What Supercritical does

Supercritical (legal entity: Supercritical Tech Ltd.) is a London-based B2B carbon removal marketplace founded in 2021 by Michelle You (CEO) and Aaron Randall (CTO), the team that previously built Songkick to 20M monthly users before its Warner Music Group acquisition. The company operates a two-sided marketplace that connects 200+ corporate buyers with vetted permanent carbon dioxide removal (CDR) supply across eight methods — biochar, BECCS, enhanced weathering, direct air capture, DAC with ocean storage, woody biomass sinking, bio-oil, and mineralization — tracking 600+ suppliers that represent 80% of the global durable CDR market. Underpinning the platform is a proprietary 118-point hierarchical vetting protocol that scores projects across climate science, environmental factors, social impact, and delivery risk, rejecting 84–88% of assessed projects and enforcing a quality bar that drives a documented 4:1 sales premium for vetted credits versus lower-quality supply.

The core product is the Supercritical Marketplace (platform.gosupercritical.com), a self-serve buyer interface providing live pricing, availability, and quality data, supported by a three-layer delivery protection system (buffer pool credits, pre-vetted pathway alternatives, and delivery-tolerant contracts). A Supply Development Program co-develops new CDR projects from engineering design through megatonne offtakes, often originating supply that would not otherwise reach market. Named buyers include Microsoft, Google, Stripe, Shopify, Boeing, Virgin Atlantic, Airbus, JP Morgan, Amazon, Frontier, Rothschild and Co, XTX Markets, and Tide, with diversified procurement patterns across technology, aviation, financial services, and retail verticals.

The business model combines marketplace credit sales (Supercritical takes a margin reselling per-tonne credits at prices ranging from $162/t for biochar to $812/t for DAC with ocean storage) with 5–10 year multi-year offtake programs that lock in supply ahead of the 2028 SBTi Corporate Net-Zero Standard V2.0 mandatory CDR procurement date and 2029 UK ETS CDR integration. Pricing is public on a per-tonne basis. The company has raised $13M in Series A funding from Lightspeed Venture Partners (2023) and secured a follow-on round led by Greencode Ventures (May 2026) with participation from existing investors. Carbon-negative buyer coalitions such as Frontier transact through the platform, and the climate science team — led by Dr Mai Bui, an SBTi advisor and Puro.earth scientific advisory board member — is integrated with UK DESNZ/BSI on CDR framework development.

Revenue model

1. Marketplace credit sales (transaction commission): Core revenue stream: Supercritical acts as marketplace intermediary, sourcing permanent CDR credits from vetted suppliers and selling them to corporate buyers. Pricing is per-tonne (e.g., biochar from $162/t, DAC with ocean storage from $812/t), with Supercritical taking a margin on each transaction. Mix includes spot credit purchases and longer-term offtakes.
2. Multi-year offtake structuring and delivery management: 5–10 year procurement programs designed around buyer decarbonization strategy. Includes annual portfolio reviews, quarterly delivery monitoring, risk flagging, buffer pool protection, and dedicated account teams. Recurring, contract-based revenue over multi-year horizons.
3. Supply development and project commercialization services: Capital and services deployed to develop early-stage CDR projects from engineering design through commercial offtake. Supercritical commits demand upfront to unlock project financing, earning returns through eventual credit supply and distribution rights.

Core offering

Supercritical operates a two-sided B2B marketplace for permanent carbon removal (CDR) credits, connecting vetted project developers and suppliers with corporate buyers. The company sources, co-develops, and distributes permanent CDR credits across eight methods (biochar, BECCS, enhanced weathering, DAC, DAC with ocean storage, woody biomass sinking, bio-oil, mineralization) under a 118-point scientific vetting protocol that rejects ~88% of assessed projects. Beyond spot and multi-year offtake transactions, it runs a Supply Development Program that co-creates early-stage CDR projects and offers a three-layer delivery protection system for buyers.

