What are the critical drivers of the founders for "Intention to Internationalise"?

This study examines the founder-level drivers of startups’ intention to internationalize. Using a
four-stage mixed-methods design—literature review, expert interviews, survey-based structural
equation modeling (N = 105), and qualitative validation—we develop and refine a model
grounded in the Theory of Planned Behavior. The final model identifies three significant
predictors of internationalization intention: ambition and mindset, knowledge of the foreign
market, and first-mover advantage, with “ambition and mindset” exerting the strongest influence.
Conversely, foreign-market networks and partner support show limited relevance at the intention
stage, suggesting their greater importance during the transition from intention to action. The
findings advance founder-centric theorizing in early internationalization and offer actionable
insights for policymakers, accelerators, and investors.
