The challenge

Astro Africa lets people in Nigeria and Ghana sell, buy, hold and swap crypto and sell gift cards, then get paid to a bank or mobile money. The product was live, the codebase had grown hard to change, and the brand no longer matched the ambition. Everything had to be rebuilt without stopping a business that moves customers’ money every day.

Our role
  • Brand refresh and design system
  • iOS and Android app (one Flutter codebase)
  • Customer web app
  • New admin dashboard for operations
  • Marketing website with SEO rate pages
  • Partner API, push engine and AI support assistant
  • Security review and hardening
Built with

How we approached it
  1. 01

    Audit first

    We started with a security and code audit of the existing system, fixed the riskiest issues, and only then began the rebuild.

  2. 02

    Design the whole journey

    Every flow — swap, sell gift card, withdraw, send by AstroTag, automated payouts — was designed light and dark before code.

  3. 03

    Ship in slices

    New screens, the web app and the admin went live one at a time, each with separate staging and live environments and a rollback plan.

  4. 04

    Keep it fast to find

    A new static website on Cloudflare with live rate pages, structured data and a clean sitemap.
