Based in Coral Gables, Florida, Mas Alpha Securities was founded in 2023 following a three-year acquisition expansion at MasTec, Inc. During that period, Jose Mas, Jr. was directly involved in over $3 billion of M&A transactions, gaining meaningful exposure to large-scale infrastructure assets and developing a clear conviction for long-term ownership in the sector. Inspired to extend his family’s legacy from infrastructure construction into infrastructure ownership, Mas Alpha Securities was established.

Today, Mas Alpha Securities invests across both public and private markets. Our investment philosophy centers on owning irreplaceable assets with substantial barriers to entry. We seek opportunities in deeply misunderstood or overlooked businesses where intrinsic value is materially disconnected from market perception, allowing us to compound capital over extended periods of time.

We take a generational approach to investing and therefore do not operate within predefined holding periods. Our objective is to own businesses and assets that can withstand the test of time across economic cycles while benefiting from long-duration structural demand.

Since inception, the firm has grown steadily, assembling a focused team of young yet experienced finance and operations professionals who pair disciplined execution with ambitious vision.

The firm operates with a highly collaborative structure, with senior leadership engaged across all investments and initiatives. CEO and CIO Jose Mas is joined by Moises Jattin, who leads special projects and partner relations, and Gaby Freire, Chief Financial Officer, who oversees financial reporting across the firm’s privately held portfolio. With an average front-office age under 28 and a demonstrated record of execution, the team’s energy, alignment, and long-term time horizon represent a distinct competitive advantage.
