What would a modern AI-powered sales stack look like if rebuilt from scratch today?

A modern AI sales stack should be built around three core pillars: data enrichment automation, AI-powered personalization, and multi-channel orchestration. Start with Clay as your enrichment backbone, cascading through Apollo → ZoomInfo → Cognism for contacts and Clearbit → 6sense for company data. Add ChatGPT API integration for research summarization and personalization. For execution, use Smartlead or Instantly for sequence deployment with proper email verification through LeadMagic or Prospeo. Complete the stack with HubSpot as your CRM, Attention or Sybill for call intelligence, and ensure all tools are interconnected for seamless data flow. Budget $500-800/month for individual contributors or $2K+ for team operations. Focus on quick wins and ROI assessment when implementing - your first two projects will determine overall success.
