History
The party was launched on 24 September 2022 in Naledi, Soweto.[4] The deputy leader is Nobuntu Hlazo-Webster, founder and convener of the South African Women’s Commission. The chairperson of the party is the current Nelson Mandela Bay deputy mayor Mkhuseli Jack.
The party contested its first by-election in October 2023, winning 1% of the vote in the ward one election in Sol Plaatje Local Municipality.[5]
The party contested the 2024 general election as an "umbrella organisation" for independent candidates.[6] Maimane stood as the party's presidential candidate in the elections.[7] The party received around 0.4% of the national vote in the election.[8]
Merger
On 5 October 2025, the party announced its merger with Good and Rise Mzansi to form Unite for Change, a new party that was intendeded to be registered to contest the 2026 municipal elections. Build One South Africa will continue to exist independently until the 2029 national elections, after which it will fully merge into the new party.[9]
The merger was put on hold in April 2026, with the three parties stating that "it cannot be implemented effectively under the pressure of an election campaign. As a result, the parties have determined that the best option is to contest the 2026 local government elections individually and pursue consolidation afterward".
In the meantime, BOSA merged with the People's Prosperity Movement, a small party based in the Western-Cape .[10]
