Lean Intros: warm-intro pathfinder. Finds warm introduction paths from LinkedIn export files.

In simple English

This tool helps you find out who in your network knows your target clients or investors. You upload a CSV file of your contact's LinkedIn connections. You upload a list of the people you want to reach. The program matches them and shows who can make an introduction. It runs on your computer and keeps your data in a private file.

What it is

Lean Intros is a self-hosted (run on your own computer) Python (a programming language) application that matches contact lists against target prospect lists. It scores the likelihood of a real relationship based on shared work history and schools.

What it is good for

Founders and salespeople who want to find warm paths to target prospects using connection lists exported from their network's LinkedIn accounts, without paying for expensive enterprise introduction platforms.
