Search US government contracts with AI
US federal procurement intelligence is scattered across a dozen government systems. TenderStack connects the most important ones to Claude and ChatGPT, so you can find live opportunities, see who won past work, and research incumbents in plain English.
The sources, connected to your AI
- SAM.gov — active RFPs, RFQs, sources-sought and pre-solicitations.
- Grants.gov — federal grant opportunities across all agencies.
- USASpending.gov & FPDS-NG — past award and spending history, for incumbency and price-to-win research.
- Federal Register & Regulations.gov — early signals; agencies often post RFIs and proposed rules before a solicitation hits SAM.gov.
- GovInfo & USAJobs — GAO reports and budget justifications, plus federal hiring surges that frequently precede contract awards.
Find live opportunities
Search SAM.gov by keyword, NAICS code, agency, set-aside type and date range. Because TenderStack also reads meaning, you can ask broadly and let it rank:
- "Find SDVOSB set-aside IT contracts from DOD posted in the last 30 days."
- "Scout all sources for zero-trust cybersecurity opportunities."
Research who won — and who's vulnerable
Use USASpending and FPDS-NG to see who holds a contract, what it pays and when it expires. Ask "who is the incumbent on Army IT support contracts in Virginia?" or "who has DHS awarded cybersecurity contracts to in the last two years?" Pair that with the forecasting tools to find contracts expiring soon that are likely to return to market.
Find teaming partners and check eligibility
TenderStack can search SAM.gov entity registrations to find teaming partners, verify socioeconomic certifications (8(a), WOSB, HUBZone, SDVOSB), or look up a company by UEI or CAGE code — for example, "find HUBZone-certified cybersecurity firms in Virginia."
One key, US plus EU and UK

How do I search SAM.gov with AI?
TenderStack connects SAM.gov to Claude and ChatGPT. Sign up for a free key, connect the tool, and ask in plain English for active RFPs, RFQs, sources-sought and pre-solicitations — filtered by NAICS, agency, set-aside type and date range.
Can I see who won past federal contracts?
Yes. TenderStack searches USASpending.gov and FPDS-NG for past federal awards, so you can research incumbents, benchmark price-to-win, and analyse agency spending patterns — for example, 'who has DHS awarded cybersecurity contracts to since 2023?'
Does it cover federal grants too?
Yes. TenderStack searches Grants.gov for federal grant opportunities across all agencies, and the scout_all tool sweeps SAM.gov and Grants.gov together in a single query.
What other US procurement signals does it cover?
Beyond SAM.gov, Grants.gov and USASpending, TenderStack reaches FPDS-NG (award history), the Federal Register and Regulations.gov (early procurement signals), GovInfo (GAO reports and budget docs) and USAJobs (federal hiring surges that often precede contract awards).
