GREAT YELLOW LTD

What GREAT YELLOW LTD does

Great Yellow Limited is a UK-based nature finance advisory and infrastructure company founded in September 2023 and headquartered in London. The company operates a vertically integrated platform connecting three constituencies: Nature Recovery Projects (land managers, farmer clusters, and estates), Project Investors (institutional capital), and Outcome Buyers (corporations seeking nature outcomes). Through its proprietary Great Yellow OS platform and a strategic partnership with Swallowtail, the company manages a combined portfolio exceeding 300,000 hectares, including over 40% of Defra-supported Landscape Recovery projects in the UK. The Evenlode Landscape Recovery, a 3,200-hectare farmer-led project, represents the company's flagship engagement and unlocked over £100 million in public funding from Defra.

The company's core technology stack centers on the Great Yellow OS for end-to-end project and portfolio management, the open-source Landscape Recovery Ontology for semantic interoperability across ecology, finance, and geospatial data, and a licensed integration with Treeconomy's satellite-based digital monitoring, reporting, and verification (dMRV) technology providing 10m-resolution biomass data. The company is FCA-regulated as an Appointed Representative of Infinity Asset Management LLP (FRN 1002518), enabling direct participation in regulated investment activities. Additional capabilities include work with Isometric on soil carbon removal and partnerships with Rebalance Earth for institutional capital aggregation, with a stated target of mobilizing £1 billion into UK catchments within three years.

Great Yellow generates revenue across five streams: transaction fees on carbon credit brokerage (Woodland Carbon Code), Biodiversity Net Gain unit sales, advisory and management fees on blended finance structuring (targeting approximately 10% IRR for investors), recurring revenue from long-term natural flood management and water quality contracts with utilities and government bodies, and subscription-based technology licensing and data services. Pricing is custom enterprise and project-specific, with multi-year contract structures. Distribution is exclusively direct B2B, supported by thought leadership through content, podcasts, and industry events. The company has transacted in excess of £58 million cumulatively across natural capital revenue streams, though this figure reflects deal value rather than recognized revenue. As of March 2026, the team comprised approximately 40 people organized across Nature Projects, Capital, and Trade divisions, following a £4 million seed round in January 2026.

Emerging players

• Pachama: Forest carbon marketplace using satellite data and ML to verify nature-based carbon projects. Comparable technology-and-marketplace approach to nature-based carbon credit sourcing, though focused on voluntary international forestry rather than UK statutory markets.
• Sylvera: Carbon credit ratings and analytics provider for voluntary carbon markets. Comparable as quality-assurance and pricing infrastructure for nature-based carbon credits, an adjacent layer to Great Yellow's carbon trading revenue stream.
• NatureMetrics: UK nature-tech company providing eDNA biodiversity monitoring and nature data analytics. Comparable as an enabling data layer for nature market verification, intersecting with Great Yellow's MRV/ontology work but focused on biodiversity rather than project finance.

Broad incumbents

• Climate Asset Management: Joint venture between HSBC and Pollination investing in natural capital solutions at scale. Comparable as a large-scale natural capital investor and asset manager; broader incumbent that could disintermediate smaller platforms like Great Yellow on institutional mandates.
• Pollination Group: Global advisory and investment firm focused on climate change and natural capital. Comparable as a broader incumbent providing strategic advisory, capital raising and asset management services in nature-based solutions, overlapping with Great Yellow's blended finance structuring.

Direct peers

• Environment Bank: UK-based provider of statutory Biodiversity Net Gain units, habitat banking and nature recovery projects. Directly comparable to Great Yellow's BNG unit creation and trading business, serving developers and landowners under the same Environment Act 2021 regime.
• Habitat Bank (The Biodiversity Consultancy): UK-focused habitat banking and biodiversity offset provider helping developers meet BNG obligations. Comparable in BNG unit supply, mitigation hierarchy services and statutory nature market participation.
• Rebalance Earth: Natural capital asset manager building infrastructure-grade revenue frameworks for UK catchment-scale nature restoration. Directly comparable institutional-capital aggregation strategy; also an active partner/investor of Great Yellow, making it both competitor and channel.
• Wychwood Biodiversity: UK BNG unit supplier and habitat bank operating in the same statutory Biodiversity Net Gain market, supplying verified units to developers and competing for landowner project origination.
• Swallowtail: Norfolk-based farmer-led nature-based solutions consultancy spun out of the Wendling Beck Project (largest BNG supplier in England). Sister company and formal partner of Great Yellow; most directly comparable in landowner-led project design and stakeholder engagement for landscape recovery.
