Someone who comments on a competitor’s LinkedIn post is telling you they care about the problem you solve. Find those people, get their work emails, filter to your ICP, and reach out while the topic is fresh.

Watch It in Action

The Play

1

Identify competitor content

Find LinkedIn posts from competitor company pages, executives, and industry influencers that discuss problems your product solves. Focus on posts with high engagement (50+ reactions).
2

Extract engagers

Pull everyone who liked, commented on, or shared those posts.
3

Enrich contacts

Run the engager list through Deepline’s waterfall enrichment to get verified work emails, current job titles, company info, and LinkedIn profiles.
4

Score and filter

Filter to your ICP: target titles (VP Sales, Head of RevOps, GTM Engineer), company size, industry. Score by engagement depth — commenters > likers.
5

Route to sequences

Push qualified leads into your outreach tool with personalized context: the specific post they engaged with and what they said.

How It Works Under the Hood

  1. Apify LinkedIn scraper extracts post engagers (likes, comments, shares)
  2. Crustdata or LinkedIn enrichment resolves full profiles from engagement data
  3. Email waterfall (Dropleads → Hunter → LeadMagic → others) finds verified work emails
  4. AI scoring filters to ICP and ranks by engagement signal strength

Scoring Framework

What to Expect

Results vary by competitor post engagement volume and your ICP filters. A high-engagement post (100+ reactions) yields more raw engagers; tight ICP filters reduce the final list but improve quality.

Cost Estimate

  • LinkedIn scraping: ~$1-10 per 1,000 profiles via Apify (varies by actor and data depth)
  • Email waterfall: ~0.3 credits per contact (waterfall stops at first match)
  • Total depends on post engagement volume and enrichment hit rate
Reference the specific post in your outreach. “Saw your comment on [topic]” beats a generic pitch because it’s true.

Variations

  • Influencer audience mining — Target posts from industry thought leaders, not just competitors
  • Event attendee enrichment — Same pattern but with conference/webinar attendee lists
  • Community member targeting — Extract active members from Slack communities or Discord servers
