MEET OUR FOUNDERS

IB45s was founded by Sabrina Ciauri, Tiago Costa, and Alexia Ferreira Correia —three IB graduates from international school backgrounds who combined their academic strengths, global experience, and shared passion for education to create a service that raises the standard of IB support worldwide.

What began with subject-specific tutoring in London international schools has grown into a global network of students, families, tutors, and coaches who trust IB45s for its clarity, consistency, and results.

Together, the founders bring academic rigour, international perspective, and a shared belief in structured, personalised education.
