In this guide, we’ll show you how to use TheirStack to update one periodically with companies and leads potentially interested in your product or solution.

Introduction

LinkedIn lets you use company and contact targeting to build audience segments based on lists of companies and organizations.

This means you can show ads on LinkedIn to people who work at the companies you’re interested in selling to, and even target the people inside those companies directly if you know who they are.

To do it, LinkedIn lets you upload a CSV with companies or accounts, as described in the link below.

They also provide an API that lets you upload the CSV programmatically. All that’s left is building that CSV dynamically, and that’s where TheirStack comes into play.

Basic steps

You’ll need to

• Make a job or company search on TheirStack
• Build a CSV file with the columns required by LinkedIn
• Upload it to LinkedIn
• Tell LinkedIn to which audience it has to be attached

We’ll use Make.com in this guide, but it can be done with code as well.

Requirements

• A TheirStack account with API access. Go to app.theirstack.com/signup if you don’t have one yet. Note that API access is only available on some paid plans.
• A [Make.com (formerly Integromat)](https://xoel.notion.site/Make-com-formerly-Integromat-64ed4fb057774d3dbbec9299d833dd17) account. Check that link to learn how to use your TheirStack account on Make.
