Your first 5 leads are ready (no setup required)\n\nWe built Zambo Stack to solve one specific problem: finding qualified local service leads without the manual scouring of Google Maps.\n\nYou ask for a trade and a city. We return five source-backed prospects with contact info in under 60 seconds. No API keys. No complex setup. Just immediate results.\n\nWe are launching today. The system supports 24 trades across any US city. We ran a test for roofers in Phoenix, and the pipeline delivered exactly what it promised: relevant, verified data points you can use immediately.\n\n**The Core Benefit**\nStop guessing who might need your services. Start with a list of businesses that fit your criteria, backed by public source data. This is not a generic database dump; it is targeted research designed for contractors and local service operators who need revenue, not just data.\n\n**Why This Works Now**\nMost lead tools require you to build a pipeline before you get value. Zambo Stack flips that. You get the output first. If the leads are good, you stay. If they aren’t, you walk away. We are confident in the data integrity because we show you the source for every entry.\n\n**Next Step**\nWe are opening access to the first cohort. There is a free first call available per tool per UTC day. This allows you to test the specific trade and city you serve most.\n\nClick here to run your first search: [Insert Link]\n\nIf the first five leads don’t save you time, you owe us nothing. If they do, you have a new engine for your top-of-funnel.\n\nLet’s see what’s in your city today.\n\nBest,\n\n[Your Name]\nFounder, Zambo Stack\n[Website URL]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:254942d6e61e017e7643dff62cea194fc453442b4f82540914c84ce8632dc861","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":"4.1.4","scope":"public"},"caller":{"type":"session","id":"sha256:85a48d2249bca8803d47938c415afa87892bba753583cffb43847c96dedf91cb","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":"sha256:6b9d0d1d12c5b1f686ff376bed194752a7c40d00db04ac2e176a58eff8b58519","anchor":{"event_id":"f06b34337c317fb79f119fccdf3ba9868482cfb77e5e21054db72777a8fb4f38","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-14T02:52:29.462Z","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":"2026-11-14T02:52:28.700Z","evidence_url":null,"receipt_uuid":"2566659a-635c-4db5-9e32-8b92e36ec41e","output_sha256":"sha256:58ab57f4abcd5edee153e894f02dcec01c2e0390a3fa66298d70265967831743","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-14T02:52:28.700Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:58ab57f4abcd5edee153e894f02dcec01c2e0390a3fa66298d70265967831743\",\"receipt_uuid\":\"2566659a-635c-4db5-9e32-8b92e36ec41e\",\"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":"2026-11-14T02:52:28.700Z","detail":"The receipt store reports 2026-11-14T02:52:28.700Z; 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.
