As answered by people managing LeetCode and TenderVault.io.
TenderVault.io's answer:
TenderVault is the only government contracting platform that's both globally unified (90+ countries in one feed) and AI-native (proposal drafts, bid/no-bid scoring, automatic translation) — at a price built for the businesses actually winning these contracts, not the 50-person BD teams chasing them.
TenderVault.io's answer:
Because every other option forces a tradeoff you shouldn't have to make: Bloomberg Government and GovWin give you depth but cost $5,000+/month and only cover one or two regions. SAM.gov, Contracts Finder, and TED are free but country-locked, search-only, and have zero workflow tools. International aggregators like TenderTiger or DgMarket are global but have no AI, no pipeline, no analytics, and a 2008 UI.
TenderVault is the only platform that is global, AI-native, workflow-complete, and self-serve priced — all at once.
TenderVault.io's answer:
TenderVault is built for the businesses, solo bid writers, and consultancies who actively bid on government contracts globally — but have been priced out of the $5K/month enterprise tools the big primes use.
TenderVault.io's answer:
A friend's consultancy lost a $400K government contract — not because their proposal was weak, but because they found the RFP three days before the deadline. The opportunity had been live for six weeks. The incumbent — a 200-person firm with a $5,000/month Bloomberg Government subscription — had been working on it from day one.
That asymmetry stuck with me. Public procurement is supposed to be public. In practice, the information is gatekept by tools priced for defense primes, not the small businesses who actually win most of these contracts.
I built TenderVault to fix that.
