Sam Zell and Maria Asuncion Aramburuzabala are two names that often appear together in discussions about global business, investment, and wealth. However, their stories are very different. Zell built his fortune through real estate deals and corporate investments in the United States. Aramburuzabala came from the family behind Grupo Modelo, a major Mexican brewing company, and later turned that inheritance into a broad investment portfolio. This article looks at who they are, how they built their wealth, and what actually connects them.
What Connects Sam Zell and Maria Asuncion Aramburuzabala?
There is no evidence that Sam Zell and Maria Asuncion Aramburuzabala were married, related, or long-term business partners. Their careers grew separately.
The connection between them comes from shared investment circles in Mexico. A 2007 business report said that Javier Barrios, who had worked with a real estate company owned by Aramburuzabala, was hired by Zell to help start a new Mexican real estate fund. Another report from El Economista listed both Zell and Aramburuzabala as investors linked to a Mexican private equity firm called Nexxus Capital.
These connections explain why their names appear together. They were not direct partners, but their investment networks overlapped in Mexico.
Who Was Sam Zell? His Early Life and Career
Sam Zell was born on September 28, 1941, in Chicago, Illinois. His parents were Polish immigrants who had survived the Holocaust. He studied at the University of Michigan, where he earned a law degree in 1966.
Zell started investing in real estate while he was still a student. In 1965, he bought a small apartment building. In 1968, he founded Equity Group Investments, the private investment company that became the base for his later business activities. Over the years, he expanded into many industries, including manufacturing, energy, healthcare, and logistics.
Zell became known for buying distressed or undervalued assets that other investors avoided. This approach earned him the nickname “Grave Dancer.” He believed that some assets were worth more than the market thought. His focus was always on the risk, not just the potential reward. He once said, “The key to my success is that my focus is never on how good it’s going to get. My focus is on the percentage that it doesn’t work.”

When her father died of cancer in 1995, Aramburuzabala inherited his stake in the family business. She was only 32 years old and had no plan to succeed him. She worked with her mother and sister to protect and manage the family’s interests.

One of the most important parts of Aramburuzabala’s career is Tresalia Capital. She founded the company in 1996 with her mother and sister. The name “Tresalia” refers to the idea of three allied women.
Tresalia is a family office and investment platform. It invests across many areas, including private equity, venture capital, financial services, technology, and real estate. The firm has investments in companies like Banco Santander, BBVA, América Móvil, and Televisa. In venture capital, Tresalia has invested in startups like Kavak and Luuna.
Its real estate division is called Abilia. Abilia has developed more than 3 million square meters of residential, corporate, and commercial projects across Mexico. It also owns 1,000 multifamily rental units in the United States.

The Grupo Modelo Deal and Her Business Success
The sale of the family’s Grupo Modelo stake was a major turning point in Aramburuzabala’s business story.
The Sale of Grupo Modelo
Anheuser-Busch InBev completed its acquisition of Grupo Modelo in June 2013. The transaction was valued at $20.1 billion. The deal made Corona and other Modelo brands part of the world’s largest beer company. As part of the deal, Aramburuzabala and Valentín Díez Morodo were invited to join AB InBev’s Board of Directors.
How the Deal Shaped Her Wealth
The sale gave the family a huge amount of cash. Instead of keeping the money in one place, the family used it to invest across different sectors and regions. This diversification is a key part of Aramburuzabala’s success. Her wealth is no longer tied only to beer. It now comes from investments in finance, technology, real estate, and more.
In 2026, Forbes Mexico estimated her family fortune at $9.3 billion. She is considered the richest woman in Mexico.
