The most effective AI tools combine a CRM, a marketing automation platform, an ABM layer, and a content AI assistant with strong governance. For enterprise B2B, that typically means Salesforce or Microsoft Dynamics 365 plus Marketo Engage, HubSpot, or Pardot; add 6sense or Demandbase for account-based intent and orchestration, and use Adobe Experience Platform or Optimizely for personalization and testing. TSC's Chief Strategy Officer JJ La Pata notes that teams see the biggest lift when these tools share a unified account and contact model, so intent signals can trigger specific plays like “3 ads + 2 emails + 1 SDR task” within 7 days.
