Aleph did not reveal any financial terms of the investment but said Twitter's stake buy would help the company expand its educational tech platform.
Emerging markets-focused Aleph, which helps large digital platforms connect with advertisers and customers, counts Meta Platforms Inc, Spotify Technology SA and Microsoft Corp-owned, LinkedIn among its customers.
Aleph is Ad Dynamo's parent company and is based in Cape Town. Ad Dynamo has been Twitter’s sales partner in Africa since 2013.
Despite wide-ranging supply chain disruptions that delayed products from reaching shelves and a user privacy clampdown by Apple Inc that many feared would disrupt mobile advertising, brands have continued to advertise online.
