Redex product offering
Product offeringCore offering
REDEX operates a one-stop digital ecosystem for Renewable Energy Certificates (RECs), providing a cloud-based SaaS platform that covers the full REC lifecycle — asset registration, verification, marketplace trading, and retirement. The platform (REHash) is the only system API-integrated with the I-REC(E) Registry and also supports APX TIGR and China GEC standards across more than 60 countries. Supplementary offerings include a supply chain decarbonisation platform (RESuite), a mobile app for small-scale solar asset registration (REConnect), and a B2B API suite (REAPI) for embedding REC functionality into third-party sustainability software.
Product overview
REDEX operates a one-stop ecosystem for Renewable Energy Certificates (RECs), built around four interconnected digital solutions. REHash is the core trading platform integrated with the IREC Registry, enabling the full REC lifecycle from asset registration and certificate issuance through to marketplace trading and retirement. REConnect is a mobile app that enables small-scale solar asset owners to self-register their devices and monetise renewable energy generation. RESuite supports corporate buyers in tracking supply chain renewable energy usage and managing REC procurement. REAPI provides B2B integration capabilities via REST API. The four products share data and workflows across the ecosystem, covering both the voluntary I-REC(E) and APX TIGR markets as well as China's Green Electricity Certificate (GEC) market.

Redex competitors and assessment
Company assessmentBroad incumbents
- APX: APX operates the TIGR Registry spanning 40+ countries and 1,500+ renewable energy projects and is REDEX's official Asia partner. As the underlying registry infrastructure provider, APX is comparable as a REC platform incumbent but operates at the registry/standards layer rather than the value-added trading UI layer where REDEX competes.
- Verra: Operator of the Verified Carbon Standard and other major environmental standards/registries globally. Comparable as a registry operator in the environmental commodities space, though primarily carbon-focused rather than REC-focused; structurally similar model to TIGR/I-REC(E).
Others
- Evident: Evident is the Accredited Code Manager and Registry Operator for the I-REC(E) Product Code, supporting markets in 60+ countries and serving as REDEX's integration partner. Comparable as the underlying infrastructure enabling REDEX's I-REC(E) trading capability, but operates at the registry layer rather than as a competing trading platform.
Direct peers
- South Pole Group: Global carbon credit and REC solutions provider offering project development, advisory, and B2B trading platforms for corporate sustainability buyers. Directly comparable as a multi-regional B2B platform for corporate renewable energy procurement with broader carbon services overlay.
- Terrapass: Digital marketplace for RECs and carbon offsets with both enterprise and consumer offerings. Comparable to REHash as a digital-first REC trading model, though primarily serving North American buyers and not directly competing in REDEX's core Asia/LATAM geographies.
- ClimeCo: Environmental commodities company providing carbon credits, RECs, and other environmental products to corporate buyers via a trading platform. Directly comparable as a multi-commodity environmental trading platform serving enterprise sustainability procurement needs.
Regional players
- 3Degrees: Renewable energy certificate and PPA broker serving North American corporate buyers. Comparable as a REC trading intermediary with enterprise focus, but geographically concentrated in the US/Canada and not directly competing in Asia, LATAM, or the Middle East where REDEX operates.
Emerging players
- Patch: API-first carbon credit marketplace enabling software platforms to embed carbon credit purchasing into their applications. Comparable to REAPI in offering B2B API integration for environmental commodities, but focused on carbon credits rather than RECs and earlier in its enterprise traction.
- Watershed: Enterprise carbon accounting platform that includes REC procurement and supply chain emissions tracking capabilities. Comparable to RESuite in addressing Scope 2/3 decarbonization with a software-led approach for large enterprises, though focused primarily on the US market.
- Cloverly: API-based carbon offset and sustainability platform enabling B2B integration of environmental commodity purchasing. Comparable to REAPI/REHash as a digital marketplace for environmental commodities with B2B integration capabilities, though focused on carbon offsets rather than RECs and serving primarily US-based enterprise buyers.
