E-Learning Providers Seattle, Washington 11–50 employees Founded 2011 Privately Held

Pocket Prep delivers test preparation across iOS and Android for professional certifications, built on a TypeScript/Node.js backend with native Swift and Kotlin frontends. The tech stack reveals a mobile-first, platform-agnostic approach; the shift toward Go and Rust for server infrastructure suggests they're addressing database performance and production stability issues at scale. A lean org (11–50 employees, mostly engineering) shipping exam readiness features and AI benchmarking points to an execution-focused team optimizing for retention rather than headcount.
