Built by engineers who trust evidence, not certificates.

In 2022, a widely-cited investigation found that a significant share of REDD+ forest protection credits issued under major voluntary standards did not represent the carbon reductions claimed. The problem was not fraud in the conventional sense — it was missing data linkage. Satellite canopy measurements existed, methodology audits existed, registry records existed. But no system connected them into a single machine-readable provenance trail. A credit's serial number proved issuance, not what was actually measured in the forest.

Nathan Osei had spent several years at a Minneapolis geospatial analytics firm building environmental data pipelines and leading measurement verification for a major North American forest carbon project. He had seen from the inside how the chain of evidence fragmented at each handoff — from field measurement to validator to registry to buyer. Priya Sundaram had built cryptographic data lineage and audit infrastructure at a fintech company, the same engineering pattern applied to financial settlement trails. When they began working together in late 2022, the fit was direct: carbon credit provenance needed exactly the chain-linking architecture that financial markets use for settlement integrity.

Co2Pathio was incorporated in Minneapolis in early 2023. The first registry integration pilot was completed that same year. As of 2025, Co2Pathio-traced credits span three voluntary registry standards and seventeen project types — with eight registry integrations active.
