TributaryOne agentic surface for federal capture, environmental compliance, and legislative monitoring.
Replacing SAM.gov digests, RegTech dashboards, legislative trackers, and policy newsletters — one intelligence surface for the way engineering firms actually run federal work.
How Tributary Works
Three steps. From a primary-source signal to a signed draft.
One agent watches the federal record. One routes the signal to your firm. One drafts the deliverable — cited at the footnote, ready for counsel to redline.
- Step 01 · Watch
We watch SAM.gov, Federal Register, and Congress.gov.
Continuous primary-source monitoring — your inbox sees the comment window before it closes, not the digest two weeks after.
- Step 02 · Match
We match it to your firm.
Every signal is scored against your NAICS, capabilities, and past performance — so your team reads only what closes for you.
- Step 03 · Draft
We draft the proposal or position paper.
A citation-backed first draft lands in hours, footnoted to the Federal Register paragraph, the SAM.gov opportunity ID, and the committee report — ready for counsel to redline.
From signal to signed draft — usually under a business day, every line tied to a primary federal source.
See plans →The Platform
Three agents. One continuous watch.
Each channel is an agent that scans primary sources, signals on what matters for your firm, and drafts first-pass deliverables with cited footnotes. You route the intelligence; the agents do the watching.
- Channel 01
Federal Capture
A long-cycle agent that watches SAM.gov, agency forecasts, and prime pipelines — surfacing matched opportunities before they hit the bid list.
- SAM.gov + agency forecasts + historical prime award data
- Tracks forecasted vs awarded set-asides, NAICS drift
- First-draft capture plans tied to your past performance
- Channel 02
Environmental Rulemaking
A continuous reader of NEPA, E.O. 13891 rollback actions, EPA NSPS/NSR, SEC climate disclosure, and state permitting dockets.
- EPA, CEQ, FERC, and 12 state permitting portals
- Comment-window and conformity-flag detection
- Cited briefs ready for your environmental counsel
- Channel 03
Legislative Monitoring
Tracks federal committee markup, conference reports, and the daily Congressional Record — so policy moves surface before the newsletter does.
- House / Senate committee amendments + manager’s marks
- Conference report diff and conference rider flagging
- Position-paper drafts citing the exact section number
Outputs
Drafts that hold up under legal review.
Every agent ships a first-draft deliverable — not a dashboard widget. Proposals, position papers, briefing memos, and deadline alerts arrive with primary-source citations, an export trail for FOIA and disclosure, and a copy-edit pass your counsel can then redline rather than assemble from scratch.
Compliance by design
Cited at the footnote. Exportable by the FOIA officer.
Every line in every output links back to a primary source — Federal Register paragraph, docket ID, Congressional Record page, agency press release. The same trail that lands in your brief is the trail a FOIA officer exports; nothing in Tributary is dark to internal legal.
Citation footer — draft proposal re: Buy Americaoutbound · 2026-08-05
We recommend the prime substitute mill-certified domestic steel at the structural-plate stage and re-issue the BABA affirmation, given the agency’s clarification on on-shored rolling.
CITE 01
Federal Register · 88 FR 79403
“for the purposes of Buy America Build America, rolling, slitting, cutting, and other finishing operations carried out in the United States qualify as domestic processes.”
CITE 02
DOT NHTSA Memo · 2025-04-12
“agency will not waive BABA on a per-award basis absent a documented industry-wide capacity gap verified by BLS industrial-output index.”
CITE 03
Congressional Record · H.R. Rep. 117-xxx § 410
“the manager’s amendment restores the previously-deleted clause clarifying that a state DOT may reopen the domestic-sourcing review.”
Programs we watch
Built for the unprecedented infrastructure cycle.
Tributary covers the unusually heavy compliance surface tied to the federal programs engineering and AEC firms have been working through since 2021 — with the cross-agency environmental reviews and oversight structures those programs triggered.

- IRA
Inflation Reduction Act
- CHIPS

Built by practitioners
The intelligence stack the founders kept rebuilding in-house.
The founding team has led federal affairs, capture, and policy work inside one of the largest global engineering organizations through the IIJA, IRA, and CHIPS cycles — Tributary is the workflow they kept rebuilding in-house, finally shipped as a single agentic surface so engineering and AEC buyers can route the same intelligence into capture, policy, and compliance without babysitting a stack of disconnected tools.
