Most Martech stacks accumulate rather than get designed. A tool is added when a problem appears, another when a new hire joins. The result is redundancy, poor integration, and spend that exceeds its commercial return. This framework defines what you actually need — and when.
Tier 3 — Scale Layer
Advanced Intelligence & Automation
Adds compounding operational advantage when pipeline volume and team size justify the investment. Do not add before you can fully operate what is below.
ABM Platform
AI Research & Content (Maaran.ai)
Advanced Attribution (W-shaped)
Conversation Intelligence
Predictive Scoring
Revenue Operations Platform
When to add
Series B+
£80K–£200K+ / year
Tier 2 — Intelligence Layer
Intent, Analytics & Attribution
Multiplies the value of demand generation spend by enabling targeting and measurement not possible with the foundation layer alone.
Intent Data (Bombora / G2)
Multi-touch Attribution
BI / Analytics Platform
LinkedIn Campaign Manager
Sales Intelligence (Apollo / ZoomInfo)
When to add
Series A–B
£30K–£80K / year
Tier 1 — Foundation Layer
CRM, Automation & Website
The infrastructure every commercial motion depends on. Must be configured correctly before anything else is added. A well-configured basic stack outperforms an improperly configured enterprise stack every time.
CRM (HubSpot / Salesforce)
Marketing Automation (native to CRM)
Website with conversion tracking
Email delivery platform
Basic reporting dashboard
When to add
Seed – Series A
£15K–£30K / year
The single most common mistake: adding Tier 2 and Tier 3 tools before the Tier 1 foundation is properly configured. Intent data pointing at accounts in a misconfigured CRM produces no commercial intelligence. The sequence matters as much as the selection.
