The Problem
Pipeline ran on referrals only, in an ultra-niche market of 500 to 800 real Tier 1 targets.
The Build
Six-layer system: ICP tiers, Clay enrichment, AI scoring, 6 buying signals, email + LinkedIn, full handoff.
The Outcome
Live in 27 days. 12 campaigns, 1.6% bounce, and a system the client's team now runs on its own.
Context
The client
A fast-growing US cybersecurity consultancy specializing in penetration testing, embedded security, firmware reverse engineering, and hardware lab testing. Capabilities that fewer than a handful of firms worldwide can match, with a client roster of major enterprise technology companies.
Despite world-class technical work, they had no systematic outbound function. Pipeline relied entirely on referrals and inbound. They needed a full outbound engine built from scratch, fast, to open new enterprise conversations at scale.
Constraints
Why this was hard
Ultra-niche ICP.
Companies building physical products with embedded software: vehicles, medical devices, drones, satellites, IoT. The realistic Tier 1 universe is 500 to 800 companies, total.
The hardest audience in outbound.
CISOs and security leaders receive sophisticated outreach daily and evaluate technical depth as a buying signal. Generic emails don't just underperform here, they burn credibility.
Multi-channel from day one.
Email and LinkedIn across multiple sender personas, launched in parallel, consistent messaging, no overlap.
Zero infrastructure.
No domains, no enrichment pipelines, no sequences, no DNC lists, no scoring. Everything built from scratch.
Architecture
The system
One engine, six layers. A tiered target universe feeds a Clay enrichment engine, buying signals decide who gets contacted and with what message, and safety rails sit under everything before a single email leaves.

Fit
Who this is for
Technical firms with world-class delivery but no outbound.
If you win every deal you touch but rely on referrals to start conversations, the problem is not sales. It is pipeline generation.
Ultra-niche ICPs (500 to 1,000 addressable companies)
where signal-based campaigns that reference real buying triggers beat volume plays, because every prospect matters.
Teams that need the engine fast.
Not a 6-month hiring cycle: a production system with enrichment, scoring, signals, and multi-channel campaigns live in weeks.
