Cascadia Seaweed

What Cascadia Seaweed does

Cascadia Seaweed Corp. is a Canadian vertically integrated producer of cultivated kelp liquid biostimulants, founded in 2019 and headquartered in Sidney, British Columbia. The company grows Saccharina latissima and Macrocystis tenuifolia on marine farms operated under license within the traditional territories of five coastal First Nations (Tsawout, Ahousaht, Uchucklesaht, Tseshaht, Metlakatla), then harvests and processes the kelp using proprietary extraction technology designed to preserve bioactive compounds (amino acids, complex carbohydrates, and naturally occurring plant hormones such as auxins and cytokinins) while delivering lower alginate levels and lighter colour than conventional extracts. Cascadia markets three core liquid biostimulant brands — FieldKelp (registered across most US states including CDFA approval in California), Kelpivex and RegenaKelp (both registered by the CFIA for the Canadian market) — and sells them in 1000-litre IBC totes through an authorized agricultural distributor network in Canada and the US, with white-label and private-label programs available.

The company operates a secondary Cascadia Nature-based Solutions (CNbS) division that monetizes biodiversity monitoring, kelp restoration and value-chain consulting services through proprietary technology platforms including LookSea programmable underwater cameras, the OceanNexus AI-powered data dashboard, and the Green Gravel Production System for kelp restoration. CNbS targets First Nations, government agencies (e.g., National Research Council of Canada), conservation groups, and international development partners (Plan International Canada, Jane Goodall Institute of Canada for the COSME Kenya project funded by Global Affairs Canada). A third product line, Agrifeeds (dried seaweed-based livestock feed additives), remains in R&D. Cascadia's go-to-market combines a small in-house direct sales team (Director of Sales and Marketing, Canadian and US Sales Managers) with distributor partnerships and active presence at industry events including ISS25, World AgriTech Summit, and COP28.

Cascadia has raised over CAD$18 million from equity and non-dilutive sources since founding, with a Series A first close of CAD$4M (against a CAD$7M target) in November 2024 led by impact-oriented investors including WWF Impact, Vere Ventures, Potato Impact Partners, and VertueLab Climate Impact Fund. The company holds a B Corp certification (score 113.5 in 2025, up from 90.4 in 2022), is a registered Benefit Company in British Columbia, and counts approximately 25 employees. Its new Port Edward biorefinery near Prince Rupert, BC (grand opening May 14, 2026, fully operational summer 2026) is expected to materially scale processing capacity and unlock US export volumes via the Port of Prince Rupert.

Revenue model

1. Liquid Kelp Extract Biostimulants: Cascadia's primary revenue stream is the sale of liquid kelp extract biostimulants (FieldKelp, Kelpivex, RegenaKelp) to large-scale agricultural producers across North America. Products are sold in 1000-litre IBC totes through a distributor network and white-label programs. The company also sells dried seaweed extracts as ingredients blended into third-party formulations. FieldKelp is available in most US States, Kelpivex and RegenaKelp are registered in Canada by CFIA.
2. Nature-based Solutions Consulting Services: Cascadia's Nature-based Solutions (CNbS) division offers paid consulting and project development services in kelp restoration, biodiversity monitoring, engineering innovation, and equitable seaweed value chain development. Services target First Nations, non-profit organizations, government agencies, and international development partners (e.g., Plan International Canada for the COSME Kenya project funded by Global Affairs Canada).
3. Agrifeeds (Livestock Feed Additives): Cascadia is developing dried seaweed-based feed additives for livestock. Products are still in the research and development stage and not yet commercially available. The World Bank recognizes seaweed as a valuable feed component with balanced amino acid profile and rich mineral/vitamin content.

Core offering

Cascadia Seaweed cultivates Saccharina latissima and Macrocystis tenuifolia kelp on marine farms in partnership with coastal First Nations in British Columbia, then harvests and processes the kelp into 100% natural liquid kelp extract biostimulants (FieldKelp for US growers, Kelpivex and RegenaKelp for Canadian growers) that improve crop yields, nutrient use efficiency, and abiotic stress resilience for large-scale agricultural producers. The company also operates a Cascadia Nature-based Solutions (CNbS) division offering paid consulting, biodiversity monitoring, kelp restoration, and value chain development services using proprietary LookSea cameras and the OceanNexus AI platform.

Expansion highlights6 records

Others

• Plan International Canada (COSME Project): Plan International Canada is the lead implementer of the COSME Kenya project for which Cascadia provides seaweed value-chain consulting via its CNbS division. It is a strategic development partner rather than a competitor, but a relevant ecosystem participant given overlapping marine restoration and blue-economy agendas with Cascadia's Nature-based Solutions work.

Direct peers

• BioAtlantis: BioAtlantis develops and markets seaweed-derived biostimulants and crop stress-management products targeting similar yield, abiotic stress, and fertilizer-efficiency use cases as Cascadia's FieldKelp, Kelpivex, and RegenaKelp. It is a direct peer in the biostimulant category serving row crop, specialty crop, and greenhouse producers.
• Kelpak: Kelpak produces Ecklonia maxima-based kelp biostimulants marketed globally for yield, root development, and stress resilience. It is a direct peer to Cascadia's liquid kelp extracts, serving comparable row crop and specialty crop customers with a similar biostimulant mechanism of action.
• Ocean Harvest Technology: Ocean Harvest Technology develops and markets seaweed-based feed ingredients for animal nutrition, including dairy, swine, and aquaculture. It is a direct peer to Cascadia's Agrifeeds product line, addressing the same livestock-feed value proposition with seaweed-derived ingredients.
• Acadian Seaplants: Acadian Seaplants is the largest independent marine plant processing company globally and the dominant North American supplier of seaweed-based biostimulant and crop-input products. It is the most directly comparable competitor to Cascadia's cultivated kelp biostimulant business, although it primarily relies on wild-harvested Ascophyllum nodosum rather than cultivated kelp.

Emerging players

• Mara Seaweed: Mara Seaweed is a Scottish seaweed cultivation and consumer products company producing cultivated kelp-based food and wellness products. It is an emerging peer in cultivated kelp with overlapping cultivation, processing, and value-chain development activities to Cascadia's CNbS work, although focused on food rather than agricultural biostimulants.
• Atlantic Sea Farms: Atlantic Sea Farms is a US-based kelp aquaculture cooperative partnering with coastal fishermen to cultivate kelp for food applications. It is an emerging peer in cultivated kelp with comparable grower-network and processing models relevant to Cascadia's vertically integrated approach, though focused on food rather than agricultural biostimulants.
• Ocean Hugger Foods: Ocean Hugger Foods develops plant-based seafood alternatives using seaweed and other ocean-derived ingredients. It is a thematic peer in cultivated seaweed commercialization, relevant for adjacent market insights into kelp cultivation and processing economics comparable to Cascadia's platform.

Broad incumbents

• Seasol: Seasol is one of the longest-established seaweed biostimulant brands globally, marketing a broad portfolio of kelp-derived liquid extracts and soil conditioners to home gardeners, horticulture, and agriculture. It is a broad incumbent in the same biostimulant category as Cascadia, with much deeper consumer brand presence and distribution.
• Algea (FMC Corporation): Algea, owned by FMC Corporation, is a global supplier of seaweed-based biostimulant and specialty nutrition products for agriculture. It is a broad incumbent competing in the same biostimulant category as Cascadia, benefiting from FMC's deep global distribution and formulation capabilities.
