THATO SEBASTIAN-CHARLES MMEREKI was born in Kuruman, in South Africa's Northern Cape, into the particular silence that follows a country's unacknowledged catastrophes. He came of age in the years when South Africa was relearning what it meant to be seen — and what it cost.

He served as spokesman and personal aide to Winnie Madikizela-Mandela in the years before her death in 2018: years in which he sat with her at kitchen tables and in the margins of official history, and was entrusted with the private record of what the public account had agreed to leave out. Before that, he worked as a technical producer and journalist at the SABC, and later as a senior adviser in the Office of the Premier. He has spent his career at the place where power and narrative meet — learning, at considerable personal cost, that the two are never the same thing.

Thato is a strategic executive and sovereign venture capitalist operating across Africa and global markets. He leads high-impact initiatives in geopolitics, infrastructure, and governance, building resilient institutions and transformative cross-border partnerships that drive inclusive growth and long-term continental prosperity.

He serves as President of SBM-DevCO, Chairman of South Africa's National Gambling & Wagering Policy Council, and Chief Financial Officer of the China–South Africa Forum. As Architect of the China–Africa Luban Workshops, he provides strategic advisory on Belt and Road Initiative projects across Africa, with additional advisory roles at the Public Relations and Communications Association of Africa, The Nikela Trust, Queens Commonwealth Trust, and One Young World.

What Light Cannot Touch is his first book.

He lives in Johannesburg.
