<![CDATA[University academics possess substantial intellectual capital derived from knowledge, expertise, research capability, professional experience, reputation, and relational networks. However, the possession of intellectual capital does not automatically translate into economic value or financial resilience. Existing research has separately examined intellectual capital, academic engagement, academic entrepreneurship, multiple job holding, portfolio careers, career ecosystems, and financial well-being. These literature streams provide valuable but fragmented explanations of how academics create value beyond their primary institutional employment. This conceptual study aims to integrate these perspectives by proposing the Professional Income Ecosystem (PIE) framework. Using a theory-synthesis approach, the study conceptualizes PIE as a dynamic system through which knowledge professionals transform intellectual capital into economic value through competency monetization capability and a professionally coherent income portfolio, while maintaining professional–academic synergy. The framework further proposes that diversified and coherent professional activities may enhance professional financial resilience and simultaneously generate experiential knowledge, relational capital, reputation, and resources that reinforce the intellectual capital from which the ecosystem originated. Five theoretical propositions are developed. The principal contribution of PIE lies not in advocating multiple jobs or income streams, but in shifting the analytical focus from multiple job holding toward the strategic orchestration of intellectual capital across interconnected value-generating professional activities. The study provides a conceptual foundation for subsequent empirical validation, scale development, and comparative research across academic and other knowledge-intensive professions.]]>
