Postor
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Postor AI Bid Team takes a small business from a real public tender to an honest answer: GO, GO WITH CONDITIONS, NO GO or NEEDS REVIEW, plus a bid-ready draft when bidding makes sense. --- For judges: open the live demo at https://demo.postor.do and, on the sign-in page, enter the access code ("3dee7c965d882447") and your own Meta Model API key. The key powers the live analyses: it stays in your browser tab, travels only with your requests to Meta and is never stored by our server. Suggested 3-minute path: Opportunities → open Case A → ▶ Run live analysis (Fast mode, ~2 min) → Analysis (verdict, conditions, financial ratios) → Requirements (click any "pliego pN" to see the cited page of the original PDF) → Trace (every Meta model call with prompt, response, tokens and estimated cost). Then compare Cases C and D: same pipeline, different verdicts, each for a cited reason. The four tenders also include recorded runs to browse while a live analysis runs. The README has the full walkthrough. --- The problem: so far in 2026, the Dominican state has awarded more than RD$437 billion in public contracts (RD$324B in 2025, RD$191B in 2024). Every peso goes through a tender that a small business has to read page by page, and bids are lost on paperwork: a missing certificate, an expired document, a requirement found too late. Postor is a live, paid SaaS at postor.do with a small base of paying customers. Before this hackathon it helped companies find tenders and see what each one asks for. With Meta's models we built the rest of the path: - Reads the real tender (pliego, amendments, official forms), never modified, every page screened for prompt injection. - Checks each requirement against the company's own evidence (certifications with expiry dates, projects, finances, team), citing document + page on both sides. - Decides with deterministic guards: financial ratios, revenue concentration and mandatory pass/fail criteria are code, not model output. - Drafts the technical proposal, has a second model (Muse Wonder) audit it, fills the tender's own forms and prices the F.033 economic offer at ~97% of the budget, tax included, with the total in words. - Leaves the human in charge: anything unproven stays [PENDING], and the bid manager can answer by voice. Postor never submits, signs or sends. On 4 real Dominican tenders the same pipeline says go, no go or needs review for the right reasons; a contract worth 86% of the company's revenue goes to a human. Every model call is traceable (prompt, response, tokens, duration, estimated cost). The demo company is fictional and marked DEMO; the tenders are real public records.
