Readdle Tech Stack

iOS productivity apps with web expansion and revenue scaling focus

IT Services and IT Consulting Berlin, Berlin 201–500 employees Founded 2007 Privately Held

Readdle builds consumer-facing productivity applications (Spark, Documents, Scanner Pro, PDF Expert, Calendars) primarily for iOS, with active efforts to scale Documents to the web. The tech stack is Apple-native (Swift, SwiftUI, UIKit) paired with backend infrastructure (Node.js, NestJS, Kubernetes, AWS) and analytics tooling (Amplitude, Tableau, Sensor Tower). Current hiring is heavily weighted toward senior engineers, with projects centered on paywall optimization, system reliability under load, and a new product launch—indicating a company in controlled revenue acceleration mode rather than growth-at-all-costs.
