Abstract : Scaling marketing organizations in business-to-business (B2B) environments requires a systematic integration of strategic, structural, and technological capabilities. This study investigates the enterprise growth strategies that enable scalable marketing performance across mid-sized and large B2B firms. Adopting a multi-method research design, the study integrates survey data from 162 firms, executive interviews, hierarchical regression analysis, structural equation modeling, and cluster-based segmentation. The findings reveal that Strategic Alignment and Organizational Agility are the strongest predictors of Marketing Scalability Performance (MSP), while Marketing Technology Integration and Data Analytics Capability significantly enhance revenue growth when supported by Process Standardization and Cross-Functional Integration. Mediation analysis confirms that standardized execution frameworks and integrated collaboration mechanisms translate strategic intent into measurable scalability outcomes. Cluster analysis identifies four scalability archetypes—Emerging, Structured, Technology-Driven, and Fully Integrated—with Fully Integrated firms demonstrating the highest revenue growth and performance maturity. The results underscore that scalable B2B marketing is not driven by isolated digital investments but by integrated growth architectures aligning enterprise strategy, technology infrastructure, governance mechanisms, and performance analytics. The study contributes to enterprise growth literature by conceptualizing marketing scalability as a multidimensional organizational capability and provides managerial insights for designing high-performance marketing systems in complex B2B markets.
