Our expertise

The company benefits from Christian Dumard’s 35 years of extensive experience in routing the world’s best racing boats, combined with Basile Rochut‘s expertise in decision science and AI. 

This is how MWI aims to become the trusted marine weather reference for safety, sustainability and support.

Christian Dumard

CEO

His work has supported some of the world’s most demanding ocean races and high-risk marine projects, shaping MWI’s approach to precision, uncertainty management, and decision responsibility.

Basile Rochut

CTO

Expert in decision science and AI, independent router. Basile focuses on translating complex weather and performance data into operational decision-support tools, bridging scientific research and real-world maritime use.

why we exist

Maritime operations are facing pressing challenges such as growing weather uncertainty linked to climate variability, fuel consumption and emissions reduction targets, tighter safety and compliance requirements, limited formal training in meteorology, despite full responsibility placed on decision-makers.

Our Mission

MWI transforms complex and uncertain weather data into clear, structured decision support, allowing mariners to act with confidence without requiring meteorological expertise.

Our Purpose

We exist to encourage a fairer use of the sea, improve safety at sea and support maritime decarbonisation by sharing trusted marine weather expertise.

Our Vision

We aim to become a trusted marine weather reference for safety, sustainability and support.

our approach

MWI solutions are built on a single core technology, shared across all applications and adapted to different maritime contexts.

Human expertise at the centre

Weather intelligence is always contextualised and validated by marine weather specialists, ensuring that outputs remain meaningful, defensible, and actionable.

Maritime-environment

Operational reality first

Our routing and performance models reflect actual vessel behaviour at sea, not theoretical assumptions.
They evolve with changing conditions, constraints, and operational feedback.

Science, enhanced by AI

We use AI-driven data processing across the platform to qualify weather models, assess uncertainty, and structure large volumes of information.
AI is used to support analysis, not replace judgement.

our values

Humanity

Uncertainty is inherent to weather. Recognising and managing it is central to our approach. We provide useful advice whenever needed, with care and empathy.

Reliability

Decisions at sea require consistent, well-founded support. We acknowledge complexity and uncertainty, and work to make information understandable and usable.

Excellence

We acknowledge complexity and uncertainty, and work to make information understandable and usable.
