A few weeks ago I rediscovered a project, ayudame3D, and an exceptional social entrepreneur, Guillermo Martínez Gauna-Vivas. I say ‘rediscovered’ because, after a bit of ‘research’, I realised that he ‘sounded familiar’, as he was one of the winners of the Princess of Girona Foundation‘s 2020 Princess of Girona Social Award. Today I would like to introduce him to you, because what he does contributes to improving the world and, above all, to changing the lives of vulnerable people.
