Entrepreneurial ventures benefit from breaking out of structural localism to access external supports as they scale their businesses. However, there is limited theory development on how internationally scaling businesses access external supports. By adopting an entrepreneurial network perspective to study the support system for internationally scaling businesses located in Ireland, we identify an international support web accessed through network mechanisms that break out of structural localism. This study contributes to international entrepreneurship by elaborating on network mechanisms for scaling businesses, in contrast with early and rapidly internationalizing ventures and mature multinational enterprises. It also contributes to international connectivity research by detailing micro-processes for cross-border resource flows.
