Seafields, the world’s first Sargassum seaweed management and farming company, has launched its second crowdfunding campaign on Crowdcube – giving angel investors and the general public the chance to back a scalable solution that can transform an ecological crisis into a profitable, planet-positive industry. At full deployment, Seafields’ model could remove up to 42 gigatonnes of CO₂ from the atmosphere while opening a multi-billion-dollar market for sustainable bio-feedstocks.
The campaign is already building strong momentum, with over £167,370 raised already in this round from more than 140 investors as of 11 August, contributing to secured total funding of equity, debt and grants of £2.9 million as of 31st March 2025. Seafields is offering shares at £6.04 via Crowdcube, with the campaign due to close on 5 September 2025.
Every year, millions of tonnes of Sargassum seaweed inundate coastlines across the entire Caribbean region, choking ecosystems, devastating tourism, and harming fishing industries. Seafields is transforming this environmental disaster into a high-value climate solution. As the only company worldwide capable of intercepting, managing, and cultivating Sargassum at scale, Seafields can provide a sustainable, year-round supply for emerging bio-based industries—without supply chain risk—while generating permanent carbon removal credits.
Through uniquely developed barriers and paddocks, Seafields’ SeaClear platform intercepts Sargassum before it reaches shore, and stores it in water in their proprietary Algaeponix paddocks. This allows it to be kept fresh before being processed into industrial feedstocks for products including sustainable packaging, skincare, bioplastics, and biochar. Seafields’ SeaGrow farms have significant production capacity, for example, a 60-paddock farm over 10 years produces 482,591 litres of biostimulant annually. Through a combination of operating their own farms and licensing, Seafields will create over 100 farms in the Caribbean region, solving the Sargassum issue in the central Atlantic.
Seafields’ platforms have already fostered partnerships worth over $2 million. The company is currently working with Caribbean resorts on SeaClear farm opportunities, and is signing their first offtake agreements for Sargassum derived products such as biostimulants. Recently, Seafields signed a Letter of Intent (LOI) with Seedsman, a leading international cannabis seed bank, to supply a natural plant growth enhancer derived from sustainably sourced Sargassum. SeaClear is now being deployed in partnership with the island of St. Vincent through a pilot project with PRGD (Private Refuse and Garbage Disposal), supported by the OECS (Organisation of Eastern Caribbean States) UBEC (Unleashing the Blue Economy in the Caribbean) initiative, with funding from the World Bank.
SeaClear and SeaGrow are a clear signal of the growing commercial demand for ocean-derived products and Seafields’ ability to deliver sustainable, high-value feedstocks for the booming bio-based economy.
“SeaClear is going to completely change the game for Sargassum product companies,” says John Auckland, CEO of Seafields. “It’s completely unique in the seaweed world. As far as we know we are the only seaweed farming business from any seaweed species that can take a problematic seaweed bloom and preserve its freshness year-round in our unique Algaeponix paddocks.
This is so important because circular product manufacturers typically want a strong narrative around where they’ve acquired their feedstock, to justify the green premium they charge their customers. Additionally they want their operational emissions across their supply chain to be as low as possible.
SeaClear is entirely unique in being able to provide our customers with both of these benefits, that’s why many big names are reaching out to work with us. Together, we can turn a seaweed crisis into a climate-saving industry.”
The second Crowdcube raise is now live here. Investors will gain exclusive early access, rewards, and a chance to be part of the world’s first scalable Sargassum farming enterprise designed for planetary impact.
