María Asunción Aramburuzabala
María Asunción Aramburuzabala Larregui (born May 2, 1963), affectionately known as Mariasun, is a Mexican billionaire businesswoman and investor who chairs Tresalia Capital, a family office and venture capital firm. She is the second-richest woman in Latin America and one of the wealthiest individuals in Mexico.
Aramburuzabala is the granddaughter of Félix Aramburuzabala Lazcano-Iturburu, a Spanish Basque immigrant who co-founded Grupo Modelo - the Mexican brewery famous for Corona beer - in 1925. Following her father's unexpected death in 1995, she successfully defended her family's stake against hostile acquisition attempts and transformed the inheritance into a diversified investment empire.
When Grupo Modelo was acquired by Anheuser-Busch InBev in 2013 for $20.1 billion, the Aramburuzabala family pocketed at least $3 billion from the transaction. Maria Asunción used part of the proceeds to acquire AB InBev shares and joined the global brewer's board of directors, where she served for a decade until stepping down in 2023.
As of 2024, Forbes estimates her net worth at approximately US$8.2 billion.
Early life and family background
María Asunción Aramburuzabala Larregui was born on May 2, 1963, in Mexico City, Mexico. She came from a family with deep roots in Mexico's brewing industry and strong ties to Spain's Basque country.
Spanish Basque heritage
Her paternal grandfather, Félix Aramburuzabala Lazcano-Iturburu, was a Spanish Basque immigrant who arrived in Mexico in the early twentieth century. In 1925, Félix and his friend Pablo Díez Fernández co-founded Cervecería Modelo, the brewery that would grow into one of Mexico's most valuable companies and creator of the Corona brand.
The partnership between the Aramburuzabala and Díez families would shape Mexican brewing for nearly a century.
Parents
Her father, Pablo Aramburuzabala Ocaranza, inherited his father's position in the family business and rose to become Executive Vice President of Grupo Modelo. He was a powerful figure in Mexican business circles and groomed to eventually lead the company.
Her mother, Lucrecia Larregui González, was a Mexican painter whose own father, José Larregui Iriarte, was a Navarrese miller who had also immigrated to Mexico from Spain.
Growing up in Mexico's business elite
María Asunción grew up in the privileged world of Mexico City's business aristocracy. Her childhood was shaped by her family's position in one of Mexico's most successful companies and by the cultural heritage of the Basque diaspora in Mexico.
Education
Aramburuzabala attended the Instituto Tecnológico Autónomo de México (ITAM), one of Mexico's most prestigious private universities, particularly known for its programs in economics and business. She majored in accounting, gaining the financial expertise that would prove essential when she later assumed leadership of her family's business interests.
ITAM's rigorous curriculum and its reputation for producing Mexico's financial and political elite provided Aramburuzabala with both technical training and valuable networks in Mexican business circles.
Early career and father's death
For much of her early adult life, María Asunción remained in the background of Grupo Modelo's operations. Her father Pablo was the family's representative in the brewery's leadership, and there was no expectation that she would play a prominent business role.
The death of Pablo Aramburuzabala (1995)
Everything changed in 1995 when Pablo Aramburuzabala died unexpectedly of lung cancer at the age of 63. His death created a leadership vacuum and, crucially, left his family's substantial stake in Grupo Modelo vulnerable.
At 32 years old, María Asunción suddenly faced the challenge of protecting her family's legacy in a male-dominated industry and business culture that traditionally passed leadership through male heirs.
Fighting for control
Following Pablo's death, several groups attempted to gain control of the family's share in Grupo Modelo. The inheritance was valuable enough to attract predatory interest from competitors and opportunists.
María Asunción proved unexpectedly formidable. Together with her mother and sister, she formed an alliance to protect the family's interests - a partnership that would give rise to the name of her future company.
Tresalia Capital
Founding and philosophy
In 1996, María Asunción founded Tresalia Capital, a family office and investment vehicle. The name derives from "tres aliadas" - Spanish for "three allies" - referring to María Asunción, her mother, and her sister who had united to defend the family's Grupo Modelo stake.
Tresalia was created to diversify the family's investments beyond brewing and to professionally manage their growing wealth. The firm would evolve into one of Latin America's most significant family offices.
Investment strategy
Under Aramburuzabala's leadership, Tresalia developed a sophisticated investment approach spanning multiple asset classes:
Private equity: Tresalia invested in and exited businesses including Mexican media company Grupo Televisa.
Consumer goods: The firm allocated capital to consumer-goods giant Kraft Heinz and participated in JAB Holding Co.'s multibillion-dollar coffee investments.
Fashion and retail: Investments included fashion brand Tory Burch.
Technology and infrastructure: Tresalia invested in data center operator Kio Networks.
Real estate: The family office developed significant real estate holdings in Mexico and internationally, including investments in Spain's property market.
Leadership transition
As Aramburuzabala approached the age at which her father died, she became determined to avoid a similar succession crisis. In recent years, she recruited Rodolfo Perez from Goldman Sachs to serve as CEO of Tresalia, while she retained the chairman role.
