The entrepreneurial journey is often experienced as an emotional rollercoaster, but we know very little about how entrepreneurs can ride it most effectively to increase their ventures' chances of survival. We investigate how entrepreneurs' habitual use of cognitive reappraisal and expressive suppression – two well-established types of emotion regulation – impact on the likelihood of their venture surviving. Drawing on a sample of 183 technology ventures, we find that both regulation types are generally associated with a lower survival likelihood, but that these effects depend on the venture's performance. Our study contributes to the literatures on emotions and new venture survival in entrepreneurship and to the emotion regulation literature.
