Prior research has studied the many aspects of entrepreneurial mindset employing multiple conceptualizations and alternative definitions. Little is known, however, about how organization sponsor initiated top-down entrepreneur support processes aimed at enhancing mindset and capacity to navigate the complex challenges posed by the multi-level entrepreneurial ecosystem effects of limited stakeholder alignment and sociocultural obstacles. Approaching entrepreneur mindset as an array of improvable elements, referred to as Mindset Assets, which span the sensing, acting, and adapting phases of entrepreneurship, this study employs a qualitative approach to examine an entrepreneurial accelerator designed to enhance these mindset assets by leveraging resources between entrepreneurs from a former communist country and California’s Silicon Valley. Using survey data and qualitative interviews from a cross-ecosystem mindset intervention program, this paper analyzes the program's impact on participants' mindsets, identifies key drivers of mindset improvements that facilitate action and adaptation, and evaluates its effectiveness in enhancing entrepreneurial capacity to navigate complex ecosystem challenges. Findings reveal that this type of cross-ecosystem mindset intervention provides distinct advantages not typically found in single-ecosystem programs, offering details and insights into how enhanced sensing mindset elements lead to improved action and adaptation capabilities. This research provides empirical evidence and theoretical expansion for the concept that an enhanced entrepreneurial mindset can effectively counteract the restrictive multi-level influences of limited stakeholder alignment and constrained sociocultural factors in a former-communist transition country.
