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, targeting differentiated real-world opportunities defined by durable competitive advantages, deep unrealized value, and the capacity for long-term operational excellence. Our hybrid investment strategy enables us to capitalize on exceptional opportunities across both public and private markets. This flexibility allows us to prioritize mispriced or underappreciated opportunities in any market.

Unlike conventional private equity, we are not constrained by predefined exit timelines. We invest with a long-term orientation, emphasizing durable competitive advantages, consistent cash flow generation, operational excellence, and sustained capital appreciation.

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.
