Expo raises $45M Series B and launches Expo Agent to close the gap from idea to production-ready mobile apps. Apr 16, 2026, 10:30 ET Led by Georgian, new funding and appointment of Seth Webster as Chief Developer Evangelist to accelerate Expo's mission to make every mobile app built to ship SAN FRANCISCO, April 16, 2026 /PRNewswire/ - Expo, the open-source platform powering React Native development for millions of developers, today announced $45 million in Series B funding led by Georgian. The funding round, which also includes participation from Leadout Capital, A.Capital Ventures and Red Swan Ventures will accelerate Expo's vision of shortening the path from idea to production. Alongside the raise, Expo launched Expo Agent, a forward deployed mobile expert that gives enterprise teams the equivalent of an embedded solutions engineer and welcomed Seth Webster as Chief Developer Evangelist. According to Business of Apps, mobile applications generate more than $500B annually, yet the tooling supporting them has historically been fragmented and operationally complex. Founded in 2015 by early Facebook engineers and Quora co-founder Charlie Cheever, along with James Ide, Expo simplifies the entire lifecycle of building applications for iOS, Android, and the web, with a mission to be "everything you need to build apps." Expo already powers apps used by hundreds of millions of people, from startups to Fortune 500 companies, including Phantom, Pizza Hut, MTA and PrizePicks. With close to 4 million weekly downloads and a community of over 3 million developers, Expo has proven that removing friction doesn't mean lowering quality standards. With the addition of agentic app development using Expo Agent, builders can now go from a simple idea to a fully functioning mobile app running on a device in minutes, without complex setup or native expertise, dramatically compressing development timelines while maintaining production-grade reliability. "Expo has been the foundation of the MTA's digital services team for over five years, and this year, we're going deeper, launching our new Subway & Bus app on the platform," said Will Fisher, Head of Digital at MTA. "Our 20-person team keeps 3 million daily riders connected to real-time transit updates across Metro-North, Long Island Rail Road, and New York City subway and bus systems. When a critical issue hits, we can identify, patch, and deploy a fix in under 90 seconds using Expo's over-the-air updates. When you're operating at the scale of New York's transit system, you don't experiment with your infrastructure, you double down on a technology partner you never have to worry about." The investment will accelerate development of Expo's core platform with faster builds, deeper native integrations, and an improved developer experience, while advancing agentic tooling for AI-assisted development, starting with Expo Agent, now available in public beta. Representing Expo's first step into agentic programming, Expo Agent is designed to help humans and AI build truly native, production-ready apps together, understanding the platform-specific patterns, configurations, and constraints of modern mobile development. Expo Agent is like a forward deployed engineer that can scaffold projects with production-ready architecture, debug complex native integrations, recommend optimal deployment configurations, and identify issues before they reach production. "The problem with agentic app development is that business critical apps are not making it to production," said Charlie Cheever, co-founder of Expo. "That is the problem we are positioned to solve at Expo. We built the infrastructure for mobile apps and we can bake that infrastructure into Expo Agent. Our mission is to give every builder - whether they're a solo founder, an enterprise team, or someone working alongside AI agents - the infrastructure to ship production-grade apps that scale and succeed." To help accelerate ecosystem growth and cement Expo's role as the default path from idea to production, the company has welcomed Seth Webster as Chief Developer Evangelist. Seth will lead Expo's platform narrative in an AI-native development future, drive adoption across startups, enterprises, and global developer communities, and deepen strategic partnerships with infrastructure partners, platform stakeholders, and device manufacturers. He will work closely with product, engineering, and executive leadership to align roadmap decisions with ecosystem needs and long-term platform durability. "We're at a moment where the React Native ecosystem is expanding faster than ever, fueled by AI-assisted development, new enterprise entrants, and a global community pushing the boundaries of what's possible on mobile," said Seth. "From solo builders to enterprise teams scaling for millions of users, my focus is on making sure that every developer who picks up Expo finds a platform that meets them where they are and grows with them. Expo has earned deep trust in this community. This role is about widening that path and making sure the best infrastructure for mobile is also the most accessible." The funding enables Expo to support a growing universe of builders, from engineers shipping at scale and founders testing new ideas to enterprise teams accelerating development without sacrificing reliability, as well as new entrants working alongside AI, while strengthening enterprise-grade performance, security, and compliance for apps at scale. "Expo has reached an inflection point, evolving from a popular open-source framework into an increasingly important infrastructure layer for cross-platform app development," said Emily Walsh, Lead Investor at Georgian. "By collapsing the fragmented mobile toolchain and capitalizing on the surge of AI-assisted coding, we believe Expo is democratizing how applications are built and maintained at scale. We have been inspired by the team's decade-long commitment to the developer experience and we are proud to partner with them as they work to make app development more accessible and reliable for enterprises and developers."

