Challenge
- PCI DSS certification and FCA approval, ensuring full regulatory compliance
- Ultra-low latency transactions under 250 milliseconds, delivering a seamless user experience.
- Successful integration of multiple third-party APIs, including GPS, Xero, and CashFlows
Sidedoor needed to launch a differentiated two-sided property marketplace while addressing scale, usability and demand on both sides.
It had to turn an offline property survey model into a scalable digital platform connecting property buyers and surveyors. The core challenges included:
- Creating a seamless UX for two distinct user groups
- Building a marketplace that balances demand and supply
- Standing out in a crowded property portal landscape
- Allowing for future service expansion
- Delivering quickly on a robust, modular foundation
Sidedoor needed an experienced product and engineering team to design the marketplace experience, build the platform end to end, and create a clear value proposition for both sides of the ecosystem.
