The challenge
The client came to us with a clear goal — corporate cards with receipts, limits and instant approvals. The hard part was correctness under concurrency and partial failures.
Our approach
We started with a short discovery sprint to map the users, the data and the constraints, then moved into weekly cycles with working software in a shared workspace. Consulting, Development and Product Research ran as one team, so research fed design and design fed engineering without handoffs.
The platform was built on Payments, Mobile and Ledgers, with automated tests and monitoring from the first release.
The result
10k cards issued. The product launched in 20 weeks and we stayed on for the releases that followed — fixing what users tripped over and doubling down on what they loved.
