To help companies adopt the next way software is built.
Boilerplate
AI-native engineering for cross-platform products
Callstack builds cross-platform products with AI-native engineering and helps enterprise teams bring the same way of working into their own delivery. We work across React and React Native, agent-driven infrastructure, AI adoption, and governance.
We have worked in the React Native ecosystem since 2016 as Core Contributors to React Native and Founding Members of the React Foundation. Our open-source projects are used in 50M+ downloads each month. Alongside client work, we build tools for agentic development, including Apex, our specialized React Native model, and Agent Device, which gives AI agents control of real iOS and Android apps. We also host Agent Conf, where engineers discuss how software delivery is changing.
