We propose that internal and external team learning processes transform the effects of founder(s)' entrepreneurial leadership into NVTs' team growth and performance in terms of effectiveness and agility. Using a sample of 78 NVTs in South Korea, the findings largely supported our proposed model. Specifically, internal team learning mediated the effects of the founder(s)' entrepreneurial leadership on team growth and team effectiveness. On the other hand, external team learning mediated the effect of the founder(s)' entrepreneurial leadership on team agility.39en©2025 The authorsEntrepreneurial leadershipExternal team learningInternal team learningNew venture teamTeam agilityTeam effectivenessTeam growth2025-06-2810.1177/10464964251343212105010347974
