Bluenumber (B#) is a technology company building ethical, data-driven platforms for traceability, transparency, and accountability. We enable businesses to
verify supply chain claims and comply with human rights, ESG, and sustainability regulations—while respecting the data rights of workers and producers.
B# operates across global supply chains, with deployments in agriculture, electronics, and manufacturing. We are active in countries like Malaysia, India,
China, Australia, and the UK, supporting clients and data creators with tools that turn fragmented insight into verified action.
We partner with brands, buyers, certification schemes, industry platforms, and responsible sourcing teams. Our users include sustainability leaders, procurement managers,
legal advisors, and audit teams seeking credible, real-time insight from the people who matter most: those at the bottom of the supply chain.
B# was born out of a challenge: how can companies prove their commitments to human rights and sustainability, not just state them? The answer started with people—especially those whose labor, land, or data fuels global systems.
We built platforms that respect their voice, license their data, and give companies the verified insights they need. Today, B# is a leader in worker- and farmer-centered traceability tech.

Individuals see data assets in their Personal Data Vault (PDV), activate their SSI Wallet to receive credentials, shows who they exchanged data with.

Organisations manage their data vault, SSI wallet and functions to connect, deploy ODK surveys and credential B# holders with consent
A person creates their own B#SSI with their mobile number and receives OTP credentials for any service or app in the B# Ecosystem. They own all data they create
B# App and BlueSky™ are reciprocal services for people and organisations to operate ethically with each other in the B# Ecosystem.

CIMMYT uses Bluenumber’s technology to enable data repatriation, granting farmers ownership and control over their farm-related data. With this ownership, farmers can participate in the BCX data market, where they have the opportunity to connect directly with companies interested in purchasing their data, thereby increasing their potential for data-driven revenue. This approach empowers farmers by ensuring they benefit economically from the responsible use of their data, while organisations gain access to valuable, authenticated information for research, traceability, and sustainable sourcing.
Sourcery leverages Bluenumber’s advanced data governance technology to empower farmers with full ownership and control over their agricultural data. Through this system, farmers can securely trade their organised data with relevant organisations, generating income each time their data is accessed or purchased. This approach ensures that farmers remain the primary beneficiaries of their data, while organisations receive high-quality, consent-based information that supports transparency and value creation across the agricultural sector. By prioritising farmer consent, privacy, and economic incentives, Sourcery and Bluenumber are setting a new standard for ethical data sharing and sustainable rural development.
