Patch as Carbon Distribution Platform
Brennan Spellacy, CEO of Patch, on the API layer of the carbon stack
Patch matters because it turns scattered carbon suppliers into plug and play inventory inside other software products. Instead of every project developer hiring its own sales team, negotiating separate contracts, and explaining registry details buyer by buyer, Patch standardizes listings, wraps supplier agreements around them, and exposes a narrow API and dashboard so accounting tools, fintech apps, and marketplaces can sell or automate purchases on top.

The developer workflow is intentionally thin. Customers pull a client library, integrate in one to four weeks, then call Patch from an existing app or backend workflow, such as a purchase flow or a recurring emissions event. Patch handles the hard parts behind the scenes, including supplier contracts, portfolio construction, and post purchase trust layers.

The main inputs are project and registry data from supply partners, plus third party quality and monitoring signals. Patch has described registry data as the minimum bar for listing, then layers on monitoring and partnerships with ratings providers like BeZero. The outputs are searchable project inventory, price and availability, offset estimates, checkout or API purchase flows, and retirement records exposed inside partner products.

That makes Patch complementary to carbon accounting systems like Persefoni. Persefoni gathers activity data across a company, converts fuel, electricity, shipping, and supply chain inputs into emissions, then hands customers off to Patch for procurement. In practice, Patch is the transaction and distribution layer, while accounting platforms are the measurement layer. Nori points to a different model, acting more like a market maker and pricing venue for its own removal supply.
The next step is for carbon procurement to disappear into ordinary software, much like payments did. As more accounting tools, marketplaces, and consumer apps connect to a common carbon transaction layer, suppliers get broader demand without building direct enterprise sales, and buyers get faster, more auditable access to credits with quality data attached at the point of purchase.
