We introduce the concept of team entrepreneurial passion (TEP), a team-level construct representing the level of shared intense positive feelings for a collective and central team identity for new venture teams (NVTs). Additionally, we develop a dynamic theoretical model of (a) the processes by which TEP can emerge from different combinations of new venture team members' individual entrepreneurial passions; (b) the influence of TEP on team and individual member outcomes; and (c) the relative importance of TEP emergence and influence processes at different venture stages. Our model has theoretical and practical implications for scholarship concerning affective diversity, shared affect, collective identity, NVTs, and entrepreneurial passion.
