vorteX-io and the EIC Accelerator: 1,000 River Sensors Promised

vorteX-io, founded in Toulouse in 2019, makes solar-powered micro-stations, with hardware inspired by satellite technology, that measure river height, surface speed and temperature from bridges, feeding a real-time forecasting service for floods and droughts. It was selected in the EIC Accelerator's January 2023 cut-off and received an EU grant of €2.50 million for WHYLD, a €3.67 million project that ran from June 2023 to June 2025, according to CORDIS. The plan was to install 1,000 micro-stations in France and Croatia by the end of 2024 and 2,000 more across Europe by 2026, the company said in June 2024.

The project is closed. Its final report lists three results in total: "Advancements in River Flow feature", "Advancements in GNSS-signal-derived Rainfall estimation" and "Improvements in User interface of Software", according to the CORDIS reporting page. It gives no station count. In June 2024 the company planned to equip more than 200 sites in France and almost 300 in Croatia by the end of that summer, according to its progress update, but it has not published how many were actually installed. Its website now says 342 watersheds are equipped with its stations.

Where vorteX-io Stands Now

The company is active and sells monitoring to local authorities, companies, insurers and space agencies checking satellite measurements. French company register data list a net profit of €101,528 for 2024, with the revenue field recorded as zero, according to recherche-entreprises. The company filed its latest accounts in May 2026, BODACC notices show. It has not said whether the planned 2,000 additional European stations are being installed.

The Technology: Satellite Methods on a Bridge

Each micro-station is self-powered by solar panel, sends data over mobile networks and is fixed out of reach of floods and vandals, in some cases by rope-access technicians on bridges, the company says. The WHYLD project also worked on estimating river flow and rainfall from GNSS satellite signals. The company works with the World Meteorological Organization's Associated Programme on Flood Management.

What the EIC Award Promised, and What the Record Shows

The award promised a large-scale real-time hydrological database, starting with 1,000 stations in two pilot countries. The company has published plans and site preparation, not an installed total. The final report does not say whether the rest were installed, does not name customers and does not quantify the forecasting service.

The Money

In May 2024 vorteX-io raised €2.9 million led by Banque des Territoires and MAIF Impact, with AFI Ventures, SpaceFounders France and bank financing, according to Silicon Canals. The final report states this was partly to meet the 30% co-financing the EIC grant requires, and that the money paid for "1000 new v2.1 micro-stations", staff and research.

What Cannot Be Checked

Why Europe Should Care

The final report cites climate-driven floods as the reason for WHYLD, and Croatia's national water agency joined the rollout. Real-time river data is a public good for flood warning. The public record does not show how much of the network the EU paid for has been built.
