Series C is the migration tier. The HubSpot/Smartlead/Apollo seed core gives way to enterprise-grade infrastructure: Outreach for compliant multi-channel sequencing, ZoomInfo for fortune-1000 contact data, Gong for call intelligence and revenue-ops feedback loops. Clay stays as the orchestration glue — it handles the long tail of enrichment and routing logic that the heavyweight platforms don’t cover well.
