An AI-native alternative for tender search
Most tender-alert tools are standalone web portals: you log in, build a saved search, and read a list. TenderStack takes a different approach — it puts live procurement intelligence directly inside the AI assistants you already use, across more markets, with intelligence that goes beyond a list of links.
How TenderStack is different
- AI-native, not another login. Search from inside Claude or ChatGPT in plain English. There's also a web app if you prefer one.
- EU + UK + US in one account. All 27 EU states via TED, the UK (Find a Tender + Contracts Finder), the Netherlands, Belgium, Germany and France, plus US federal sources. See EU, UK and US coverage.
- Above and below threshold. It ingests national portals (DE, NL, BE, FR, UK Contracts Finder, US) where the smaller, less-contested contracts live — not just the headline EU-wide notices.
- Semantic search. Match on what your company actually does, in any language — no memorising thousands of CPV codes.
- Who won, and what's next. Award data with the winning supplier and value where published, plus forecasting of contracts likely to return to market, with the incumbent named.
- Beyond discovery. Pull full documents (with OCR) and draft a first-pass proposal in the same chat.
Honest about the trade-offs
An AI-native approach is a different model, and it's only the right fit for some teams. If you specifically want a fixed visual dashboard with no AI involved, a conventional portal may suit you better. TenderStack's strengths are breadth of coverage, plain-language search, and the intelligence layer (who-won, re-tender forecasts, document analysis, drafting) — delivered where you already work rather than in yet another tab.
What TenderStack does not do
TenderStack is a read-only intelligence layer over official public sources. It doesn't submit bids on your behalf or alter government data. For a full collaborative bid-management workspace — institutional memory, jurisdiction skills, approvals and audit trail — LemonB BV (the team behind TenderStack) also builds the wider TenderB platform. TenderStack is the open front door to it.

What makes TenderStack different from a traditional tender portal?
TenderStack is AI-native: instead of logging into a separate dashboard, you search live tenders, awards and grants from inside Claude or ChatGPT using plain language. It covers the EU, UK and US — above and below threshold — with semantic search, who-won data and re-tender forecasting.
Does TenderStack cover the EU, UK and US together?
Yes. One TenderStack account covers all 27 EU states via TED, the UK (Find a Tender and Contracts Finder), the Netherlands, Belgium, Germany and France, plus US federal sources (SAM.gov, Grants.gov, USASpending and more). Many portals focus on a single country or region.
Can I try it for free?
Yes. TenderStack has a free plan with 200 actions a month. Pro is $49/month for unlimited searches and Team is $199/month for 5 seats, then $39 per extra seat. No sales call required to start.
Does it just search, or can it help me bid?
Both. Beyond search, TenderStack pulls full solicitation documents (with OCR), shows who won past contracts, forecasts contracts likely to return to market, and drafts a first-pass proposal — all in the same conversation.
