YC-backed Moni Rebrands As Rank, Acquires AjoMoney & Zazzau MFB In Nigeria

YC-backed fintech Moni has rebranded as Rank, unveiling a broader vision to digitise Africa’s centuries-old community finance systems.

As part of the shift, Rank has acquired AjoMoney, the digital group-savings platform, and Zazzau Microfinance Bank, now renamed Rank Microfinance Bank, giving it both product depth and a regulated foundation for deposits, credit and treasury-backed savings.

Rank’s first product is a high-yield group savings solution, built around trusted networks such as traders’ associations and cooperatives. A recent pilot with 10,000 users delivered NGN 16 B (USD 11.25 M) in payouts, backed by treasury bills and money markets with returns reaching 23%.

By blending digitised trust networks with licensed banking infrastructure, the Lagos-based fintech aims to turn traditional Ajo, ROSCAs and community savings circles into scalable, wealth-building vehicles. The company is also rolling out a team of wealth advisors, pairing human guidance with digital tools to support users across their financial journey.
