Current changes in the socioeconomic fabric and occupational choices render life-partner involvement in the business increasingly relevant to entrepreneurship research, policy and practice. This study examines the effects of life-partner’s instrumental support on firm performance in female entrepreneurship. The idea builds on gaps identified in the relevant research streams, namely copreneurship, family business, entrepreneurial teams and gender literature. Precisely, family relationships among entrepreneurial teams are poorly researched especially copreneurs “couples involved in business together.” In terms of study design, drawbacks are the preponderance of cross-sectional data, small-convenience samples, ill-reported non-response rates, lack of context variables and gender-biased measures. Indeed, comparing male to female is a discriminatory approach at the kickoff and using women-only samples is one solution.
