The Stakeholders Sustainable Index (SSIndex) captures the behavioral aspects of environmental, social and corporate governance variables (ESG), cross-analyzing information from stakeholders, including employees, clients, suppliers, communities, investors, and others.\\The SSIndex helps investors and lenders to identify which are the companies that are tracking the behavioral risks on ESG, to anticipate: frauds, strategy miss-alignments, and operational inefficiency. The SSIndex also provides a software tool for companies to help them take immediate action on such behavioral risks with a level of granularity of groups up to 4 people. \\Developed under the supervision of Yale University professors', the SSIndex complements current sustainability indexes, with information over stakeholders' behavior to identify impact. On that regard, stakeholders might have a positive, negative or neutral definition to the practices and procedures reported, as a line of relevant information to lead market value.
