Agencies can turn the people who engage with each client's LinkedIn posts into leads for that client.

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

How do agencies use LinkedIn engagement for outreach?

Agencies track the LinkedIn accounts that matter to each client, then reach out to the people who engage. For each client you can track:

  • the client's own profiles and company page
  • their competitors' company pages and founders
  • single posts
  • keyword searches about the client's market

Cornersight captures the people who engage, with job title, company, country, company details, the post, and the comment if they left one.

Automight runs outbound and automation campaigns for clients. For one client, they pulled everyone engaging with the founder's and co-founder's posts. That one scrape got 40 positive replies and 20 meetings. Read Automight's story →

How do I keep each client's leads apart?

Keep each client's leads apart by giving each source its own webhook. Point one client's sources at that client's URL, and another client's sources at theirs. Several sources can also share one URL. Each lead's trackedProfile field says which source it came from.

Can I check leads against each client's ICP?

Yes. Set an ICP filter on each source, and Cornersight checks each lead against it. Each client can have a different ideal customer. On the webhook you choose all leads, or ICP matches only.

Do I need a LinkedIn login?

No. Cornersight finds who engaged without your LinkedIn login or cookies. Nothing runs on your account. Your clients never share their LinkedIn logins either.

Where do the leads go?

Leads go to the outreach tools you already run for clients:

  • HeyReach or PlusVibe, by push
  • Clay, n8n or any URL, by webhook
  • the REST API, the MCP server or the CLI
  • a CSV file from the "Export CSV" button on the Leads page

Can I report on who engages with a client's posts?

You can show a client who engaged with their posts. Track the client's profile or company page, and export the leads to a CSV. The file has 22 columns, including name, job title, company, country, company details, post and comment.

Do leads come with 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 for an agency?

Cornersight costs 1 credit per lead. Pick the plan that covers all your clients' leads. Paid plans have no limit on how many sources you track.
