Zambo is live: Real leads, zero fabrication**\n\nHi [Name],\n\nThe noise about AI lead generation is drowning out the signal. Most tools promise magic; they deliver guesses. Zambo is different. We built it to stop the guessing game.\n\nZambo is now available for public launch. It targets specific trades in specific US cities. You input a trade and a location; the system scans public, source-backed data. It returns qualified prospects. It does not scrape private PII. It does not invent names. If the data isn’t there, the tool says so.\n\nWe just ran a test for \"Web Design\" in Austin, TX. The result? Zero leads.\n\nMost competitors would have hallucinated five fake contacts to look helpful. Zambo returned an empty list. That is the feature. We prioritize accuracy over volume. A receipt proves the bytes saved, not the correctness of the lead. But we verify source backing before any lead appears.\n\nThis matters because your time is not a test bed for AI hallucinations. You need to know if a prospect exists before you spend a minute on outreach. Zambo gives you that binary answer.\n\nWe currently support 24 trades. The free tier allows three searches per day per IP. No auth required. No credit card.\n\nTry it yourself. Pick a trade you know is oversaturated. Pick a city. See if the tool finds real, source-backed prospects. If it finds nothing, you saved time. If it finds something, you have a verified starting point.\n\nThe link is below. It’s a direct run receipt from our internal test.\n\n[Link: https://zambo.dev/today/k/ir9ZumbZrVHYU-QfZLCRkmJWW7eaNFLgU4kls44HcISjjpz0Eg2mDzJMCkWz19jPh9l8Es--lliSV7t_IZpFbb39MptfReKR3uX8_aKbEFUOf6GpzbCl0IbmB8ob]\n\nStop paying for fake data.