Product overview

Supercritical operates a unified carbon removal marketplace platform that sources, creates, and guarantees permanent supply of carbon dioxide removal credits for the world's most demanding corporate buyers. The core Supercritical Marketplace is built around seven distinct removal method modules—Biochar (from $162/t), BECCS (from $350/t), Enhanced Weathering (from $312/t), Direct Air Capture (from $618/t), DAC with Ocean Storage (from $812/t), Woody Biomass Sinking (from $375/t), and Bio-oil (from $750/t)—each priced and vetted independently but transactable in a single marketplace. Surrounding the marketplace are dedicated For Buyers procurement services (spot credits, multi-year offtakes, criteria-first portfolio design with three layers of delivery protection) and For Suppliers supply development services that co-develop new projects with early-stage producers. Underpinning every transaction is the 118-Point Vetting Protocol, Supercritical's proprietary due diligence framework that scores projects across climate science, environmental factors, social impact, and delivery risk, rejecting 88% of assessed projects.

Direct peers

• Patch: Patch operates a B2B carbon credit marketplace that connects businesses with carbon offset and removal project developers via APIs and a self-serve platform. Closest direct competitor to Supercritical's buyer-procurement model, serving many of the same enterprise customer profiles and offering comparable spot credit and forward offtake structures.
• Watershed: Watershed is an enterprise climate platform combining carbon accounting, MRV, and procurement of high-quality credits including engineered removals. Comparable to Supercritical on the procurement side (buying and structuring offtakes on behalf of large corporates) but broader in scope, bundling software and services.
• Rubicon Carbon: Rubicon Carbon is a carbon credit marketplace and developer platform offering diversified portfolio solutions across nature-based and engineered removal credits to corporate buyers. Directly comparable marketplace model and customer segments to Supercritical, with a heavier emphasis on portfolio construction and risk management.
• Cloverly: Cloverly provides an API-based carbon credit marketplace enabling businesses to integrate carbon calculations and high-quality offset purchases into their products and operations. Comparable marketplace and tech-integration approach, overlapping in tech and fintech buyer segments though lighter on durable CDR.
• cdr.fyi: cdr.fyi is a public marketplace data platform and procurement channel for durable carbon removal, tracking CDR purchases, prices, and project performance across suppliers. Directly comparable as the leading CDR-specific marketplace data and procurement layer, and a key distribution channel for many of the same suppliers Supercritical works with.
• South Pole: South Pole is one of the largest global carbon credit and climate solutions providers, offering project development, advisory, and procurement across avoidance and removal credits. Comparable buyer-side proposition and global enterprise customer base to Supercritical, with a much broader scope including avoidance credits and advisory services.

Emerging players

• Sylvera: Sylvera provides independent ratings and analytics on carbon credit quality and project performance across registries and project types. Adjacent and partially overlapping with Supercritical's vetting mission; not a marketplace itself but increasingly integrated into enterprise procurement workflows that also feed into Supercritical's funnel.
• NCX: NCX is a nature-based carbon credit marketplace that helps landowners generate and sell forestry and improved forest management credits to corporate buyers. Comparable two-sided marketplace model with overlap on procurement-style customer relationships, but focused on nature-based rather than engineered removal pathways.

Broad incumbents

• Isometric: Isometric is a CDR certification registry and standard-setter whose methodologies (including the Distributed Biochar Module v1.1 used by the Varaha partnership) underpin many of the credits Supercritical distributes. Functions as an upstream infrastructure provider rather than a direct competitor, but its certification choices materially shape which supply can flow through the Supercritical marketplace.
• Puro.earth: Puro.earth is a leading CDR registry and standard (biochar, BECCS, DAC) whose certified credits are sold through multiple channels including Supercritical's marketplace. Not a direct competitor; functions as the upstream certification layer that enables Supercritical's supply, and where Director of Climate Science Dr Mai Bui holds an SAB seat.
