We invest with a long-term horizon and no fixed end date, allowing us to back exceptional opportunities and let them compound over time. We pair ambition with patience—pursuing outsized outcomes while staying grounded in people, integrity, and the relationships that endure. We embrace technological change as a driver of progress and partner with those building what comes next, guided throughout by a deep respect for the human values at the heart of every great enterprise.
Our leadership is guided by the example of Irene Vázquez Mier—grandmother of our founder and a pioneer who helped build one of Spain's first business schools, devoting her life to independent thinking, the advancement of women in professional life, and the enduring value of knowledge. Her ambition, integrity, and humanism remain the standard we hold ourselves to.
