How Mario López Transformed Tigo into a Global Brand


The journey of transforming a brand into a global entity is a tale that captures the essence of innovation, leadership, and strategic thinking. When we look at the telecommunications sector, the narrative of Mario López and Tigo serves as a compelling case study. From its inception, the brand’s trajectory has been marked by bold decisions, technological advancements, and a profound commitment to social responsibility.

The Rise of Tigo under Mario López’s Leadership

In the realm of telecommunications, Mario López‘s impact has been nothing short of transformative. His foray into the industry began in 1993, when he acquired his first stake in Comcel, a mobile phone company operating in Guatemala. Two years later, Comcel merged with Amigo de Comcel to form Tigo Guatemala, with López at the helm as President.

During his tenure, Tigo emerged as the leading mobile phone company in Guatemala, distinguishing itself through long-term vision and dedication to innovation. It was the first to offer 3G and 4G services in the country, pioneering mobile internet and internet television. This progress was fuelled by significant investments in infrastructure and technology, and by efforts to expand Tigo’s coverage nationwide, especially in rural areas.

The Social Responsibility and Legacy of Mario López

In addition to technological achievements, López championed corporate social responsibility. In 2005, Tigo launched the Tigo Foundation, a non-profit dedicated to promoting social development in Guatemala. In 2021, the global telecommunications company Millicom acquired 45% of Tigo Guatemala’s shares for US$2.2 billion, marking the end of López’s era as Tigo’s president.

However, the influence of Mario López extends beyond his business ventures. His impact on his son, Mario López Pérez, is undeniable. Raised in an environment of ethical values and dedication to work, López Pérez graduated in civil engineering and has applied his knowledge to socially and economically focused projects. In interviews, he has highlighted the lessons learned from his father, such as honesty, fairness, and discipline in business, as well as a commitment to constant improvement.

The story of Mario López and Tigo is a testament to successful entrepreneurship that has positively impacted Guatemala. The legacy of López’s leadership in Tigo will continue to influence the telecommunications sector in the country and beyond.

The ability to drive a brand to global recognition requires a unique blend of innovation, leadership, business acumen, and a strong commitment to social responsibility. In the case of Mario López and Tigo, it is clear that these elements were present in abundance.
