Your LinkedIn commenters are your warmest pipeline.

Here's a strange thing companies do every day: spend hours crafting a LinkedIn post, watch fifteen people comment on it, and reply to none of them. Then they open Sales Navigator to hunt for cold prospects who've never heard of them.

A commenter is not an engagement metric. A commenter is a hand raised. They saw your point of view, felt strongly enough to respond publicly, and attached their name and job title to it. That's more buying signal than any intent-data tool will ever sell you — and it's sitting in your notifications tab, free.

The 24-hour window

Engagement decays like radioactive material. Reply within a few hours and you have a conversation; reply next week and you're a stranger again. The system is simple, but it has to be a system — not a thing you do when you remember:

1. Reply to every substantive comment — with a real response that extends the thought, not "Thanks for sharing!"
2. Sort commenters against your ICP. A VP at a target account gets different treatment than a peer or a job-seeker. Both get a reply; only one gets step three.
3. Move ICP-fit commenters to the DM — referencing what they actually said. Not a pitch. A continuation.
4. Log them. Repeat commenters are telling you something. Three comments over a month is a warm lead behaving exactly like a warm lead.

Why nobody does this

Because it's unglamorous, daily, and invisible in a monthly report that only tracks impressions. Founders don't have the time. Marketing teams don't have the mandate. So the warmest names in the pipeline scroll past, week after week.

This is precisely the kind of work that belongs in a system: someone monitoring every comment, replying in your voice within hours, and starting DM conversations with the ones who fit. When we run engagement for clients, this loop — comment, reply, qualify, DM — is where the "where did this lead come from?" stories start.
