Search public tenders across Europe and the UK — TED (all 27 EU member states), the UK Find a Tender Service & Contracts Finder, TenderNed (NL), e-Procurement/BDA (BE), oeffentlichevergabe.de (DE) and BOAMP (FR). Semantic search plus filters by country, sector (CPV), nature and open-for-bidding. Returns AI summaries, matching tags and who-won (award) data.
Example: "Find open IT-services tenders in the Netherlands and Belgium published this month"
United States — the tools below cover US federal procurement:
Search SAM.gov for active RFPs, RFQs, sources sought, and pre-solicitations. Filter by keyword, NAICS code, agency, set-aside type, and date range.
Example: "Find SDVOSB set-aside IT contracts from DOD posted in the last 30 days"
Retrieve the full description and attachments for a specific SAM.gov opportunity by notice ID.
Search USASpending.gov for past federal contract awards. Use for competitive intelligence, price-to-win research, and agency spending patterns.
Example: "Who has DHS awarded cybersecurity contracts to in 2024?"
Search Grants.gov for federal grant opportunities across all agencies. Filter by category, agency, and status.
Cross-source sweep across SAM.gov and Grants.gov simultaneously in a single query. Best starting point for a new opportunity area.
Example: "Scout all sources for zero trust cybersecurity opportunities"
Get total federal award counts and amounts by keyword from USASpending. Use for market sizing before pursuing a contract vehicle.
Search FPDS-NG for detailed contract award history. Best for incumbency research — find who holds a contract, what it pays, and when it expires.
Example: "Who is the incumbent on Army IT support contracts in Virginia?"
Search Federal Register notices and proposed rules for early procurement signals. Agencies publish RFIs and pre-solicitation notices here before SAM.gov.
Search Regulations.gov for proposed rules and public comments. New regulations drive new contracts — mandates create procurement demand.
Search GovInfo for GAO reports, budget justifications, and congressional committee prints. GAO audit findings predict future contract areas.
Example: "Find GAO reports on VA healthcare IT failures"
Search USAJobs for federal hiring surges. When an agency posts a wave of IT or cybersecurity jobs, contract awards in that area typically follow within 6–12 months.
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.
Example: "Find HUBZone-certified cybersecurity firms in Virginia"
