Built for small trade sub-contractors
Evidence only. We pick or pass.
Federal · post-award

Win the subcontract, before the prime starts dialing.

Every weekday morning, you get one short brief: a federal prime that just won work in your trade and your region, an estimated slice of that work that could flow to you, the right person at the prime to contact, and a draft intro email you can send as-is.

We watch every federal prime win every day and only forward the ones the public record actually backs. Weak matches get cut, not softened.

Who it's for

Built for the small trade sub, not the prime-tracking buyer.

The big tracking tools tell you what 's about to be bid. The day a contract is awarded, the chart goes quiet — and that's exactly when a small sub has the shot.

Pre-award tools

Solicitations, drafts, sources sought.

Useful while the RFP is open; the signal disappears the day the award is made.

Tributary

The prime wins, your brief appears.

Recipient, place of performance, a dollar range, the prime's small-business liaison, and a drafted intro email — before sunrise.

How it works

Four quiet jobs, one brief a morning.

Tributary reads open federal award records, picks the ones that match your trade, your geography, and any certifications you carry — then packages what you need to reach the prime first thing.

  1. 01

    We watch the awards

    Each evening, Tributary reads the new federal prime wins of the day from open public records.

  2. 02

    We score the row

    NAICS, place of performance, certification overlap, and the description the prime filed. A row only enters your brief if the public record backs each input — weak matches are cut, not softened.

  3. 03

    We figure a dollar range

    We use past federal sub-award history (FSRS) to compute an estimated slice that could flow to a sub like you. Ranges are bands, not bids, and we don't extrapolate from one data point.

  4. 04

    You get a brief by sunrise

    One short brief per match, in your inbox by 06:00 local: recipient, place, range, contact at the prime, and a drafted intro you can send.

The same matcher, the same gate, and the same source-link layer authentic subscribers see — surfaced from a seed fixture so you can inspect the format before you commit.

  • Tier chip on every row — outreach-eligible, brief-only, or suppressed.
  • Source-link badges — USASpending + SAM.gov, opening the public record in a new tab.
  • Work-package evidence chips — NAICS, PSC, place of performance, and award date.
  • Range copy— the "may be subject to" qualifier when a solicitation value surfaced, italic undisclosed when it did not.

undisclosed

Range withheld — no solicitation value surfaced for this award; verify with the prime before quoting.

Why both branches are shown

The seeded tier-mix fixture deliberately mixes rows with and without a solicitation value, so the "may be subject to" and italic undisclosed branches are both reachable on a single page.

The seeded sample mirrors the live feed — same matcher, same gate. Authentication required to read the full content.

Prime award

Keystone Federal Services, JV

Award W912DY-26-C-0041 · US Army Corps of Engineers · small-business set-aside · NAICS 541512

Work is being performed at: Fort Belvoir, VA

What you can quote for

$1.4M–$2.1M

A dollar range, figured from past federal data about how much of jobs like this typically flow to subcontractors.

How we figure the dollar range

NAICS prefix is matched to a sector ratio drawn from band.ts— services typically 12–14%, specialty-trade construction 32%, IT services 14%, R&D 18%, then transport 16% and admin / waste 22%. On top of that base, a set-aside weight (SDVOSB / 8(a) at 1.10, WOSB / HUBZone at 1.05, SBA 1.00) and an agency-family multiplier (DoD / Navy 1.05, civilian 0.95, VA 1.00, GSA 0.90) are applied to the prime's public award value. The result is then snapped into a ±15% wide band before we surface it.

Why the band is conservative: every input is public, the band is a sanity-check for your outreach — not a bid.

FSRS is the only historical source we use for the band; we don't extrapolate from one data point.

Illustrative bands; the production brief is recomputed from band.ts on the day of the award. What we suppress or label rather than present as fact: a trade inferred from NAICS alone, unverified prime-side contacts, sub-dollar estimates presented as if they were commits, and unsupported compliance or past-performance claims.

Pricing

$199 / month self-serve. Assisted outreach is a gated pilot.

The self-serve plan is open to anyone. Assisted outreach isn't an automatic upgrade — we run it as a small pilot cohort, vet every intro by hand, and set pricing per cohort once we know what the work takes.

Pilot cohort
  • Everything in Self-serve
  • A subscriber-approved intro queue — every introduction is reviewed before any send
  • Pause + bounce controls
  • Direct line to the team running your cohort

Send happens only after you approve each intro, and not before the row's confidence is corroborable. We vet every addressed intro before the queue holds it. Gated pilot — assisted outreach isn't automatic on signup; we're running it with a small cohort first. Pricing is set per cohort once we know what the work takes.
