The other two signals

Signal 1Contracts already wonPrimes under a legal obligation to subcontract part of the work. You are chasing a company, not a solicitation.Signal 2Work about to be boughtSources Sought notices. The requirement is not written yet, which is the one moment you can shape it.Signal 3Grants you can apply forFederal funding open to small businesses. Same SAM.gov registration, money that is not a contract.

Where this comes from

Sources sought and presolicitation notices are published by contracting offices on sam.gov, the government's own procurement site. SubSignal reads them daily and keeps the ones that have not closed. Nothing here is filtered by who you are — the free pages show every open notice we hold, and a watchlist is what narrows them to your NAICS codes.
