€449 per device) via a direct-to-consumer e-commerce storefront and a network of pool-equipment resellers across France and Europe, with an installed-base annuity stream from branded replacement sensors (€99 each), calibration kits and the ICO Smart Core electronic unit (€199). A parallel Ondilo Pro platform (partner.ondilo.com) and dealer portal address pool-maintenance professionals as a secondary segment.

The company operates with a 1-10 employee footprint and has raised approximately $1.14M from Bpifrance, Paca Investissement and Provence Business Angels (2017), supplemented by a Région Sud Investissement participatory loan backed by European funds. The mobile app carries 507 Google Play reviews at 4.5/5, and the company maintains active marketing in more than 20 countries with the app localized in 12 languages. Awards include the 2016 Greentech Innovation laureate (Health and Environment category), the 2017 CES Innovation Award, the Green Tech label, and 2023 best connected pool probe recognition.

Product overview

ONDILO is a French technology company that designs and manufactures the ICO line of connected water analyzers for private swimming pools and spas. The product portfolio centers on two current-generation devices: ICO Pool V2 and ICO Spa V2 (both launched in 2024 as major updates to V1 versions from 2018-2019). These are floating IoT devices equipped with sensors that measure pH, ORP/REDOX, temperature, and TDS every hour, connected via Wi-Fi and Bluetooth to a mobile application that displays a proprietary Water Index and delivers personalized, algorithm-driven recommendations. The ecosystem includes replacement sensors (pH, ORP for chlorine/bromine and salt, TDS), calibration kits, spare parts (Smart Core, lids, sensor caps), and the KCl storage solution. ONDILO also offers a professional dealer platform (Ondilo Pro) and a direct-to-consumer online shop. The company positions itself as combining hardware, software, data analytics, and app services into a unified water management solution.

Direct peers

• Sutro: Sutro makes a connected pool and spa water monitor that tests chemistry and provides dosing recommendations via an app. It targets the same residential pool/spa owner use case as ONDILO with a subscription-based testing cartridge model.
• pHin (Hayward Industries): pHin is a smart pool monitor that measures water chemistry and notifies users via a mobile app, now part of Hayward Industries. It competes directly with ICO in the connected residential pool water monitoring segment and benefits from Hayward's broader pool equipment distribution.
• iopool: iopool offers a connected pool and spa analyzer (Eco Pool Star and Spa Star) that measures pH, ORP/disinfectant, and temperature and sends dosing recommendations to a smartphone app. It is a direct competitor to ICO, particularly across European markets.
• WaterGuru (SENSE by WaterGuru): WaterGuru produces a connected smart pool monitor that continuously measures water chemistry and dispenses chemicals, sold primarily to residential pool owners in North America. It is the closest direct competitor to ICO in the connected pool water analyzer category.

Emerging players

• Beatbot: Beatbot is an emerging smart pool robotics company producing AI-driven pool cleaning robots with app connectivity. It is adjacent rather than directly overlapping, but competes for the same connected backyard ecosystem and consumer mindshare as ICO.
• Aiper: Aiper is a fast-growing consumer smart pool robotics brand offering app-connected pool cleaning devices. It is adjacent in connected pool hardware, targeting the same consumer pool owner and competing for retail shelf space and digital attention.

Broad incumbents

• Pentair: Pentair is a global water treatment and pool equipment company offering pumps, filters, automation, and increasingly connected pool solutions. While not a focused pure-play in connected water analyzers, it competes for the same end customer and pool builder relationships as ONDILO.
• Maytronics (Dolphin): Maytronics is the global leader in robotic pool cleaners (Dolphin brand) and is expanding into broader connected pool solutions. It competes with ONDILO for share of pool-owner wallet and attention in the smart pool category.
• Hayward Industries: Hayward is a major pool equipment manufacturer offering pumps, filters, heaters, and automation systems, and owns the pHin connected monitor. Its broad product portfolio and large dealer network make it a key incumbent competing with ONDILO for both consumers and pool professionals.
• Fluidra (AstralPool BlueFit / Riiot Wave): Fluidra is a global pool and wellness equipment manufacturer that owns AstralPool and acquired Riiot Labs (maker of the Wave smart pool analyzer). It competes with ONDILO across the broader pool equipment stack, with connected water monitoring as one component of a much larger portfolio.
