Revenue model
- Sargassum Management Fees: Primary near-term revenue stream from intercepting Sargassum at sea and managing it for Caribbean hotels and governments. Over the next two years, Seafields anticipates the majority of revenue will come from Sargassum management fees.
- Biomass Sales (Dried Pulp): Supplying dried Sargassum pulp to biorefineries for green products. Any unsold pulp is converted into biochar. Seafields provides Sargassum biomass as a feedstock for manufacturers with traceable supply chains.
- Biostimulant Licensing: Processing fresh Sargassum into natural biostimulants under license from Carbonwave. Revenue share opportunities with partners for biostimulant products.
- Biochar and Carbon Credits: Converting unsold or waste Sargassum pulp into biochar through partners like RubisCO2 and MacroCarbon. Biochar carbon credits have established methodologies and can go to market immediately. Carbon credits anticipated to remain less than 10% of revenue.
- Refined Polysaccharides: Revenue share opportunities from partners producing refined alginates, fucoidans and other polysaccharides from Sargassum biomass.

Seafields Solutions product offering
Product offeringCore offering
Seafields Solutions intercepts pelagic Sargassum seaweed blooms at sea before they reach shorelines, holds the biomass in proprietary AlgaePonix Smart Paddocks to preserve freshness, and processes it into downstream products including biostimulants, dried pulp, biochar, and verified carbon credits. The company's SeaClear and SeaGrow solutions extend the offering into nearshore aquafarming and shore-based seaweed cultivation for Caribbean hospitality, government, and bio-based product customers.
Product overview
Seafields operates a multi-product portfolio centered on transforming problematic Sargassum seaweed blooms into sustainable resources through the circular economy. The core offering consists of SeaClear and SeaGrow nearshore moored aquafarm systems that intercept Sargassum before it reaches coastlines. Caught seaweed is stored year-round in proprietary AlgaePonix smart paddocks and then processed into multiple value streams: biostimulants for agriculture (under Carbonwave license), dried pulp for biorefineries producing bioplastics and biofuels, and biochar for construction materials and carbon sequestration. The company also generates carbon credits from biochar production. This integrated approach provides coastal protection services while supplying sustainable feedstock to manufacturers.

Seafields Solutions competitors and assessment
Company assessmentDirect peers
- Kelp Blue: Large-scale kelp farming company producing biostimulants, textiles, and food. Comparable in applying offshore aquaculture to produce multiple downstream bioeconomy products, with similar verticalization strategy.
- Running Tide: US-based ocean CDR company that grows and sinks kelp for carbon removal. Closest analog in business model (seaweed farming + ocean-based CDR) even though species and geography differ — both target voluntary carbon markets at gigatonne scale.
- RubisCO2: Biochar production partner of Seafields that converts Sargassum pulp into biochar for agriculture and carbon sequestration. Direct overlap in biochar processing technology and customer base.
- Origin by Ocean: Finnish company developing seaweed-based bioplastics and bio-based ingredients. Seafields explicitly lists Origin by Ocean as a partner and competes in the same seaweed-to-bioplastics feedstock space, with overlapping downstream product markets.
- Carbonwave: Carbonwave is the largest processor of Sargassum, producing biostimulants (Sarga Agriscience), cosmetics emulsifiers, and vegan leathers. It is both a direct competitor for Sargassum biomass and Seafields' upstream partner/licensor for biostimulant processing — making it the single most comparable peer in the Sargassum value chain.
- MacroCarbon: Seaweed-to-biochar company led by Dr. Mar Fernández-Méndez (who is also a Seafields Scientific Advisor). Operates at the same intersection of seaweed biomass and biochar carbon credits, and shares R&D leadership with Seafields.
Emerging players
- AlgiKnit: Materials company producing kelp-based textile fibers. Comparable downstream market (sustainable materials) sourced from cultivated seaweed, though different end-product focus.
- Phykos: Seaweed biotech startup focused on algae-derived biostimulants and biopolymers. Overlaps with Seafields in seaweed-to-biostimulant product strategy but at earlier stage and different species.
- Coral Vita: Caribbean-based marine restoration company using aquaculture-adjacent techniques to grow coral for reef restoration. Overlaps in Caribbean operating geography, marine biology expertise, and B2G/B2B sales motion to coastal stakeholders.
- PlanBlue: Ocean monitoring/seafloor mapping startup using satellite and in-situ sensing. Adjacent technology overlap with Seafields' sensing-equipped AlgaePonix paddocks and digital-twin optimization layer.
