This study examines the relationship of the entrepreneur's personality to long-term venture survival. We measure survival in two ways: (1) the likelihood the venture will survive for at least 8 years and (2) the overall life span of the venture. The “Big Five” personality attributes—extraversion, emotional stability, agreeableness, conscientiousness, and openness to experience provide the measures of the entrepreneur's personality. As hypothesized, the entrepreneur's conscientiousness was positively related to long-term venture survival. Contrary to expectations, we found a negative relationship between the entrepreneur's openness and long-term venture survival. Extraversion, emotional stability, and agreeableness were unrelated to long-term venture survival
