Trainstop, Australia’s sports recruitment app, connects clubs with athletes by allowing searches through over 5,000 player profiles. Developed by Codezzi, the app ensures that clubs can contact players directly. As user numbers and data grew, search times slowed, causing potential users to abandon the platform. This performance issue threatened the app’s core function, as a slow search feature undermines the app’s recruiting marketplace value.

The slowdown in search functionality directly impacts user engagement and revenue. In a recruiting app, the ability to quickly discover and connect with potential players is crucial. When search times increase, clubs are less likely to explore and players are less likely to apply. This reduction in user activity weakens the app’s trial motion, where initial user experiences shape long-term engagement. Leaders of such platforms often face delivery anxiety when unable to pinpoint the cause of these performance issues.

To address these challenges, Trainstop treated search as a product surface with a defined budget. They measured the full user journey, from input to the first usable result, and implemented four key decisions. These included defining speed in user terms, reducing work per query, protecting speed under load, and adding a release gate to block performance regressions. By setting a performance budget that matches the business value, Trainstop ensures that performance is a revenue constraint, not just a feature.

The approach taken by Trainstop can be emulated by other apps. By picking one journey to measure consistently and setting a performance metric, teams can ensure that their product surfaces remain fast. Blocking regressions at release, rather than after user feedback, helps maintain performance standards. This strategy offers a roadmap for developers to prioritize performance as a key business driver.
