You input a trade and a city, and the system returns five qualified prospects with contact information in under 60 seconds. It currently supports 24 trades across any US city.\n\nThere is no signup process. No API keys. No authentication hurdles. The tool runs on a free tier that allows three searches per day per IP.\n\nWe are launching now.\n\nI am writing to you because your work in [Recipient's Field/Industry] aligns directly with the use case. I am not asking for a sale. I am asking for your eyes on the output quality.\n\nTry the tool. Pick a trade and a city. See if the data feels useful to you.\n\n[Link to Zambo]\n\nPlease note: A successful search confirms the tool is active and returning data. It does not guarantee the accuracy of every single lead.
