VERDICT: BUILDBERG SCORE 74/100

An automated agent that monitors LinkedIn influencer posts, extracts engagers as warm leads, enriches their contact info via waterfall enrichment, and runs personalized cold email + LinkedIn DM outbound campaigns on autopilot.

01 THE IDEA

This system identifies target customers by treating LinkedIn post engagements (likes, comments) as buying-intent signals. The agent scrapes engagers from relevant influencer posts using Apify's LinkedIn APIs, then runs waterfall enrichment through tools like GetLeads.io, Apollo, and Origami to find verified emails and phone numbers. It then validates emails via MillionVerifier and sends outbound cold emails via Instantly using burner inbox infrastructure from Hypertide or InboxKit.

The agent also manages the reply inbox — answering questions, pushing leads toward booking demos, and scheduling follow-ups months later via calendar integrations like Cal.com. What differentiates this from generic cold outbound is the intent-signal layer: instead of blasting firmographic lists, you're targeting people who literally just raised their hand by engaging with relevant content. This is a productizable SaaS or agency offering that could be sold to B2B sales teams, startups, and growth-stage companies.

03 THE VERDICT

This is a genuinely differentiated take on outbound — using engagement signals as intent data is smarter than firmographic targeting and the technical stack is accessible today. Clay is the closest competitor but is expensive and not purpose-built for this social-signal workflow. A focused SaaS or done-for-you agency around this specific motion could achieve strong PMF quickly with B2B startups. The main risk is LinkedIn's continued crackdown on scraping, which creates platform dependency.