Expo, the developer of a popular open-source tool for building cross-platform applications, has raised $45 million in funding. The company offers a framework that accelerates React Native projects, Meta's enhanced version of the React library used for building web services and mobile applications. React Native, open-sourced by Meta in 2015, extends the original React library to enable development of both iOS and Android apps alongside web services. Expo's framework simplifies and speeds up this development process by organising interface code into manageable modules and improving loading times. The funding will support further development of Expo's tools for cross-platform application development.

Session Replay for Expo: monitoring managed workflow apps. Track Feature Adoption with Vexo: Enhance Debugging in Expo Without Ejecting March 5, 2026 Incorporating runtime analytics into Expo has shown to improve real-time diagnostics for 50% of developers. Vexo takes this a step further by seamlessly integrating with EAS Build and Over-the-Air (OTA) workflows to provide powerful session replay capabilities, all without the need to eject your app. Whether you're troubleshooting or optimizing user flows, Vexo enables you to capture and review every interaction, error, and network request within Expo. With this integration, you can enhance debugging efficiency, improve app stability, and streamline your development process, all while maintaining the simplicity and flexibility of Expo's managed workflow. Integrating Vexo with Expo managed workflow for better debugging. Vexo stands out by fully integrating with the Expo managed workflow, allowing developers to gain full visibility into user behavior and errors without needing to modify the app. Unlike other tools, Vexo helps developers monitor and debug their apps without having to eject them. The integration is simple and uses a standard npm/yarn dependency along with a runtime initializer, ensuring that there's no need for native project file modifications. You can run the app directly inside the Expo managed workflow, simplifying the development process. Key integration highlights: * No native code modifications: Vexo works seamlessly without altering iOS or Android native files. * Simple setup: Integrate Vexo via npm/yarn and a runtime initializer, with no native project changes required. * Expo support: Works with Expo on both iOS and Android for real-time testing. * EAS Build and OTA compatibility: Integrates with EAS Build and EAS Update (OTA), allowing you to ship monitoring updates without needing to resubmit to App Store or Play Store. Expo documentation confirms that Expo runs on both iOS and Android, and EAS provides cloud build and OTA update tooling, making the integration process even more efficient. Session Replay: capturing critical data in Expo. These categories map directly to the data developers use to reproduce bugs: gestures, screen navigation, XHR/fetch calls, and runtime exceptions. You can view replays recorded on Expo devices immediately after a session ends, because the SDK records events in-memory and uploads compressed payloads when connectivity is available. How Vexo reduces MTTR and improves developer productivity. Session Replay shortens mean time to repair by replacing speculative debugging with visual reproduction. Developers observe the exact UI state, network calls, and console output in a single view. Visual context transforms hours of log triangulation into minutes of inspection. Since Vexo ties each replay to build metadata and OTA channel, teams can isolate regressions to specific EAS Build profiles or OTA releases. This makes it easy to roll back or patch the exact channel that introduced the issue. Filtering by build ID and OTA channel removes guesswork when multiple release channels are active. Events and metrics you can track with Vexo in Expo. Vexo captures standard telemetry out of the box: uncaught exceptions, handled errors, custom tracked events, navigation events, network requests, and console output - covering at least six actionable event types used in debugging workflows. Each event is timestamped and correlated to the visual replay timeline. Custom events and user properties are supported, enabling product metrics such as feature adoption, funnel drop-off points, and session duration to be combined with replay for qualitative analysis. Combining quantitative funnels with replay reduces ambiguity when interpreting why users drop from flows. Comparing analytics options for Expo.
