Mongolia has a unique civilization that merges nomadic and settled traditions. Its economy is dominated by mining, animal husbandry, and agriculture, with mining minerals constituting the majority of its exports. The development of production began in 1924, and most factories were privatized during the 1990 Democratic Revolution. This study aims to highlight hidden champions operating in Mongolia. Enterprises were selected based on three main criteria defined by research scientist Simon, and individual interviews were conducted. In recent years, Mongolian brands have made significant strides in the global market, marking a major advancement for a developing country. The number of companies aiming to compete internationally has risen, with many showing rapid development—a positive indicator for the economy. Lately, small and medium-sized enterprises in Mongolia have increasingly turned to foreign markets to sell their products and services, driven by the shrinking domestic market and the impact of the pandemic. For Mongolia’s hidden champions, the intensified focus on e-commerce and services during the pandemic has proven successful. Looking ahead, the expansion into foreign markets is set to further encourage the growth of e-commerce and broaden their activities across more countries. Following the COVID-19 pandemic, many small and medium-sized enterprises are focusing on recovering their losses and paying off debts. Simultaneously, the pandemic has spurred an increase in e-commerce abroad, presenting new opportunities for Mongolian businesses.
