GA-6: GTM Stack Design

GA-6 · GTM Architect · 150 XP · ~20 min

There is no universal “best GTM stack.” The right stack depends on company stage, team size, ICP complexity, and motion type. A 10-person company with one founder doing outbound needs different tools than a 200-person company with a 20-rep SDR team. This module teaches you to design stacks that match context — and to know when a stack needs to evolve.

Stack by Stage

Seed / Pre-Seed (1–10 employees, founder-led GTM)

Core needs: Find leads fast, validate messaging, book meetings without overhead.

Category	Tool Options	Why
CRM	HubSpot Free / Airtable	Low cost, easy setup
Contact source	Apollo.io	All-in-one: find + enrich + sequence
Email infrastructure	Google Workspace + Instantly	Affordable, reliable
Data enrichment	Bitscale	AI-powered enrichment without enterprise pricing
Analytics	Sheets / Notion	Low overhead

Total monthly cost: $200–500/month

Series A (11–50 employees, first sales team)

Core needs: Scale what’s working, build process, start measuring attribution.

Category	Tool Options	Why
CRM	HubSpot Pro or Salesforce Starter	Reporting + pipeline visibility
Contact source	Apollo + LinkedIn Sales Nav	Broader ICP coverage
Sequencer	Apollo Sequences or Instantly Pro	Volume + reply tracking
Email infrastructure	Multiple warmup domains	3–5 sending domains
Data enrichment	Bitscale + Clearbit	Deeper enrichment per contact
Signal	LinkedIn alerts + Crunchbase	Basic signal detection
Analytics	HubSpot reports or Looker	Pipeline attribution starting

Total monthly cost: $2,000–5,000/month

Series B (51–200 employees, scaling SDR team)

Core needs: Efficiency at scale, full attribution, tech stack optimization.

Category	Tool Options	Why
CRM	Salesforce Enterprise	Full attribution, complex routing
Contact source	ZoomInfo + LinkedIn Sales Nav	Largest coverage
Sequencer	Outreach or Salesloft	Advanced analytics, AI features
Email infrastructure	Warmy + 10+ sending domains	High-volume sending
Data enrichment	Bitscale + enrichment waterfall	Maximum coverage + quality
Signal	Bombora + Crunchbase + job board monitoring	Full signal coverage
Intent	6sense or Demandbase	Account-based intent
Analytics	Salesforce + Tableau or Looker	Full funnel attribution
Automation	Zapier / n8n for integrations	Workflow automation

Total monthly cost: $15,000–40,000/month

Stack Evaluation Framework

When evaluating any tool for your GTM stack, score it on six dimensions:

Evaluate this tool for our GTM stack:

Tool name: {{tool_name}}
Use case: {{intended_use_case}}
Company stage: {{company_stage}}

Score 1-5 on each dimension:
1. Coverage: Does it cover our ICP well?
2. Accuracy: Is the data/output reliable?
3. Integration: Does it connect cleanly to our existing stack?
4. Cost efficiency: Value relative to price at our volume?
5. Time to value: How quickly can we operationalize it?
6. Scalability: Will it still work 2x our current volume?

Calculate total score (max 30). Recommend: adopt / trial / defer / reject.

Return as JSON.

Stack Evolution Triggers

Know when your stack needs to change:

Signal	Implication
Bounce rates creeping above 3%	Email infrastructure not scaling with volume
CRM data quality degrading	Enrichment source coverage has gaps
SDR ramp time > 90 days	Process and tooling too complex for new hires
Attribution gaps in the funnel	Analytics integration incomplete
3+ tools doing overlapping functions	Tech debt accumulating; consolidation needed
Sequencer not logging activity back to CRM	Integration broken; attribution blind

Run a quarterly stack review: for each tool, document utilization, actual cost, and whether you’d buy it again today.

Quick Check: What are the three company stages and their primary GTM stack needs? What six dimensions should you evaluate when selecting a tool? Name three signals that indicate your stack needs to evolve.

GA-6 Challenge: Design a GTM Stack (+150 XP)

Design a complete GTM stack for two different company stages (your choice of which two). Requirements:

Tool selection with rationale for each category (both stages)
Stack evaluation scoring for 3 specific tools using the 6-dimension framework
Cost estimate per stage
Migration plan: if a Series A company is moving to a Series B stack, what’s the transition sequence?
A 2-paragraph brief: what’s the most common stack mistake you see at each stage?
