Union54
Financial technology company that offers card issuing services without needing a third party processor
About Union54
Based in Lusaka, Zambia, Union54 offers an application programming interface (API) that enables other companies, primarily African fintechs, to issue virtual and physical debit cards without needing to partner with a bank or a third-party processor. The company was founded in 2021 by the husband-and-wife team Perseus Mlambo and Alessandra Martini. Their journey began with a previous venture, Zazu, a neobank launched in 2015. Frustrated by the 18-month wait and complexities of issuing debit cards for Zazu, they decided to build the underlying technology themselves, which evolved into Union54.
Read full description
Union54's core business is to provide the infrastructure for other software companies across Africa to create and manage their own card programs. The platform handles services like BIN sponsorship, transaction processing, and settlement, all accessible through its API. This allows clients to design and issue multi-currency debit cards that can be customized for specific uses, such as corporate expense cards or for customers of digital banks and buy-now-pay-later services. The business model is primarily pay-as-you-go, charging fees for API calls, card issuance, and transactions. The company's name is a nod to the 54 countries in Africa, reflecting its continent-wide ambition.
The company was the first Zambian startup to be accepted into the prestigious Y Combinator accelerator in the summer of 2021. It has attracted significant investor interest, raising a $3 million seed round in October 2021 and a $12 million seed extension in April 2022, with both rounds led by Tiger Global. In mid-2022, Union54 faced a major challenge with a surge in chargeback fraud, which led to a temporary suspension of its services to overhaul its systems. Following this, the company pivoted to develop ChitChat, an integrated messaging and payments platform that combines secure chat with USD virtual Mastercard debit cards and cross-border payment capabilities. This new direction aims to tackle the high cost of remittances in Africa while building a more robust and secure financial ecosystem.
