What they did
The founder put together a local, MIT-licensed tool in under a day as a simple interface for Claude Code to handle repeatable sales work. Claude used Chrome to inspect LinkedIn, add context such as company structure and engagement clues, then graded leads against the team’s internal rules, partly inspired by Founding Sales. It also picked out the likely decision-makers before the remaining prospects were handed off for cold outreach.
How it went
After the tool cut roughly 90% of the noisy leads, the campaign brought in 10 booked demos in one week. The post does not share deeper funnel metrics or any other hard limits.
Tips
This works best when the criteria are specific and the lead list already has some enrichment. If the agent is going to send email, have it stop and ask before any message leaves your inbox.

Try it yourself with Claude Code

I have a list of enriched leads in [file or folder]. Review each lead against [my qualification criteria], remove obvious mismatches and noise, and score the rest from 1 to 10. Use available web and profile data to identify the right contact at each company and draft a short cold email for leads at or above [score threshold] that is aimed at booking a demo. Show me the ranked list and a few sample drafts first, then pause and ask for my approval before sending any email. Save the final list and drafts to [output location].

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
