In Nigeria’s emerging markets, ventures struggle with volatile economic conditions, inadequate infrastructure and limited access to finance. Despite these challenges, some enterprises achieve exceptional performance by carefully aligning their resources with attractive market opportunities. This study explores how the fit between entrepreneurial resources (tangible and intangible) and opportunities influences venture performance. Using a resource–opportunity fit model grounded in the resource‑based view (RBV) and opportunity‑based entrepreneurship theory, the paper synthesizes recent literature, surveys Nigerian entrepreneurs, analyses case evidence and proposes policy recommendations. Findings reveal that intangible assets (such as knowledge, networks and employees’ competencies) significantly enhance competitive advantage and organisational image[1], while opportunity recognition competence strongly predicts firm performance[2]. The study recommends strategic asset audits, opportunity mapping and supportive policy frameworks to foster sustainable enterprise growth.
