Black female executives possess unique leadership capabilities required for Science, Technology, Engineering, and Mathematics (STEM) corporate and societal future development, yet they remain hidden and disproportionate compared to the number of other executive groups. This qualitative study utilized the Bronfenbrenner framework to explore the multidimensional factors affecting Black females in STEM corporations and the cultural historical activity theory (CHAT) framework to examine their attributes and cultural wealth creation. The semi-structured interviews of 15 Black female executives in STEM corporations provided insights into the factors impacting their corporate ascension and cultural wealth creation activities. The research findings highlighted and reinforced the need to maximize the additive element of cultural wealth Black female executives possess in execution, a move toward increasing promotions and output in STEM corporations. Additionally, the research findings illustrated aspects of Black female execution, such as cultural humility, not previously discovered in the literature. Finally, three recommendations are presented for implementation activities to promote Black females in STEM corporations and bridge the gap. Accordingly, corporations should implement programs for early career rotational development for Black females, create branding opportunities, and educate all executives on cultural humility, highlighting Black female executives' strength in execution and providing pathways to ascension.
