Tandem Social

More than 15 years of transforming vision into impact

More than 15 years ago, we decided to create Tandem, putting our energy, talent, and conviction at the service of building a fairer world for everyone. What began as the vision of a small committed group is today a solid organization with its own distinct character and a working model designed by, for and with people.

We are a team of 50+ experts working across diverse projects and sectors, learning every day to identify emerging needs and respond to them with a combination of strategy and our own methodology. We have already supported more than 400 organizations, consolidating our position as a benchmark in driving projects with real and lasting impact. Our horizon is still, and always will be, for every project to become a tool for social transformation.

our reason for being

Our purpose is driven by the commitment and passion to contribute to a fair and inclusive society and economy in the social and environmental spheres through a strategic and collective vision.

We are a team that believes in what we do

We are guided by firm values:


  • Vocation for service, quality, and knowledge
  • Involvement, proximity, and teamwork
  • People at the center and intercooperation as a driving force
  • Commitment to social transformation

We operate in an ecosystem of intercooperation

We understand that transformation is not generated in isolation, but rather through an ecosystem of intercooperation where we promote initiatives, forge alliances and actively participate in organizations that shape transformative responses to today’s major challenges.
