Sources sought
Sources sought notice (market research)
A sources sought notice is a market-research posting in which an agency asks whether capable vendors — often small businesses — exist for an upcoming requirement. It is not a solicitation; it shapes the acquisition strategy before an RFP is issued.
What it is
Agencies post sources sought (and Requests for Information) during market research to gauge the vendor pool, capabilities, and whether a set-aside is feasible. Responses inform, but don't award, anything.
Why it exists
It helps the government scope the requirement, test small-business capacity, and decide competition strategy before committing to a solicitation.
Who it applies to
Contractors watching for early demand — a sources sought is one of the earliest public signals that a specific requirement is coming, months before an RFP.
