LeadMarina

LeadMarina finds local businesses in any US city by niche and turns them into verified sales leads. Search "plumbers in Tampa" and each lead comes back with up to three emails, each SMTP-checked and labelled safe, risky or invalid, plus up to three phone numbers with line type (mobile, landline, VoIP or toll-free) and carrier. Owner names come from public records or the business's own website where found, along with named contacts and their titles where the site lists them.

Send leads to Google Sheets, Close or GoHighLevel. Those exports update existing records instead of creating duplicates, and searches can repeat on a schedule. You can also download CSV, Excel or JSON. Developers get a REST API. AI users can connect the remote MCP server to Claude, ChatGPT, Cursor or any MCP client, with nothing to install.

The free plan includes 100 verified leads and full API access, with no credit card required.
