How it runs

01Discovery sprintOne week with your team: what the app or integration must do, who uses it, what it connects to, and the risks. You leave with an architecture and a fixed quote, and the sprint fee is credited to the build.
02BuildWeekly demos on real devices or a preview URL. Every change passes a build and test gate before you see it.
03LaunchWe handle App Store submissions (and Play on request) or the production deploy, with monitoring in place on day one.
04CareHosting, monitoring, fixes and an SLA, on the tier that fits how critical the system is.
