Zambo is live: 60-second lead generation\n\nHi [Name],\n\nZambo Stack is now available. It solves one specific problem: finding qualified leads for local service businesses without the usual days of manual scraping.\n\nHere is the reality of the current launch state. We tested the `leadsignal` tool for web design prospects in Austin, TX. The system executed the search successfully but returned zero source-backed results for that specific trade and city combination right now.\n\nThis outcome is critical for your understanding of the product. Zambo does not hallucinate data. It does not generate fake names or invented phone numbers to make a demo look impressive. It returns only verified, source-backed prospects. If the data isn’t there, the tool tells you so.\n\nThis distinction matters. Many AI lead gen tools produce plausible-sounding but incorrect data. Zambo prioritizes accuracy over volume. A receipt proves the bytes saved. It does not prove the data is correct. The tool’s value lies in its ability to filter noise and surface only real, actionable contacts when they exist.\n\nWe are currently researching public, source-backed prospective customers for an AI tools product launch. This is a research-only phase. We are not sending outreach. We are not claiming customers. We are identifying where the tool performs well and where it encounters gaps, like the Austin web design test above.\n\nThe tool supports 24 trades and any US city. It offers three free searches per day per IP. No authentication is required for the initial trial.\n\n**Next Step:**\n\nReview the attached receipt for the Austin test run. It documents the exact query, the zero-result status, and the quota usage. This transparent log is part of the product’s integrity. You can verify the run ID directly through the provided link.\n\nLet’s discuss how this accuracy-first approach fits your current lead generation workflow.\n\nBest,\n\n[Your Name]\nZambo Stack\n[Link to Receipt: https://zambo.dev/run/cfc8c1af-8243-438e-b161-2871b9a3de78]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:073077f989d9309e012a4940bd1bba382d3c13e7de9157d7d700f836eea89d90","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:3c79744ab40db1e378400326e3f40766dc332c920b59b77d13c1600a9d0b24ce","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:b651e7efa390600af21db935605648456256f768533ac7055e278237b9678407","anchor":{"event_id":"772c78b5757b0b825ee456ba95c8cbab9b5aa79589dc2caa680ac9cd8c1ba8ae","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-04T21:45:29.683Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-04T21:45:29.072Z","evidence_url":null,"receipt_uuid":"93c7f12e-36f2-4f51-bb18-a929e853b4d6","output_sha256":"sha256:0fb83dee89e1d633a124a81f54926f86fb97e902e54e73f9ead66dd28eda7aed","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-04T21:45:29.072Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:0fb83dee89e1d633a124a81f54926f86fb97e902e54e73f9ead66dd28eda7aed\",\"receipt_uuid\":\"93c7f12e-36f2-4f51-bb18-a929e853b4d6\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-11-04T21:45:29.072Z","detail":"The receipt store reports 2026-11-04T21:45:29.072Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
