Purpose: The COVID-19 crisis has significantly affected entrepreneurial ventures, where knowledge resources are limited and contextual uncertainty is heightened. This paper aims to identify if and how interorganizational learning (IOL) may assist entrepreneurial ventures adapt, survive and grow in a crisis. Design/methodology/approach: The following research question is asked: How may responding to the adversity induced by the COVID-19 pandemic affect IOL between entrepreneurial ventures? Four hypotheses were developed to carry out a quantitative study of 228 knowledge-based entrepreneurial ventures in Norway. Findings: The results illustrate how different combinations of adversity from COVID-19 and the active responses conducted by entrepreneurial ventures influence IOL. Four clusters representing different behaviors are developed accordingly as follows: "collaborators", "supporters", "responders" and "victims." The findings provide empirical support for the importance of engaging in interactive and collaborative activities for IOL. Research limitations/implications: The findings can help in understanding how COVID-19 influences IOL between entrepreneurial ventures. Policymakers may use these findings to promote organizational continuity in entrepreneurial ventures by creating and nurturing support systems that promote IOL during a crisis. Originality/value: Studying a contemporary and critical situation -- the COVID-19 pandemic -- the present paper provides an empirical study of the antecedents to IOL, adding to the currently scarce body of research on IOL in and between entrepreneurial ventures.
