The CRM is one Lego piece. Here's the rest.

A modern GTM stack runs 12 to 30 tools across six layers. The CRM sits in the middle, but the action happens above and around it. Here's what real teams are running in 2026, and why pieces swap fast.

The six layers

1. Signal & data: ZoomInfo, 6sense, Common Room, Demandbase.
2. Orchestration & enrichment: Clay, n8n, Workato, Zapier.
3. System of record (CRM): Salesforce, HubSpot, Attio, Microsoft Dynamics.
4. Engagement: Outreach, Salesloft, Apollo, Smartlead.
5. Conversation & revenue intelligence: Gong, Clari, Fireflies, Avoma.
6. Attribution and analytics: HockeyStack, Snowflake, dbt.

Four real stacks

• Rippling — ~31 GTM tools. Salesforce + heavy custom orchestration above it.
• Vercel — ~28 tools. HubSpot + product-event-driven signal layer.
• ElevenLabs — Clay-centric stack. HubSpot as system of record, Clay as system of action.
• SMB B2B SaaS (~$3M ARR) — 12 tools. HubSpot/Pipedrive at the core; Apollo, Smartlead, Cal.com, Gong, light Clay.

Three principles when picking a CRM

1. Budget for the stack, not just the CRM.
2. Optimize for orchestration, not features.
3. Expect to swap pieces every 12 to 24 months.
