Joylo Ltd is an AI app builder with in-house engineers, based in Dublin, Ireland. The AI builds the app fast. Joylo's engineers make sure it survives real customers. Every build is scored on scalability, security and reliability before it ships.
Joylo exists because of the gap everyone building with AI hits: the demo works, then real users arrive. AI writes code fast. It does not own the result at 3am when the database is down.
So Joylo pairs the two. The AI builds the app. In-house engineers stand behind what ships, backed by a written production guarantee. Every build is audited across five domains: scalability, security, reliability, integrations and code quality. When something breaks, Expert Assist puts a named engineer in the codebase for a fixed price.
