Some of the most studied internationalization models that explain the rapid internationalization process were reviewed in order to compare the main characteristics of each theory. Methodologically the chapter uses primary data, obtained from an interview, complemented by the analysis of secondary data. A synthesis table seeks to summarize the characteristics of the internationalization process of each of the four theories analyzed.engbook part2026-01-27cv-prod-445881610.4018/978-1-6684-6845-6.ch002
