Xpansiv Data Systems Inc.

Xpansiv Data Systems was founded in 2016 to build market infrastructure for environmental commodities. CEO John Melby, alongside co-founder Tim Reilly, designed the platform to bring transparency and liquidity to carbon and renewable energy certificate markets. The firm's wealth origin is corporate and venture-backed, not tied to a single family. The firm operates across three core asset classes: carbon credits, renewable energy certificates (RECs), and low-carbon fuel credits. Xpansiv's platform handles issuance, trading, and retirement of digital environmental assets via its CBL exchange and APX registry. The firm serves a global client base across North America, Europe, and Australia. Known partners include Shell and Delta Air Lines, which have used the platform for carbon offset procurement (per public record, 2023). Xpansiv employs over 200 professionals across offices in New York, San Francisco, Spokane, and Sydney. In May 2024, the firm announced a partnership with the International Air Transport Association to digitize aviation carbon credit trading (per public record, May 2024). The firm has raised over $200 million in venture funding from investors including S&P Global and BP Ventures. Xpansiv's structural differentiator is its dual role as both registry and exchange — a combination rare in the environmental commodity sector. By managing the lifecycle of credits from issuance to retirement on a single platform, Xpansiv reduces fraud and double-counting risks that have historically plagued carbon markets. This infrastructure-first model positions it as the primary settlement layer for voluntary carbon markets.
