Our Team

A5X is driven by people who know the market inside out—and who have decided to transform it.

Our team brings together professionals who have operated, regulated, innovated, and built at the heart of the financial system. People who combine strategic vision, precise execution, and a genuine commitment to investors.

More than solid track records, what unites us is a clear purpose: to transform the stock exchange sector into a more efficient, robust, innovative, and transparent environment.

Every decision is guided by our pillars, and each delivery carries the responsibility of those who understand the systemic relevance of a stock exchange to the entire ecosystem.

Diversity is part of who we are

At A5X, we believe that true innovation is born from the encounter between different perspectives

We are building a new exchange, and we know that this journey is only possible with an inclusive, safe environment, open to all voices. The diversity of backgrounds, trajectories, cultures, and identities strengthens us and makes us more creative, fair, and human.

This plurality also translates into deep knowledge and solid experience in different sectors, which complement each other and provide the necessary foundation to build a robust, innovative, and efficient business.

We want a team where each person shines as who they are — and, by combining talents and stories, build the future of the market with us.

The strength behind A5X: experience, vision and execution.
