Not many global organizations can trace their origin back to a modest vegetable garden in rural Nova Scotia, but that’s where our story begins. Among the rows of lush green plants, our Founder Louis Deveau first fell in love with seaweed.
As he watched his father gather seaweed from the rocky shoreline of La Baie St. Marie and spread the nourishing algae over the garden’s soil, Louis was mesmerized by its almost magical growing power. The ground where his father applied seaweed sprung forth with plants that were healthier and more productive.
What began with one observation about nature’s remarkable ability to help plants thrive has grown into a global innovation company dedicated to translating natural biology into practical solutions for plants, animals and people.

As Acadian Seaplants continues to evolve, so too does our leadership – ensuring continuity of purpose while positioning the company for long-term growth and impact. Building on the strong foundation established over decades, Jean‑Paul Deveau, son of founder Louis Deveau, has assumed the role of Executive Chairman, providing strategic oversight rooted in deep knowledge of the company’s heritage and values. At the same time, Nelson Gibson, former President of Acadian Plant Health, now serves as CEO of Acadian Seaplants, bringing a proven track record of science-led innovation, global leadership, and performance-driven growth. Supporting this next phase, James Maude has been appointed Chief Operating Officer, strengthening operational excellence across the organization. Together, this leadership team reflects a thoughtful evolution — one that honors Acadian’s legacy while confidently guiding the company into its future as a global leader in seaweed science and sustainable solutions.
