The same capability, commercially
Commercially, R425 is the technical-advisory engagement: bringing engineering and technical expertise to a specific problem. Mid-market and enterprise firms buy this for technical assessments, feasibility work, and specialized engineering support. The capability is the same as the government version, sold on the problem rather than a code.
Mid-market, SMB, and enterprise buyers.
A PSC only matters when the buyer is a federal agency. The underlying service is the same for commercial buyers.
