Marine Weather Intelligence (MWI)

What Marine Weather Intelligence (MWI) does

Marine Weather Intelligence (MWI) is a French deeptech SaaS company founded in 2023 in Auray, France, by CEO Christian Dumard — a meteorologist with 30+ years of ocean racing experience spanning three Vendée Globe campaigns — and CTO Basile Rochut, an AI specialist. The company delivers AI-driven marine weather routing and probabilistic forecasting through a platform that aggregates 50 to 100+ ensemble weather models, applies proprietary AI-driven bias correction, and produces exceedance probability forecasts calibrated to vessel-specific thresholds. The product is organized into four vertical solutions — MWI Offshore Energies, MWI Towage & Heavy Transport, MWI Shipping, and MWI Yachts — each backed by 24/7 AI monitoring and on-demand human expert support, with HSE-traceable Go/No-Go documentation for compliance and insurance workflows. Distribution is sales-led and enterprise-focused, with customers including Seaway7, Eiffage, Perenco, SAL Heavy Lift, Chantiers de l'Atlantique, Holland Shipyards Group, and Dixstone across offshore energy, heavy transport, commercial shipping, and yachting.

Revenue is generated primarily through annual SaaS subscriptions with custom enterprise pricing (no public tiers), supplemented by one-off service engagements and framework/master service agreements. The company is funded through an Ifremer Octo'pousse 2023 grant (€250,000, accompanied by Ifremer taking a 10% equity stake) and the June 2026 Equity Challenge first prize (€100,000 from Business Angels 35). With ~15–18 employees currently, MWI is preparing a €3 million Series A to scale headcount to ~50 by 2027 and expand into Asia and North America for global 24/7 service coverage. Strategic partnerships include an ESA Kick-Start feasibility study on the HWZSea satellite-based early-warning concept, and the company served as official weather consultant for the Vendée Globe 2024.

Partnerships

Five partnerships are on record, tiered core and minor.

• European Space Agency (ESA)coreStrategic or Co-development Partner · 1 January 2024ESA Kick-Start feasibility study on HWZSea (Hazardous Weather Zones at Sea), a next-generation maritime early-warning concept designed to enhance operational safety in demanding offshore and shipping environments. The study assessed how space-based satellite data could strengthen short-term hazard anticipation. The collaboration provided access to high-quality satellite data streams and technical validation within a structured innovation framework. The feasibility study confirmed technical relevance and operational interest of the HWZSea concept.
• IfremercoreStrategic or Co-development Partner · 1 January 2023Following Marine Weather Intelligence's win of the Octo'pousse 2023 innovation competition, Ifremer (French national research institute for ocean science) took a 10% equity stake in the company. The partnership includes collaboration on a breakthrough in wave height forecasting and the development of a model qualification framework. Special contributions from Ghislain Lizée, Michaël Accensi, and Nicolas Maillard of Ifremer were essential to the wave height forecasting achievement. The relationship combines MWI's commercial routing expertise with Ifremer's scientific research capabilities.

• Bureau Veritas Marine & Offshore: Global classification society and marine services provider with weather routing and voyage optimization offerings. Overlaps with MWI on compliance-grade Go/No-Go decisioning and is a major counterparty to many of the same customers.

Direct peers

• StormGeo: Norwegian-headquartered marine weather routing and fleet decision support provider, now part of Alfa Laval. Directly competes with MWI across shipping, offshore, and towage segments with a much larger installed base and enterprise sales footprint.
• PredictWind: New Zealand-based weather routing specialist focused on yachts, sailing, and smaller commercial vessels. Competitor to MWI Yachts with comparable web/app self-serve routing interface and forecasting depth.
• Applied Weather Technology (AWT): US-based marine weather routing and voyage optimization platform serving commercial shipping fleets. Closely comparable offering to MWI Shipping, with established Bunker and Bonvoyage optimization products.
• Tidetech: Australia-based commercial marine weather and ocean current data provider serving shipping, offshore, and yacht racing. Comparable to MWI on routing accuracy and oceanographic data integration, though smaller in scale.

Emerging players

• Spire Global: Satellite-powered weather and ocean data provider with growing maritime applications. Comparable to MWI's HWZSea direction, focused on radio occultation and GNSS-derived atmospheric data for routing-adjacent use cases.
• ClearSyS / PredictWind Marine (commercial arm): Emerging software-focused routing platforms targeting niche commercial shipping and offshore service segments. Comparable to MWI on AI-driven probabilistic routing and SaaS delivery, though with smaller scale.

Regional players
