Thallo

What Thallo does

Thallo is a London-based carbon marketplace infrastructure provider founded in 2019 (operating since) and incorporated as Thallo Limited in 2021 in England and Wales (company number 13578541, registered office in Basildon). The company operates a two-sided platform connecting carbon credit project developers with corporate buyers, supplemented by an Enterprise API for embedded point-of-sale carbon integration. Its core differentiator is a world-first two-way blockchain bridge enabling tokenized carbon credits to move between major registries (Puro.Earth, Gold Standard, Biocarbon Registry, Socialcarbon) and blockchain networks (Celo, Polygon, Chainlink, Filecoin), producing tamper-proof audit trails for retirement and disclosure.

The product surface spans the Marketplace (self-serve buyer/seller platform with no supply-side listing fees), Marketplace Pro (premium tier with co-branded certificates, dedicated customer success, buy-and-hold), Procurement Manager (order/invoicing/retirement tracking), and Carbon Dashboard (harmonized carbon and financial data). The Enterprise API enables fintech, e-commerce, and consultancy partners to embed carbon purchasing directly into their user journeys. Sustainability Services, launched as an add-on, provides fractional sustainability team support (ESOS, SECR, Scope 1-3) for UK companies on tiered subscriptions starting at £1,500/month.

Thallo monetizes through demand-side transaction fees, API access subscriptions, Marketplace Pro premium tier fees, and Sustainability Services subscriptions. The company has raised $2.5M in seed funding (November 2022) from Allegory Labs, Arcan Capital, Cerulean Ventures, Flori Ventures, Friendly Trading 2, Ripple, and Climate Collective, and serves a diversified customer base including Yamo, Zumo, Chemion, zeroCO2, Sustainable Travel, Reewild, CarbonBit, Nupico, and Off London. The company employs 11-50 people and reports strategic alliances with SCB and IETA membership.

Core offering

Thallo operates a carbon credit marketplace platform that connects project developers (sellers) with companies and consultancies (buyers) seeking to offset emissions. The platform offers direct access to verified credits from registries such as Gold Standard, Verra VCS, Puro.Earth, and Biocarbon Registry, supported by blockchain-based audit trails and a two-way bridge for tokenized carbon credits. An Enterprise API enables partners to embed carbon offsetting into their own platforms, and a separate Sustainability Services line delivers fractional sustainability team support to UK companies.

Product overview

The core platform consists of the Marketplace for direct carbon credit transactions, with three add-on modules: Marketplace Pro (enhanced features with co-branding and customer success support), Procurement Manager (order management and invoicing), and Carbon Dashboard (data tracking and analytics).

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Sylvera: Independent carbon credit ratings provider using satellite and ML to assess project quality. Adjacent to Thallo as a quality/data layer in the VCM stack rather than a marketplace, but serves the same enterprise buyers.

Direct peers

• Cloverly: Carbon offsetting API platform providing verified credits and integration into enterprise workflows. Closely comparable to Thallo on API-first architecture, registry integrations, and embedded carbon use cases.
• Pachama: Marketplace for nature-based carbon credits combining satellite verification with project developer sourcing. Overlaps with Thallo's marketplace and registry-agnostic verified credit proposition.
• Patch: Developer-first carbon offsetting API used by brands to embed offsets at checkout. Directly comparable to Thallo's Enterprise API for embedded point-of-sale carbon purchases and shares fintech and e-commerce customers.
• KlimaDAO: Decentralized autonomous organization building on-chain liquidity for tokenized carbon credits. Directly comparable to Thallo on the tokenized carbon infrastructure thesis but takes a DeFi-native rather than registry-bridged approach.
• AirCarbon Exchange: Global carbon credit exchange for trading spot and futures on tokenized voluntary offsets. Comparable exchange-style marketplace and tokenization infrastructure play in the same VCM.
• CarbonX: Carbon credit marketplace and infrastructure platform enabling enterprise procurement. Directly comparable to Thallo on marketplace + procurement + API offering for corporate buyers.

Broad incumbents

• Gold Standard: Leading carbon credit registry with high-integrity certification standards and a Thallo integration partner. Incumbent at the issuance layer that could vertically integrate into digital distribution.
• Puro.earth: Carbon removal registry (biochar, geological storage) and Thallo partner with live two-way bridge integration. Functions as both a partner and a registry incumbent capable of disintermediating marketplace layers.
• Verra: Largest global carbon credit registry (VCS program) and a Thallo integration partner. Broader incumbent in the registry/issuance layer that could compete by internalizing tokenization infrastructure.
