Sells patented combustion and sensing technology that OEMs and partners embed in industrial products. Its asset-light model serves energy, refining, boiler, chemical, petrochemical, transport, and power applications.
Patented ClearSign Core combustion technology and ClearSign Eye sensing configurations are designed to be embedded in established OEM products. The company targets energy, refining, commercial and industrial boiler, chemical, petrochemical, transport, and power applications.
Its model is asset-light: it commercializes technology through established OEM and partner offerings in end-market equipment rather than a broad standalone manufacturing footprint. A co-branded process-burner line with Zeeco is marketed by both companies’ sales teams.
Commercialization, IP protection, and working capital depend on adequate funding from co-development arrangements, strategic partnerships, or equity and debt financing.
