What is a sources sought notice?
A sources sought notice is market research an agency posts before a solicitation to find capable businesses — often to decide whether the buy can be set aside for small business. Answering it can influence how the requirement is written and whether the set-aside happens, which no proposal can do.
Sources sought versus RFI
They overlap and agencies use the terms loosely, but the intent differs. A sources sought is usually about capability and market composition: who can do this, and are enough of them small? A request for information is usually about approach: how would this be done, what does it cost, what is technically feasible. Answer a sources sought with capability evidence; answer an RFI with substance about approach.
Why the window matters
By the time a solicitation posts, the requirement is written and the evaluation criteria are fixed. At sources-sought stage none of that is settled. A well-evidenced response from three capable small businesses is how a requirement becomes a small-business set-aside.
How to answer one well
Address the specific NAICS and the specific work described. Cite past performance with agency, value and dates — capability claims without evidence are discarded. State your set-asides and certifications plainly. If you can do 80% of the scope and would team for the rest, say so and name the teaming shape: agencies are researching the market, not scoring you.
What it is not
It is not a proposal and it does not obligate anybody. It is also not optional if you want to compete on a requirement that has not been shaped yet — the firms in the winner's circle on recompetes are usually the ones who were in the room a year early.
