01 · Problem
What was stuck
50M+ African businesses lack clean employee spend tooling. Any card product that ignores mobile money rails feels imported and gets ignored by finance managers.

02 · What we did
How we shipped
Led with industry scenarios (pharma sales reps, logistics crews). Emphasized instant Visa issuance plus mobile-money workflows, policy limits, and reporting that finance can reconcile without chasing WhatsApp receipts.
03 · Takeaway
Why it mattered
If your sales team lives on the road, the card has to work where the bank branch doesn’t.
Boya targets the gap between plastic corporate cards designed for London and field teams who live on M-Pesa. Instant issuance, limits, and real-time visibility are the product — not another expense spreadsheet.
