Twelve is a carbon transformation company founded in 2015 and headquartered in Berkeley, CA. Carbon transformation company making E-Jet sustainable aviation fuel and chemicals from CO2, water, and renewable electricity. Public revenue is not disclosed; the best scale signals are 300+ estimated employees, $800M+ incl. project financing in disclosed funding or financing, and named strategic customers, investors, or project partners.
The company operates in a market where buyers care about technical proof, safety, regulatory execution, deployment reliability, and bankable unit economics. Its product surface includes AirPlant One, E-Jet SAF, E-Naphtha, eMade / CO2Made products, with commercialization tied to long sales cycles and real-world deployment milestones.
For sellers, Twelve should be treated as a sophisticated technical buyer rather than a conventional SaaS account. Engineering and operations leaders shape architecture, finance and legal shape contract structure, and executives usually become involved when the purchase touches strategic capacity, manufacturing, safety, or regulated deployment.

How does Twelve make money?
Twelve sells fuels and chemicals through offtake agreements, strategic partnerships, and project-backed AirPlant production rather than software subscriptions.
Twelve sells fuels and chemicals through offtake agreements, strategic partnerships, and project-backed AirPlant production rather than software subscriptions. The company does not publish simple self-serve pricing because contracts are tied to deployment scope, physical capacity, engineering services, risk allocation, and long-term operating obligations.
Fuel pricing is not published; contracts are negotiated around long-term electricity costs, CO2 supply, SAF certification, delivery logistics, book-and-claim accounting, and multi-year airline/corporate offtake. Growth is driven by converting technical proof into repeatable commercial deployments, then expanding with customers or partners that can absorb larger volumes, additional sites, or more mission-critical workloads.
Unit economics depend less on seat expansion and more on utilization, manufacturing yield, project execution, contract duration, and the cost of capital. As Twelve scales, procurement becomes more formal: vendors should be ready for safety, security, quality, compliance, and finance reviews before broad rollout.
