Background: Founders hold a powerful position that can shape the future and direction of their new ventures, especially in the early stages of venture development. Prior work experiences are known to be influential for future growth, but the relationship between founders' prior work experiences and their growth intentions is poorly understood.  Purpose: The study aims to contribute to the existing literature by furthering the awareness and understanding of how founders are using their prior work experiences when shaping and evaluating their growth intentions. The study answers the research question:  How do founders' prior work experiences influence growth intentions in the early stages of venture development?  Method: Our method is based on qualitative research and adapts an explanatory purpose to capture the process between prior work experiences and growth intentions and elaborate the understanding of how growth intentions are created in the early stage of the ventures' development. Through a case study with semi-structured interviews, we have interviewed nine new venture founders in the tech sector, which have been the ground for our empirics. The analysis of data was conducted in three steps, namely empirical analysis, retroduction, and corroboration.  Conclusion: Our study advances the explanation of how founders' prior work experiences shape how they manage their ventures' internal environments, which impact their growth intentions. By conducting a conceptual model, we explained how building social working environment, structuring people and practices, and implementing routines manifest as mechanisms in the process between prior experiences and growth.
