Our Founder
Guillermo de Yzaguirre Martínez
Founder & CEO, PBC Languages
I believe language is the ability to connect with someone beyond your own culture.
At 15, I moved to the United States, an experience that changed how I understood language completely. By 16, I was already teaching English to children younger than me. That's when I realised language was not something to study, but something to live and share with others.
Later, I worked within structured online language models and saw both their value and their limits. Learning often felt too standardised and disconnected from real conversation, leaving little space for adaptability and human context.
I founded PBC Languages to build something more alive: a language ecosystem where teachers and students stay connected, and where learning extends naturally beyond the classroom.
