TEWÁ 225


When the Territory joins the forces with the feminine of Ewá, the sun sets on a horizon of socio-environmental harmony. 

Tewá means “technology” in the Yorubá language, social technology that we build in partnership with our customers in all sectors of the economy. 

We weave social transformation through the application of socio-economic knowledge in the areas of sustainability and public policy, in all sectors of the economy. 

But for us to do this in a way that generates shared value, we need to know that the path matters as much as the destination. Therefore, article 225 (Brazilian Constitution of 1988) guides our practice, making it democratic, participative, involving, so that society can co-create its future.

We are a company led by women guardians of important knowledge in the socio-environmental area. Get to know our work and weave this story with us.

No que Acreditamos


Know to Transform

The generation of content, data and social indicators is just the starting point for a sustainable and restorative practice. It is necessary that the reading of these contents become narratives and be appropriated by the actors who participate in the change process.

Leadership with Participation

All truly transformative processes engage their participants in the joint construction of the result. This is not to say that there is no leadership. On the contrary, when the process is open to dialogue, natural leaders appear and are strengthened by the collective.


We believe that it is necessary to ask permission when we enter someone else's house (LSO), however we can be visitors with empty hands or take something to share together. Generating shared value is the starting point for social licensing.

State, cradle of conciliation

The State in its essence has several theoretical meanings. We believe that it is a web of relations between groups, mediated by laws and bureaucracies that allow for the conciliation of interests. In this sense, the involvement of public authorities and the opportunity to create transformative policies serve different interests, generating benefits for communities and monitoring relationships.




Companies, social organizations and governments. These are the agents of the transformation we believe in. Our company has experience in working with all of them and believes that it is in building governance and partnerships that we can achieve our purpose.

Nowadays it is possible to obtain services in the area of socio-economic research with different organizations. However, research, when carried out by specialist researchers, is a great tool for inclusion and awareness. Our team is made up of social scientists with extensive experience in theoretical and empirical research, whose aim is not to gather information, but to generate value for the client and the community.



In the market of competition and individuality, values such as listening, welcoming, raising awareness and acting together are differentials. Our company is led by women engaged in social transformation, for whom the “how” we do matters as much as the result achieved.

It is possible to carry out great transformations from a distance and in the digital age we can see many opportunities. However, our team is made up of consultants with solid field experience, dialogue tools and community empowerment, as well as an immense pleasure in getting to know the different realities with their own eyes.



The work is planned to generate shared value and with a focus on knowledge management. We ensure reports and presentation of results with quality standards and support the client from the stage of defining the scope of work because we are loyal to what we are committed to.
