No invented data. Just a working tool for local service businesses.\n\nZambo Stack is officially live. It solves one specific problem: finding qualified, source-backed leads for contractors and local service providers without the usual manual research grind.\n\nHere is what the product actually does:\n\n1.  **Speed:** You input a trade and a city. You get five qualified leads with contact info in under 60 seconds.\n2.  **Scope:** It supports 24 trades across any US city.\n3.  **Access:** It is free to start. Three free searches per day per IP. No authentication required.\n\nWe ran a test query for web design firms in Austin, TX. The result was zero leads for this specific sector right now. That is the point. The tool does not hallucinate prospects. It returns only what exists in the source data. If a lead isn’t there, it tells you so. This accuracy is the core value proposition: you get a clean slate, not a list of junk contacts.\n\nThe platform also includes a universal entry point routing through 36 other tools, including strategy AI and code audits, but lead generation is the headline feature for this launch.\n\n**Next Step:**\n\nTest the engine yourself. Go to `zambo.dev` and run your first search. Pick your trade and city. If the tool finds no leads, that is a valid data point, not a bug.\n\nIf you see value in the speed and the accuracy, we want to hear your feedback on the output quality. Reply to this email with one trade and one city you want to test. We will run it and share the raw results with you directly.\n\nNo sign-up required for the first look.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:5f7f526fa1518026c3c6efdc85a1d77224a0576eecb864b080bde9124a40224d","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":"sha256:776f1d8c6fbc187dad4a036ba8b3b61b9f0aca72066cad663b7c01939fd32101","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:d223aa7ecbaaa243ab927e0e811707bb82a8cf53d32d05be7c37e183ecb01c5d","anchor":{"event_id":"b9a6a10c276a08729b77fdc5282e7bfa2c1cd697f8a1825e454787f90dfefcbb","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-31T02:13:10.555Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T02:13:10.017Z","evidence_url":null,"receipt_uuid":"df287531-08e2-4161-bb76-4183437d277e","output_sha256":"sha256:cd31ea41fd004841cee219898db1f953b20f9019c9b5d9bdf22e5dc6dbf85db6","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T02:13:10.017Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:cd31ea41fd004841cee219898db1f953b20f9019c9b5d9bdf22e5dc6dbf85db6\",\"receipt_uuid\":\"df287531-08e2-4161-bb76-4183437d277e\",\"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":"2026-10-31T02:13:10.017Z","detail":"The receipt store reports 2026-10-31T02:13:10.017Z; 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.
