Zambo Launch: Source-Backed Leads, Zero Invention\n\nHi [Name],\n\nZambo is live. We stopped guessing who your customers are.\n\nOur lead generation engine doesn’t list generic directories. It finds verified, source-backed prospects for your specific trade and city. If a lead isn’t backed by public data, it doesn’t appear. No invented names. No fake phone numbers. Just real businesses ready to talk.\n\nWe are currently supporting 24 trades across the US. The system provides five qualified leads in under sixty seconds. It is free to use, with no authentication required. You get three searches per day, per IP.\n\nWe tested this today. We ran a query for web design firms in Austin, Texas. The result was zero leads. The system correctly identified that no source-backed prospects existed for that specific combination at that moment. It did not fill the gap with hallucinations. It returned a clean, honest empty state.\n\nThat is the core difference. Most AI tools will invent a \"John Smith\" to look helpful. Zambo tells you the truth: there is no one there. This ensures that when you do find a lead, you can trust the contact details. A receipt proves the saved bytes are unchanged, not that the data is perfect, but it guarantees integrity.\n\nWe are not claiming this is a magic bullet. We are offering a tool that respects your time by refusing to waste it on fake data.\n\n**The Next Step**\n\nWe want to see if this works for your specific niche. Pick a trade you know well and a city where you operate. Run one search.\n\n1.  Go to [Zambo Link].\n2.  Enter your trade (e.g., Roofer).\n3.  Enter your city (e.g., Phoenix, AZ).\n4.  Check the results.\n\nIf you find source-backed leads, you have a starting point. If you don’t, you know exactly where the market is quiet. Either way, you save time.\n\nWe are not asking you to sign up for a trial. We are asking you to test the engine. If the leads look real, let’s talk. If they don’t, we need to know why.\n\nReply with the trade and city you want to test. I will run it and send you the direct receipt link.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:5e0ac6f4dd786e97d613d8e88fa31dd172d168b5f3e80ab3d7cd2b6a3d7ad65e","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:b416b1c80763451a553959a3341f3126a987c7ef74d551832453185857ee6a9e","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":"sha256:0d45d38eaffe9986d1b83ecb5cea59cf67cc09e927e80d87ba54ca9b1b7adbd7","anchor":{"event_id":"db8fe1680f84ac8600ef70cc53c4cc91fb6f7b0ca3e33c2695737bfac07cdd0b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T17:15:44.905Z","published_at_semantics":"Relay confirmation time (accepted acknowledgement or exact-event read-back); not the signed event's created_at.","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-08T17:15:44.351Z","evidence_url":null,"receipt_uuid":"42406f94-99cd-4178-ae8f-60d2a8c42347","output_sha256":"sha256:51c13569484f3e0b1953cd7432964895076ecbfdaec825281f74f77b559a12d1","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T17:15:44.351Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:51c13569484f3e0b1953cd7432964895076ecbfdaec825281f74f77b559a12d1\",\"receipt_uuid\":\"42406f94-99cd-4178-ae8f-60d2a8c42347\",\"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":"2026-11-08T17:15:44.351Z","detail":"The receipt store reports 2026-11-08T17:15:44.351Z; 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.
