Zambo is live: AI lead gen for local trades\n\nHi [Name],\n\nZambo is officially launched. We built this to solve one specific problem: finding qualified, source-backed leads for contractors and local service businesses in under 60 seconds.\n\nNo more guessing. No more scraping dead data.\n\nZambo supports 24 trades across any US city. You provide the trade and location; we return five qualified prospects with contact info. The system prioritizes accuracy over volume. If we cannot verify a source-backed prospect, we do not send a lead. A receipt confirms the data integrity of every run, ensuring you see exactly what was saved and verified.\n\nWe know the market is noisy. Most AI tools promise \"synergy\" and \"game-changing\" results while delivering generic lists. Zambo is different. It is a precision tool for operators who need real conversations, not just data points.\n\nWe are currently running live audits and lead generation tests to refine the engine. We have not yet closed sales, and we are not claiming to have fixed every edge case in the industry. We are focusing on delivering consistent, verifiable results for the first batch of users.\n\nI am looking for five specific types of businesses to stress-test the platform. We need feedback from people who know their local market intimately.\n\n**Specific CTA:**\nIf you run a roofing, HVAC, or plumbing business in Phoenix, Austin, or Denver, reply to this email with your trade and city. I will run a free LeadSignal query for you. You will receive the raw output and the verification receipt. No strings attached. No sales pitch. Just data.\n\nIf the results are not useful, delete the email. If they are, let’s talk about how to integrate this into your daily workflow.\n\nBest,\n\n[Your Name]\nFounder, Zambo\nzambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e4ce0ae43c8f1ec3cd41ebc96e41aa445cdeaaf5fb9ed03b5d839e9dba95bdfa","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":"sha256:4984192f4e54c79fce001ee456b0eeaf18d276d125bd773f4f7af723fc1d8b90","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:fc4d401623c9e32a4cec54d49bcb4b096dcd0d2312cb3670e017e5764715958b","anchor":{"event_id":"5a34659c5896c26028801241eefa27bf21dba01e7938a31f907586b7e77191f8","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-13T04:41:15.246Z","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":"2026-11-13T04:41:14.635Z","evidence_url":null,"receipt_uuid":"39af7c8c-e6d3-454e-869f-655d916f3f25","output_sha256":"sha256:7b1b5b16de108d459586c17d79292ef469548a18e2682cea5373baf24d7cb770","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-13T04:41:14.635Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:7b1b5b16de108d459586c17d79292ef469548a18e2682cea5373baf24d7cb770\",\"receipt_uuid\":\"39af7c8c-e6d3-454e-869f-655d916f3f25\",\"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":"2026-11-13T04:41:14.635Z","detail":"The receipt store reports 2026-11-13T04:41:14.635Z; 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.
