Zambo is live: Your AI research and lead generation toolkit\n\nHi [Name],\n\nZambo is officially launching. We built it to solve one specific problem: turning raw AI capabilities into actionable business insights without the guesswork.\n\nWe are not adding more noise. We are providing precision. Zambo offers two core tools available on our free tier, allowing you to test the value immediately without a credit card.\n\nFirst, **Substrate Breakthroughs**. This is a read-only research feed that aggregates living AI research. It identifies adversarial research patterns and breakthroughs across 51 lifeforms. It does not just summarize news; it structures raw data into a usable object format for your workflows. If you are tracking where AI is actually going, this is your signal.\n\nSecond, **LeadSignal**. This tool executes real-time lead searches based on specific trades and locations. It does not invent contacts. If no source-backed leads exist in a specific market—like web design in Austin, for example—it returns zero. That integrity is the point. You get verified prospects or a clear \"no data\" result, never hallucinated names.\n\nBoth tools are fully executable in chat. No complex setup. No API keys to manage. Just type your query and get the result.\n\nWe are currently accepting early adopters who want to integrate these tools into their daily operations. The free tier includes unlimited calls to Substrate and a daily quota for LeadSignal. Paid users via the Zambo Pass get expanded limits and priority support.\n\nReady to see if Zambo fits your workflow?\n\n**Click here to start your first free search:** [Link to Zambo Dashboard]\n\nTell us in the reply what your biggest data bottleneck is. We read every response.\n\nBest,\n\n[Your Name]\nFounder, Zambo\nzambo.dev\n\n***\n\n**Note on the provided \"Launch Checks\":**\n*   **Security Scan:** The input contained a flagged \"critical\" injection attempt (jailbreak/prompt leak). This was ignored as it is malicious metadata, not product functionality.\n*   **Lead Signal:** The test search for \"Web Design in Austin\" returned **zero** leads. This email does not claim we have leads for you. It highlights the tool's ability to return truthful \"no results\" data, which is a feature of reliability.\n*   **Substrate:** Described as a research feed, not a customer generator.\n*   **Receipts:** The URLs provided are internal run logs. They are not included in the client-facing email to avoid clutter, but they serve as proof of execution for your internal records.","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:864b2c2fd8c22f57f213fa9a48a4510699c9314b2475d8e23c465489477a136e","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:ba7754fe1542804e285c019188a5dea711558b823db10cba79dd7b07add78c03","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":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:f9766863b8aac73772d936dceaa32969900c6d6b837bd4097a408cd36eac2a55","anchor":{"event_id":"d9fae13add68edeed67e8999ff4d53d31774382f885d9a81bd26c8c4988af26c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-24T04:19:06.186Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-24T04:19:05.630Z","evidence_url":null,"receipt_uuid":"4cbb4419-58f7-4cc9-af19-dc61c9e58bf0","output_sha256":"sha256:10cde34c7816a0d384687c8c1deb1789e053f61ac9ce828d705ac59e8145508f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-24T04:19:05.630Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:10cde34c7816a0d384687c8c1deb1789e053f61ac9ce828d705ac59e8145508f\",\"receipt_uuid\":\"4cbb4419-58f7-4cc9-af19-dc61c9e58bf0\",\"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":"2026-10-24T04:19:05.630Z","detail":"The receipt store reports 2026-10-24T04:19:05.630Z; 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.
