"Just like Alibaba, we're very involved in payments and financing business. Amazon tried to get into payments, but there are other players in that field in the US," he told Argentine paper El Cronista.
Alibaba founder Jack Ma visited the region last year, traveling to Argentina and Mexico, and fueling speculation about a potential bid for MercadoLibre.
MercadoLibre is increasingly betting on financial services, particularly through different forms of investment fund vehicles, and eventually getting to to the credit segment, Galperín said.
MercadoPago, the company's payment processing platform, launched this year, is generating more revenues than the company's marketplace. Recently, MercadoLibre and IDB Invest struck an SME financing deal in Brazil.
Likewise, in July, Banco Patagonia placed a financial trust valued at 271mn pesos (US$7.1mn) in loans issued by MercadoLibre to its member merchants. The trust, the first backed by MercadoLibre merchant loans, is called Mercado Crédito 1.
MercadoLibre also partnered with Argentine lender Banco Industrial (BIND) for an investment fund dubbed MercadoFondo that allows clients to invest in high-yield, short-term securities.
"In less than two months we already have almost 100,000 people investing. What seems fantastic to us is that the average investment is US$150 from people who would never have thought that they would be able to invest," Galperín said about the BIND fund.
"The opportunity is huge because half the population of Latin America is outside the financial system. We're reaching a critical mass that were excluded from this type of savings, from income generation. They can be part of financial inclusion, because paying digitally generates a story that is visible and traceable," said the chief executive.
As for improvements in logistics and shipping, Galperín said MercadoLibre is starting to see results with scale-operating distribution and storage centers opened in Mexico and Brazil, with another one planned for Argentina in March.
Among the planned regulatory changes in Argentina, he praised bills tackling the business landscape for entrepreneurs and SMEs, while criticizing taxes on software exports the government plans to introduce in 2019. "If this is maintained over time, the software industry is going to leave."
In the interview, Galperin also said that Argentina's labor regulations "belong to the past century".
Galperin added that he expects a new unicorn in the likes of MercadoLibre to pop up in Latin America soon, most likely in Brazil.
