Could you build this?
Partial The developer API and dashboard are straightforward, but the product relies on a proprietary cross-platform mobile client app ecosystem to bypass SMS entirely.
What it would actually take: The architecture comprises a backend API (Node.js/Go) connected to Apple Push Notification service (APNs) and Firebase Cloud Messaging (FCM), paired with native iOS and Android companion apps. The challenge is building and maintaining the multi-tenant mobile client application, managing reliable background push notification delivery, and bootstrapping a two-sided network where end users actually install the app.
