The story

Tumisang Ikefuna-Ramarea was born in 1994 in Kanye, Botswana. Nicknamed "Radio Botswana" as a child for his constant chatter and inquisitive nature, he entered primary school in 2001 already ahead of his peers, having been taught to read and count by an older brother. He topped every class he attended and served as student council president at Seepapitso Senior Secondary School, where he competed principally against his own previous scores.

In 2013 he won a United World College scholarship and relocated to UWC Costa Rica — his first time far from home, and the experience that permanently challenged everything he thought he knew about himself and the world. He went on to Stanford University, where he earned his Bachelor's and Master's degrees, studying Decision and Risk Engineering, among other disciplines, under world-class faculty.

Professionally he works in product management, driving innovation from the intersection of technology and human needs. Outside work he is a writer — more than 70 blog posts published since 2018, poetry in English and Setswana, and short fiction. He also built the Edge Model, a Bayesian football prediction system that achieved 81% accuracy across the FIFA World Cup 2026 and is now monitoring the 2026–27 club season.

Five values organise his life: Growth, Ubuntu, Creativity, Curiosity, and Excellence. RAMAREA is his attempt to live all five in public. For a longer, richer account — written in the third person to underscore the pseudo-celebrity status he holds in his home village — read The Man & The Myth.
