Paystack: Engineering Reliable Payments Infrastructure for Africa

Company Overview: Paystack’s Location, Country, and Offices

Paystack is headquartered in Lagos, Nigeria, with additional offices and teams operating across Accra (Ghana), Cape Town (South Africa), Nairobi (Kenya), and Dubai. The company was founded to solve a critical challenge for African businesses: the lack of reliable, developer‑friendly infrastructure for accepting digital payments at scale.

Paystack operates as a regulated payment service provider across its markets, working under local payment institution frameworks and in close coordination with central banks and financial regulators. Since becoming part of Stripe in 2020, Paystack has retained its operational independence while benefiting from global expertise in payments security, compliance, and scalability.

Products and Technology Strategy

Under Ezra Olubi’s technical leadership, Paystack has built a comprehensive payments platform tailored to African commerce. Core products include online and in‑app card payments, bank transfers, USSD, mobile money, QR payments, subscriptions, invoicing, and merchant payouts.

The platform supports Visa and Mastercard, local bank rails, and real‑time transfer schemes where available.

Strong KYB/KYC flows, fraud detection, AML monitoring, and automated settlement logic are embedded directly into the platform.
