Stellar J Corporation

Stellar J Corporation

Stellar J Corporation operates as a merit-based, employee-owned company from its headquarters in Woodland, Washington. Bob Kinghorn founded the firm, and Jeff Walker co-founded it alongside him, building a leadership team that includes President Jeff Carlsen and CFO Cheryl Subasic. The firm's structure as an employee-owned entity sets its incentives apart from private-equity-backed engineering and construction firms. The firm's project portfolio spans three primary verticals: renewable natural gas, heavy civil infrastructure, and hydrogen. As an EPC contractor, Stellar J designs, develops, and builds renewable natural gas production plants for dairy farms and waste facilities, and it constructs hydrogen plants alongside the renewable electricity processes that power them. Its heavy infrastructure work covers water and wastewater plants, bridges, and marine terminals. The firm's role as the EPC contractor on Raven's green hydrogen project in Northern California demonstrates a direct stake in the energy transition's physical buildout, operating nationally rather than regionally. Stellar J remains privately held by its employees, and financial scale — whether revenue, AUM, or deployment — is not publicly disclosed. No adjacent investment vehicles, philanthropic foundations, or external club memberships are mentioned in its public footprint. The firm's website emphasizes a "scoreboard" of metrics, including projects completed and on-schedule delivery rates, but does not publish underlying numbers or dates. Stellar J's structural differentiator is its identity as an employee-owned EPC contractor that also acts as a project developer. This hybrid model — where the builder has an ownership mindset in the projects it executes — combines construction execution with development economics, creating an alignment mechanism that is distinct from the typical general contractor.
