Expo Raises $45M Series B to Streamline Mobile App Development via AI Agent

San Francisco based Expo, the prominent framework for React Native development, announced a $45 million Series B funding round today. Led by growth equity firm Georgian, the investment aims to streamline the lifecycle of building apps for iOS, Android, and the web. This capital injection arrives as the company looks to bridge the gap between initial software concepts and production-ready mobile applications.

A cornerstone of this expansion is the launch of Expo Agent, an AI-assisted development tool now available in public beta. Powered by Anthropic's Claude Code, the agent serves as a virtual solutions engineer that understands platform-specific patterns and configurations. Unlike typical AI tools that produce web wrappers, this system generates genuine native code, including SwiftUI and Jetpack Compose, to ensure high performance.

The funding will be directed toward enhancing the core platform with faster builds and deeper native integrations. Expo plans to aggressively develop its agentic tooling, helping teams identify issues before they reach production and recommending optimal deployment configurations. This strategy addresses the fragmentation in a mobile market that generates over $500 billion annually according to Business of Apps.

To lead this new era of AI-native development, Expo has appointed Seth Webster as Chief Developer Evangelist. Webster, who previously served as the Head of React at Meta, will focus on driving adoption across global developer communities and enterprise teams. His transition highlights the growing importance of declarative frameworks in an environment where AI excels at generating structured interface code.

The platform already powers major digital services, including the New York MTA's real-time transit updates. Using Expo infrastructure, the MTA's team can deploy critical patches in under 90 seconds, bypassing traditional app store delays. This level of reliability has helped Expo reach nearly 4 million weekly downloads and a community of over 3 million developers worldwide.
