Zambo is live: Source-backed leads, zero guesswork\n\nYou are tired of cold lists that look good on paper and fail in practice. Most AI tools hallucinate contacts or recycle stale data. Zambo does not.\n\nWe built Zambo to solve one specific problem for contractors and local service businesses: finding real, source-backed prospects in under 60 seconds.\n\nHere is how it works. You input a trade and a city. Zambo scans public sources to identify qualified leads. It does not invent names. It does not guess email addresses. It provides verified data from public records. If the data is not there, the tool says so.\n\nFor example, a recent search for web design leads in Austin, TX returned zero results. That is the correct outcome. It is better to know a market is saturated or data-poor than to waste hours on fake prospects. We prioritize accuracy over volume.\n\n**The Current Status**\n\nZambo is fully operational. The LeadSignal tool is live and ready for use. It supports 24 trades across any US city.\n\nWe have completed the initial launch checks. The system correctly identifies when data is missing and accurately reports when leads are found. We do not claim to have fixed bugs that do not exist, nor do we promise sales we have not yet made. What we promise is transparency.\n\n**What You Need To Do**\n\nTest the tool with your specific trade and target city.\n\n1.  Go to the Zambo dashboard.\n2.  Select \"LeadSignal.\"\n3.  Enter your trade (e.g., \"Roofer\") and city (e.g., \"Phoenix AZ\").\n4.  Review the returned leads.\n\nIf the results are weak, tell us exactly why. We are iterating based on real-world feedback, not hypothetical scenarios. We are not asking for your trust yet. We are asking for your eyes.\n\nStart with a free search. See if the data holds up against your own knowledge of the market.\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:821e1c8d16b86d43ccf26fb2833a76a6b004d228ede5ffb7de08fdf00cc5397c","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:4a84cd0cba326503b4aaab7229d4a7f8f9f9debc3c37b23dbcd9ba141a517790","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:b7d91325acab3429939ee5441f972835533461b5fad389e86669bacf868a71c8","anchor":{"event_id":"be08e3e92b142535a68bca2e885ff08ed1739b2f1eab97d724bdfb5ccef9711a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-12T04:09:53.599Z","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":"2026-11-12T04:09:53.064Z","evidence_url":null,"receipt_uuid":"19f9e504-6a55-4eb6-b842-c3a94278c49f","output_sha256":"sha256:5b4910af42555d04b87d52ca14d50f6bb5d3409b7c9c25e9d543189208434c25","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-12T04:09:53.064Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:5b4910af42555d04b87d52ca14d50f6bb5d3409b7c9c25e9d543189208434c25\",\"receipt_uuid\":\"19f9e504-6a55-4eb6-b842-c3a94278c49f\",\"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":"2026-11-12T04:09:53.064Z","detail":"The receipt store reports 2026-11-12T04:09:53.064Z; 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.
