How We Built a Complete AI SaaS Product — Accounts, Metered Billing, Calendar Sync, and a Mobile App — as Our Own Build

We proved out a usage-based AI product end to end on its own dime: real accounts, real payment, real third-party integration, and a native mobile wrapper.

How we did it

Step 1
Full Product Architecture
Real user accounts on a modern web stack, built end to end.
Step 2
Metered Billing
Pay-as-you-go credits billed through Stripe from day one.
Step 3
Calendar Integration
Syncs directly with Google Calendar.
Step 4
Native Mobile Wrapper
Packaged as a native iOS/Android app around the same web product.
