Helium Tech Stack

AI-powered paywall generation and testing for mobile apps

Software Development San Francisco, California 2–10 employees Privately Held

Helium automates paywall design and A/B testing for consumer mobile apps using an AI experience-generation platform. The stack reveals a mobile-first architecture (iOS, React Native, Flutter, Expo) paired with analytics (Amplitude, Segment) and monetization tools (RevenueCat, Stripe), while backend infrastructure (Go, ClickHouse, Fly.io) supports ML training pipelines. Pain points around scaling data systems and ML infrastructure suggest the core product is moving from rule-based paywall generation toward learned optimization models.
