Zambo is live: AI lead generation for local service businesses\n\nI’m writing to let you know Zambo has officially launched.\n\nWe built Zambo to solve a specific problem for contractors and local service providers: finding qualified prospects without spending hours on manual research. Our tool, LeadSignal, scans public sources to provide five qualified leads with contact information in under 60 seconds. It supports 24 trades across any US city.\n\nTo ensure you understand exactly what you are getting, here is the current status of the platform based on recent test runs:\n\n1.  **Functionality:** The execution plan is fully executable in chat. You input a trade and a city (e.g., \"roofer\" in \"Phoenix AZ\"), and the system returns source-backed research and a draft message. It does not send outreach; it gives you the data you need to send it yourself.\n2.  **Transparency on Results:** We recently ran a query for web design leads in Austin, TX. The result was zero leads. This is not a bug. It reflects the current availability of source-backed data for that specific niche and location. We do not fabricate numbers. If the data isn’t there, we tell you.\n3.  **Security and Integrity:** Our system undergoes deep semantic analysis and pattern checks. We actively block jailbreak attempts, prompt leaks, and PII extraction. A receipt URL is provided for every run, which proves the saved bytes of the interaction. Note that a receipt confirms the data was saved as requested; it does not guarantee the commercial correctness of the leads themselves.\n\nYou currently have access to the free tier, which includes three searches per IP per UTC day. No authentication is required to start.\n\n**Next Step:**\nRun a test query for your primary trade and city. Verify the returned leads against your own criteria. If the data aligns with your needs, keep using it. If not, let us know. We are building this based on real-world feedback, not hype.\n\nCheck out the tool here: https://zambo.dev\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:00ff784b840627aaf644188f160d5328882228d0873bfaac140b2aba109c01f8","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:a2f337ce55a3b94d7bb8580c9ae9d718b4437fc3f85235e27c691adb472296ee","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":"sha256:31199b6a844dbea9648932eca169f153c77b3a38715988466727d817026a215b","anchor":{"event_id":"59c811094a8d4e060ce4dff61e8b700fb94962d3b080912e44b1fcd461b25d33","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-13T17:27:38.389Z","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":"2026-11-13T17:27:37.861Z","evidence_url":null,"receipt_uuid":"b3d7fed5-27ca-4e3f-9382-d9dfc242f41f","output_sha256":"sha256:25b868100d506085f8d29c6c79e673424858dcff4b5e1ce0efdaa4a8eba67ce0","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-13T17:27:37.861Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:25b868100d506085f8d29c6c79e673424858dcff4b5e1ce0efdaa4a8eba67ce0\",\"receipt_uuid\":\"b3d7fed5-27ca-4e3f-9382-d9dfc242f41f\",\"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":"2026-11-13T17:27:37.861Z","detail":"The receipt store reports 2026-11-13T17:27:37.861Z; 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.
