This research analised the characteristics of four brazilian companies, that belongs to Communion Economy Project - EdC, trying to compare their behaviour as a whole with the guidances of Stakeholder Theory. Besides, another comparison has been made among the social scorecards of these companies, using the framework of Instituto Brasileiro de Análises Sociais e Econômicas -IBASE, and the companies that belong to the data base of this organization. By doing that, this paper tried to find out how stands the performance of these four companies, in terms of the corporation social responsability. The main goal of this investigation is to estimate whether or not the four companies, that build up the core or the research, have improved their competitiveness due to EdC distinctive characteristics. The research concluded by creating a concept of Economy of Communion enterprise, giving the companies a road map that allows them to keep closer to the Stakeholders Theory guidelines. To reach such goals, was necessary to take part in two annual National EdC Meeting, that took place at Mariápolis Ginetta, in Cotia, São Paulo, the same place in which the EdC`s project has been released to the world. After that, the four companies has been visited, so that it could be possible to make interviews with some internal and external stakeholders. Besides, several contacts has been made by phone and by eletronic mail with unions and other representatives, and a exploratory survey has been launched in order to reach all ninety EdC companies in Brazil. The research concludes that there is a great similarity between the characteristics of the four visited companies and the Theory of Stakeholdes proposals, although they do not fit perfectly. Mentioning the competitive advantage, it has been recognized that there is, indeed, a great source of it by following the EdC framework, although it is pretty hard to reproduce the same behaviour outside it. In relation with the social performance, the research has noticed that some of them are much better than the IBASE average, even in comparison with big companies.
