Zambo is live: AI lead gen for local trades\n\nHi [Name],\n\nZambo is officially launching. We built this specifically for contractors and local service businesses who need qualified leads faster, without the high cost of traditional ad spend.\n\nOur core tool, LeadSignal, takes a trade and a city, then returns five source-backed prospective contacts in under 60 seconds. It supports twenty-four different trades across any US city. The platform is designed to be strictly research-focused; it generates leads and drafts messages but never sends outreach automatically. You retain full control over every interaction.\n\nWe are currently on a free tier that allows three searches per day per IP address. This is a direct test of the workflow: you input your specific needs, and the system provides verified, real-world prospects based on public data. No invented names, no fake sales, just actionable research.\n\nWe have already run initial checks on the infrastructure. For example, a recent query for web designers in Austin, TX returned zero results, which accurately reflects the current data availability for that specific niche in that location. This transparency is key. If the data isn’t there, we tell you clearly rather than padding the list with unverified guesses. We prioritize accuracy over volume.\n\nYour next step is simple. Test the system with a trade and city you are actively targeting right now. Use the free daily quota to see if the returned prospects match your ideal customer profile. If they do, you have a starting point for genuine conversation. If not, you know exactly which data gaps exist.\n\nThis is a tool for precision, not magic. It removes the guesswork from lead sourcing by grounding every request in verifiable public information.\n\nLet me know what trade and city you want to test first.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e9eac8a2d0f32beba617a1400390840d26fb0da0db1f653c6cf27bbeb5e99d74","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":"sha256:9721ebffd6ded9bf2f636c9272fe34a8e406bb8681540a9838d8901c46ef56c9","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:d01743150c3e1de8bb68a5c6c5f9e413d6229e99dcbd812c48a9e49eb20209d9","anchor":{"event_id":"f565c0857467a1d9a6becaefeeec97a2b5abec52f9d755ae27b4c50966ddea75","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-07T06:49:38.030Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-07T06:49:37.283Z","evidence_url":null,"receipt_uuid":"9829517b-8781-4d84-bf8c-45c01d550538","output_sha256":"sha256:3e5b46be8f74714a210f7dd48b2ae4da97d0ba01f0cbe61f43f474115887fe24","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-07T06:49:37.283Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:3e5b46be8f74714a210f7dd48b2ae4da97d0ba01f0cbe61f43f474115887fe24\",\"receipt_uuid\":\"9829517b-8781-4d84-bf8c-45c01d550538\",\"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":"2026-11-07T06:49:37.283Z","detail":"The receipt store reports 2026-11-07T06:49:37.283Z; 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.
