Born and raised in Madrid, Borja moved to London in 2009 to begin his professional career at Goldman Sachs where he spent three years as an interest rated trader. In 2012, Borja left his conventional life in London for Uganda. There he built Matoko Fund, a social enterprise that was not only entrepreneurially fulfilling, but also the genesis of his passion for mission-driven work. The Matako Fund provided micro-leasing services to women in rural regions of Northern Uganda. The success of the Matako Fund ignited Borja’s passion to create technology that would enrich lives similar to those he was able to help in Uganda. Borja knew he would need additional skills to scale even bigger projects, so he enrolled at MIT as a Legatum Fellow and obtained an MBA focused on Technology and Entrepreneurship.

He then moved to California to become a VC investor and ultimately began working at FJ Labs, first as an investor and later as an Entrepreneur in Residence (EIR). It was during this time that he helped create Merlin, a venture that allows him to satisfy his desire to create tech that serves and emboldens the underserved. He has been leading Merlin as Co-CEO since 2016 and is determined to transform the future of jobs. Borja lives in NYC and loves rock climbing. He was featured in Forbes 30 under 30 Spain in 2017.
