Mentor-Protégé Relationships

SBA ASMPP and DoD Mentor-Protégé Program affiliations

GovChime will sync Mentor-Protégé agreements for STG LLC once the dedicated MPP ingestion pipeline ships. Agreement data is held in separate SBA and DoD administrative registries without a public REST API, so this profile does not yet include ASMPP or DoD MPP status.

Coming soon — MPP data ingestion is tracked on our roadmap. Sources when live: SBA All Small Mentor-Protégé Program (ASMPP) and DoD Mentor-Protégé Program.
