Entrepreneurship literature has generally ignored the entrepreneur’s dark side. Individuals high on dark characteristics may have success, but leave a trial of interpersonal abuse and harm. Examining the relationship between founder levels of the dark triad, employee creativity and performance, support was found for the hypothesis that increases in employee tenure will weaken any benefits garnered by dark triad tactics. The results have significant implications for understanding the dark triad – employee performance link. Practically, the results may help investors identify and replace problem founders, reducing the likelihood of negative employee-related outcomes which may hinder the ventures growth and success opportunities.
