Droughts, floods, pressure on resources: hydrological data has become strategic. VorteX-io, founded in Toulouse in 2019, positioned itself on this market early on. With 8.5 million euros raised in May 2026, the startup is taking a decisive step towards its international ambitions.
Analysis by the experts at Auris Finance, advisors in mergers, acquisitions and financial engineering.
VorteX-io has announced a Series A round of 8.5 million euros, led by Seventure Partners‘ Blue Forward Fund, alongside Banque des Territoires and Daphni through its Time4 fund. Two years after an initial round of 2.9 million euros, the company now operates close to 1,000 stations across four continents and collected more than 4 million data points in real time in 2025.
The company is targeting revenue of 10 million euros by 2027, up from 3.3 million in 2025. An ambitious growth trajectory, but consistent with the market’s momentum and the traction already shown with governments and public agencies.
Founders from the heart of French space research
VorteX-io was founded by Jean-Christophe Poisson and Guillaume Valladeau, two engineers who spent 15 years at CLS, a CNES subsidiary specialised in space oceanography. That background is not incidental: it explains why VorteX-io did not build just another measurement tool, but a systemic approach combining autonomous stations deployed in the field, an operational control centre and a data analytics platform.
Guillaume Valladeau, co-founder and chairman, sets out the strategic context: “Water has always been a global strategic sovereignty issue and a pillar of national resilience. Today, this challenge is intensifying and is calling for ever more precise management of the resource. You can only effectively protect and steer what you measure and know precisely: mastering the data, the infrastructure and the associated decision-making capabilities is therefore essential.“
A funding round that says more than the headline figure
The make-up of the investor syndicate accurately reflects the nature of the market VorteX-io is addressing. Seventure Partners, through its Blue Forward Fund dedicated to water impact solutions, brings strong sector credibility. Banque des Territoires, which is reinvesting after having already taken part in the 2024 round, sends a clear signal of confidence in the trajectory. Daphni, through Time4, rounds out the picture with an impact-driven approach.
Isabelle de Cremoux, chair of the management board at Seventure Partners, sums up the investors’ conviction: “Access to reliable, real-time data has become a strategic necessity, as climate change intensifies water-related risks across Europe.“
International ambitions rooted in sovereignty
The funds will be used to strengthen the company’s presence in the Balkans, North Africa and Asia (India, Laos, Cambodia, Vietnam), regions that are growing economically and industrially and where demand for sovereign hydrological solutions is on the rise.
Between 2023 and 2025, VorteX-io benefited from the support of the European Innovation Council to develop the first European river forecasting service. This institutional recognition, combined with Banque des Territoires’s presence on the cap table, positions VorteX-io as a leading player in the ecosystem of sovereign water management technologies, a segment that is drawing growing attention from governments and international organisations.
Jean-Christophe Poisson, co-founder and CEO, sums up the ambition: “This fundraising marks a decisive step: accelerating our roll-out in France and internationally, with governments, public agencies and the major international organisations committed to the sovereign management of water resources.“
