Patch as Carbon Commerce Connector
Brennan Spellacy, CEO of Patch, on the API layer of the carbon stack
Patch is trying to become the connective tissue of carbon commerce, not just another offset seller. The hard part in this market is that emissions data lives in accounting tools, project quality data lives in ratings and registry systems, and actual credit procurement happens somewhere else. Patch sits in the middle, turns fragmented supply into one API and dashboard, and lets accounting platforms and product teams add carbon purchasing without building that infrastructure themselves.

For a company trying to reach net zero, the minimum stack already spans at least two separate systems, a carbon accounting product to measure emissions and a carbon credit product to buy removals. Patch is built for that gap, and can be embedded inside tools like Persefoni so the buyer sees one workflow instead of stitching vendors together manually.
-
The operational mess is concrete. Without an intermediary, a buyer building a portfolio across 10 to 15 projects may need 10 to 15 contracts and direct supplier relationships. Patch standardizes supplier onboarding, legal terms, inventory management, and post purchase monitoring, which makes the market feel more like software procurement than bespoke brokerage.

This position also explains why Patch partners well with accounting vendors and why others in the stack stay specialized. Persefoni treats offset procurement as complementary and ethically separate from accounting, while Nori aimed to rebuild carbon market rails with tokenization and more transparent pricing. Patch is the integration layer that helps existing enterprise systems transact today.
If this layer becomes standard, Patch starts to look less like a climate app and more like payments infrastructure. The winning platform will be the one plugged into CFO workflows, accounting systems, and buyer applications by default, so carbon procurement happens inside normal business software instead of as a separate project every time.
