TPaga is a Colombia-based mobile payment platform for the unbanked. In 2017, Silicon Valley fund Green Visor Capital led a US$2.5m investment in Tpaga, and Y Combinator invested US$120k. Co-founder Andrés Gutiérrez talks with LAVCA about how TPaga emerged from running Tappsi, a Colombian taxi app that merged with Easy in 2015, the opportunity to bring mobile payments to the unbanked, and the importance of competition.
