From the review of national and international literature on inclusive business, two theoretical definitions were identified: pyramid base (BPO), in which the low-income person is not seen only as a less fortunate being in society, but as a consumer (PRAHALAD; HART, 2008; SHYAM, 2017; BECKWITH, 2016) and value chain, which includes people or groups excluded from its chain, such as suppliers, resellers and other publics (TEODÓSIO; COMINI, 2012; PETRINI; SCHERER; BACK, 2016; GOLJA; POZEGA, 2012). Another observation is that the academic literature on Administration is rarely concerned with understanding poverty, social exclusion/inclusion, on the contrary, it occurs in social sciences (LARSEN; ANDERSEN; BAK, 2012; SAWAIA, 1999; ROOM, 2002; SAUNDERS; NAIDOO; GRIFFITHS, 2008; BAK, 2018; SPOSATI, 1998). Therefore, opportunities for critical analysis of current definitions and the proposal of an unprecedented definition are perceived. For this, we sought to answer: a) What are the theoretical definitions about inclusive business? b) What are the perspectives and approaches not yet debated in the scientific literature? c) How can the theoretical understanding of social exclusion/inclusion from the social sciences contribute to the understanding of what gender inclusive business is? d) How do companies that call themselves or are considered gender inclusive businesses deal with poverty, exclusion, and social inclusion? The methodology included exploratory research and gender case studies. As an answer to the first question, two theoretical definitions were identified: on the base of the pyramid and value chain and others partially debated: On Rights (Advocacy) and Self-inclusion (COSTA, 2019); Recognition, Self-Respect, and Inclusion (HAHN, 2012) and Extended Resources ("wasted") employ more excluded people (RANJATOELINA, 2018). As for the second question, in gender case studies, it was identified value chain, base of the pyramid and two partially debated definitions were found: indications of voice and language inclusion. In the third, it is necessary to recognize the inclusion of low-income people in business but understand of poverty and social exclusion. In the fourth, inclusive business is defined as a type of for-profit company that is characterized by making visible individuals or groups that, in general, differ from the standards established by society, almost always in a context of poverty and, mainly, social exclusion, that is, exposed to situations of social vulnerability, prejudice and social stigma, acting to promote activities that seek to benefit people who are in one or more situations, such as: base of the pyramid, acting in certain value chains, seeking for rights (advocacy), self-inclusion, recognition and self-respect.
