Building on social-psychological theories of descriptive and prescriptive gender stereotypes and extant entrepreneurship literature, the authors establish that gender biases are likely to occur because of resource providers' perceptions of women entrepreneurs at the helm of male-typed start-up ventures to be less competent and agentic, as well as less warm and other-oriented than equivalent male entrepreneurs leading male-typed start-up ventures. The authors discuss the implications of such gender-biased evaluations for the application of stricter performance standards to female-led-male-typed start-up ventures and the likelihood and conditions of resource provision to their companies. The authors further discuss why and when female founder-CEOs of a female-typed (gender-neutral) start-up venture are likely to be overvalued (equivalued) compared to equivalent male founder-CEOs. The authors also develop propositions on additional contingency factors and mediators of the gendered evaluations of founder-CEOs and their start-up ventures, including resource providers' “second-order” gender beliefs, the high-cost versus low-cost resource commitment, individual differences in gender stereotyping and the perceived entrepreneurial commitment of the founder-CEO. The authors conclude by suggesting some practical implications for how to mitigate gender biases and discrimination by prospective resource providers.
