ICP Architecture
Core Premise: Vague targeting destroys demand economics. Precision creates efficiency. ICP Architecture builds targeting that reaches buyers, not browsers.
The Precision Imperative
| Targeting | Reach | Conversion | CAC |
|---|---|---|---|
| Broad | 1,000,000 | 0.1% | $8,000 |
| Moderate | 200,000 | 0.5% | $3,500 |
| Precise | 50,000 | 2.0% | $1,200 |
Precise targeting reaches fewer people but converts dramatically more efficiently.
The Five Dimensions of ICP
Dimension 1: Firmographic
Company-level attributes: size, industry, funding stage, technology stack.
Vague: "Mid-size companies" Precise: "SaaS companies, $20M-$100M revenue, Series B-D funded, using Salesforce"
Dimension 2: Demographic
Individual attributes: title, department, seniority.
Vague: "Marketing leaders" Precise: "VP or Director of Demand Generation, 5+ years in B2B SaaS, in role 6-24 months"
Dimension 3: Psychographic
Mindset and priorities. What they discuss publicly, content they consume, events they attend.
Dimension 4: Behavioral
Actions indicating intent: website visits, content engagement, product usage, third-party intent data.
Dimension 5: Temporal
Timing signals: funding rounds, new executives, job postings, contract renewals.
The List Test
Can a researcher build a list of 100 targets using only your ICP documentation without asking clarifying questions?
If yes, your ICP is specific enough. If no, refine until they can.
