B2B sales are shifting from individual leads to Account-Based Experience (ABX) as complex purchases now involve committees of 10 to 23 stakeholders. Traditional strategies fail because they ignore the need for internal consensus. ABX uses AI to detect group intent through role density and research surges, allowing teams to orchestrate engagement across the entire buying group early in the process. Successful ABX requires role-specific content delivered via a "content supply chain." Success is measured by new metrics like Buying Group Coverage and Account Engagement Scores. By prioritizing committee orchestration, organizations can achieve up to 50% higher conversion rates and significantly faster pipeline velocity.
