The Indexa Exchange Group is activating the Africa Tech 50 Index (AT50) at the Johannesburg Stock Exchange on July 15. The index, which serves as a benchmark for 50 of the continent’s leading scaled private technology companies, was previously launched at the London Stock Exchange earlier this year. This phase aims to improve visibility and capital markets readiness by connecting private-market growth directly with African institutional investors and exchanges. The AT50 uses a rules-based methodology to track performance and governance, providing a structured way for the market to evaluate Africa’s maturing tech sector.