This deliberate succession planning - rare among first-generation wealth creators - reflects lessons learned from her father's sudden death and the chaos that followed.
Grupo Modelo and AB InBev
Vice Chair of Grupo Modelo
After successfully defending her family's stake in 1995-1996, Aramburuzabala became Vice Chair of Grupo Modelo in 1996. The position gave her formal authority within the brewery and marked her emergence as a business leader in her own right.
She proved an adept negotiator and strategic thinker, earning respect in a male-dominated corporate culture that had not expected leadership from a woman.
The AB InBev acquisition (2013)
On June 4, 2013, Anheuser-Busch InBev completed its acquisition of Grupo Modelo in a transaction valued at $20.1 billion. The deal brought Corona, Modelo Especial, and other iconic Mexican beer brands under the umbrella of the world's largest brewing company.
The three Mexican families who controlled Grupo Modelo - the Aramburuzabalas, Díezes, and Fernándezes - received substantial proceeds. According to Bloomberg's wealth index, the Aramburuzabala family alone received at least $3 billion from the sale.
AB InBev board membership
Rather than simply taking the cash and walking away, Aramburuzabala used part of her proceeds to purchase AB InBev shares and joined the global brewer's board of directors. She served alongside Valentín Díez Morodo, another descendant of a Grupo Modelo co-founder, maintaining the founding families' connection to the business they had built.
Aramburuzabala served on AB InBev's board for a decade, gaining experience in global corporate governance and the international brewing industry. She stepped down from the board in 2023.
She also served on the board of beauty company Coty Inc., though she resigned from this position in 2024, leaving her without board roles at any publicly traded companies.
Personal life
First marriage
In 1982, at age 19, María Asunción married Paulo Patricio Zapata Navarro. The couple had two children: Pablo and Santiago.
The marriage lasted fifteen years before ending in divorce in 1997, during the tumultuous period following her father's death and her emergence as a business leader.
Marriage to Tony Garza
On February 26, 2005, María Asunción married Tony Garza, the United States Ambassador to Mexico, in a small religious ceremony in Mexico City. A civil ceremony followed on April 23 near Valle de Bravo, west of Mexico City.
The wedding was considered the social event of the year in Mexico. More than 800 guests attended, including U.S. First Lady Laura Bush, Texas Governor Rick Perry, and Mexican billionaire Carlos Slim. The marriage represented a remarkable union: one of Mexico's wealthiest women and the American diplomat charged with managing one of the world's most important bilateral relationships.
Garza, a Texas Republican, had been appointed ambassador by President George W. Bush in 2002. His marriage to Aramburuzabala inevitably raised questions about conflicts of interest, though both maintained that personal and professional matters were kept separate.
The couple divorced in May 2010 after five years of marriage.
Current life
Having stepped back from active board roles, Aramburuzabala now spends more time on personal interests including travel and animal photography. She maintains residences in Mexico and has real estate investments in Spain.
Controversies
Pandora Papers
In October 2021, María Asunción Aramburuzabala was named in the Pandora Papers, a massive leak of financial documents that revealed hidden offshore wealth belonging to political leaders, celebrities, and business figures worldwide.
The leaked documents revealed that Aramburuzabala held investments through a New Zealand-based entity called the Sky Chariot Trust. The offshore structure held assets including two private jets.
While the use of offshore trusts is not inherently illegal, the Pandora Papers revelations drew criticism regarding transparency and the use of tax havens by the ultra-wealthy. Aramburuzabala did not publicly comment on the revelations.
Gender and business culture
Throughout her career, Aramburuzabala navigated the challenges of being a woman in Mexico's traditionally male-dominated business elite. Her emergence as a leader following her father's death was itself controversial in a culture that often expected women to cede business leadership to male relatives.
Her success opened doors for other women in Mexican business, though she has not positioned herself publicly as a feminist or advocate for women's advancement.
Philanthropy
Aramburuzabala has engaged in philanthropic activities through various channels, though she maintains a relatively low public profile regarding charitable giving. Her focus areas have included education and arts, consistent with her family's cultural heritage.
Recognition
- Forbes Billionaires List - Consistently ranked among the world's wealthiest individuals and as Mexico's richest woman
- Bloomberg Billionaires Index - Listed as the second-richest woman in Latin America
- Pioneer in Mexican business as one of the first women to lead a major family business empire
Legacy
María Asunción Aramburuzabala's career represents a transformation in Mexican business culture. Thrust into leadership by tragedy at age 32, she not only preserved her family's brewing legacy but expanded it into a diversified investment empire worth more than $8 billion.
Her story illustrates both the opportunities and obstacles facing women in Latin American business. She succeeded in a culture that did not expect female leadership, yet her path was enabled by inherited wealth and family connections that most women do not possess.
The professional succession planning she implemented at Tresalia - hiring outside executives and preparing for generational transition decades in advance - offers a model for other family businesses seeking to avoid the crises that often accompany founder deaths.
Her decade on AB InBev's board connected Mexico's brewing heritage to global corporate governance, while her investment portfolio through Tresalia has supported companies across consumer goods, technology, fashion, and real estate.
