About Callstack

Callstack is an AI-native engineering company. We build cross-platform products with agent-driven workflows, then help enterprise teams adopt the exact same way of working. Backed by 10+ years of React Native leadership, our work combines framework expertise with the tools and systems needed to ship at AI speed. We do that in four areas: • Engineering: We build complex React and React Native products with AI-native workflows, so teams can ship roadmap work faster, launch across platforms more efficiently, and solve hard engineering problems without trading away quality. • Infrastructure: We build the systems that let faster output become faster shipping, from agentic QA and device automation to CI/CD and observability, so delivery stays reliable as AI speed increases. • Adoption: We turn AI tools into a repeatable way of working by configuring the stack, training engineers, and measuring impact, so teams get more than experimentation and leadership gets a clearer return on AI investment. • Governance: We keep enterprise AI under control at scale with private models, tooling audits, tighter access, and smarter model routing, so teams can move faster without creating security, compliance, or cost problems. We also build specialized tooling for this new era, including Apex, our specialized model for React Native that cuts frontier-model costs, and Agent Device, which gives AI agents control over real iOS and Android apps. And we bring the community into that conversation through Agent Conf, where the future of agent-driven development gets shaped in public. This work builds on more than a decade of React Native leadership: • Core Contributors to React Native and Founding Members of the React Foundation. • 10+ years in the space and 100+ enterprise projects delivered. • Open-source software behind more than 30M monthly downloads.
