The challenge
A Top-10 US processor saw a big invoicing opportunity but had limited engineering resources and no scalable product to sell.
Our approach
OutsideHire delivered an MVP in 9 months at 60-70% less than in-house, then iterated it into a full platform.
The outcome
It became the fastest-growing product in the processor's online payments portfolio and its top-selling software product in 2024 and 2025.
