Cornersight finds the people who react to or comment on your competitors' LinkedIn posts, flags the ones that match your ideal customer, and sends them to HeyReach or your own tools.

Why look at who engages with a competitor's posts?

People who engage with a competitor's posts already know the category. A comment often tells you what the person cares about.

How do I see who engages with a competitor's post by hand?

You can do it by hand, one post at a time:

  1. Open the competitor's post.
  2. Read through the people who reacted and commented.
  3. Copy the names you want into a sheet.
  4. Look up each person's role and company yourself.

Doing it by hand works for a few posts a week. It doesn't scale to several competitors, and you have to repeat it for every new post.

How does Cornersight track competitor engagement?

Cornersight tracks the LinkedIn sources you add and captures the people who engage. You can track:

  • a competitor's company page
  • the profiles of their founders and staff
  • a single post
  • a keyword search

Add the founders as well as the company page. Cornersight checks each tracked profile and company page daily for new posts.

Are all the people who engage real buyers?

No. Many people who engage with a competitor's post are not buyers. Set an ICP filter on each source, and Cornersight checks each lead against it. Each lead then shows whether it matches your ICP.

Precision Outbound tracks Gist's competitors and their leaders, plus other LinkedIn pages, people and keyword searches. In two weeks, 2,035 likes and comments came down to 15 real buyers. Read how they filter →

How do I go from an engager to a conversation?

Send your ICP leads to the outreach tool you already use:

  • Push leads to HeyReach or PlusVibe.
  • Send them by webhook to Clay, n8n or any URL.
  • Download a CSV from the Leads page.

Does Cornersight give emails?

We don't sell emails. Connect your own email finder (for example LeadMagic) and Cornersight finds emails for your ICP leads with your own credits.

What does it cost to track competitors?

Cornersight costs 1 credit per lead.
