Opportunity

SAF feedstocks first: a focused entry into an existing value chain.

C1 Foundry's initial customer is a SAF producer or refiner seeking scalable feedstock or intermediate supply. The company does not initially intend to own the complete refinery or finished-fuel value chain.

Commercial product

The first product is a lipid-rich intermediate for downstream SAF upgrading.

C1 Foundry is developing a biological feedstock that can be evaluated against the specifications of SAF producers and refiners. The commercial handoff occurs before finished-fuel production: the material would require recovery, upgrading, pathway qualification, and integration within downstream refining infrastructure.

This focus keeps early development on C1 conversion, metabolic engineering, continuous processing, and product definition rather than adding the capital scope of a complete refinery.

Customer discovery

Twenty-three interviews sharpened the feedstock-first commercialization strategy.

C1 Foundry completed 23 customer-discovery interviews through NSF I-Corps Regional across the SAF ecosystem. Delta Air Lines identified feedstock diversity as important to reducing SAF supply-chain risk. The next validation step is defining the feedstock specifications required by SAF producers and refiners, including participants in Minnesota's emerging SAF ecosystem.

Customer-discovery participation and interview input do not imply a commercial partnership, supply agreement, or endorsement.

Infrastructure fit

Minnesota's SAF activity provides a practical setting for downstream validation.

Minnesota brings together aviation demand, refining capabilities, policy activity, and SAF supply-chain development. That ecosystem can help clarify product specifications and integration requirements, but a biological intermediate cannot move directly to airport blending. It must first be upgraded into qualified SAF through an approved downstream pathway.

Techno-economics

Commercial viability must be earned through process performance and downstream fit.

The business case depends on productivity, titer, yield, culture density, energy demand, hydrogen and co-substrate requirements, recovery, logistics, and downstream upgrading. Market demand does not remove those technical risks; it defines the performance thresholds the platform must meet.

Long-term opportunity

A broader hydrocarbon platform can follow a validated feedstock product.

Over time, engineering fatty-acid and terpenoid-derived structures may support a wider range of hydrocarbon compositions and potentially more complete drop-in fuel pathways. That expansion remains a longer-term opportunity. The first commercial objective is a specified, upgradeable SAF feedstock or intermediate.
