Tributary, the post-award radar for small federal subcontractors

Why it surfaced

Its premise is unusually specific: follow the moment after a prime wins, when ordinary bid-tracking tools stop being useful. The service says it filters open award records, estimates a possible subcontracting slice from past data, identifies a contact, and drafts an introductory email—while promising to leave weak matches out.

Tributary sends small trade subcontractors a morning brief when a federal prime award appears to match their trade, region, and certifications.
