Our Story
In 2021, two St. Stithians students ran a tutoring initiative and saw the exact moment learners gave up. Four years later, they built the platform they wished had existed.
Where It All Began
In 2021, during their matric year at St. Stithians Boys' College, Tyrone Kasi and Zarret Mills co-managed the tutoring initiative for Mountstephens boarding house. Together, they tutored younger students in STEM subjects and organised other matrics to cover subjects they didn't take.
They witnessed firsthand what happens when a teacher has to manage 25 boys in a 45-minute period. They saw the moment students gave up—not because they lacked potential, but because no one could identify why they were struggling before the next concept was introduced.
A test comes back: "Michael got 45%." But which of the hundreds of mathematical concepts is he missing? Which foundational gap from Grade 9 is blocking his Grade 11 calculus? Teachers simply don't have the time to diagnose this for every student. Even at elite schools, parents pay R400+ per hour for private tutors, and the school sees zero data from those sessions.
Years later, they built the platform they wished they had when running that programme. One platform. One profile. Complete visibility. StudiBuddi launched in 2025—teachers finally see not just that students fail, but exactly why—and can act on it.
