Arancha Martínez Fernández (1984) graduated in business science and international relations from ICADE. She has also studied history at UNED and has a Master’s in NGO management. At the age of 24 she was already convinced that it was possible to change the world. So, in 2008 she travelled to India as a voluntary worker with one objective: to play an active part in change. While in India she discovered her vocation: applying her knowledge and professional experience in strategic marketing and finance to the social sector in order to maximise the social impact of cooperation and humanitarian projects. In 2009 she set up It Will Be, an organisation that seeks to bring efficiency and professionalism to the humanitarian sector to maximise aid and funds and ensure that they reach many more people. Her greatest achievement to date has been the creation of a system for identifying and tracking undocumented vulnerable groups of people to improve the interventions carried out by NGOs and humanitarian organisations. This novel system will be used shortly in India, Senegal, Tunisia, and the Western Sahara, among other places.
