What Kelp Blue does
Kelp Blue Biotech B.V. is a privately held marine agriculture company founded in 2020 and headquartered in Zeist, the Netherlands, with primary cultivation and processing operations in Lüderitz, Namibia and pilot farms in Alaska and New Zealand. The company cultivates Giant Kelp (Macrocystis pyrifera) on large-scale offshore underwater structures anchored at approximately 15 metres depth and harvests the canopy to produce biostimulant ingredients for downstream use.
Its commercial product is StimBlue+, a biostimulant made from 100% cultivated Giant Kelp and processed using a patented cell-wall bursting method intended to maximize bioavailability of bioactive compounds. The company supports the formulation with an annually recurring field trial program (approximately $500,000 invested with accredited third-party research organizations, 90+ Good Experimental Practice trials completed) that has produced quantified yield and quality improvements across more than a dozen crop types. Regulatory assets include CE registration enabling EU-wide marketing, ISO 9001 certification of production and sales processes, and compliance with EU and NOP organic farming standards.
Kelp Blue makes money by selling StimBlue+ directly to commercial farmers and through distributors (notably Royal Houweling in Europe and North America), with agronomist-supported quote-based pricing for commercial customers and publicly listed €4.50 pricing for the Home & Garden consumer variant. A future revenue stream is being developed via a Gold Standard carbon credit methodology co-developed with the Kelp Forest Foundation, expected after 2026. The company's stated 2029 vision targets 70,000 hectares of kelp farms, over 1 million tons of CO₂ removal annually, and 400+ direct plus 800-1,000 indirect jobs.
