Expo Raises $45 Million Series B to Accelerate React Native Development

Expo React Native platform raises $45 million Series B funding 2026

Expo, the popular open-source platform for building cross-platform React Native apps, has closed a $45 million Series B funding round. The investment will be used to expand Expo's enterprise offerings, improve the developer experience, and deepen integration with AI-powered coding tools as demand for cross-platform mobile development continues to grow.

What Expo Does and Why It Matters

Expo provides a managed workflow for React Native development, abstracting much of the complexity of native iOS and Android setup. Millions of developers use Expo to build production apps for both platforms from a single JavaScript codebase. The platform has seen increased adoption as companies look to reduce mobile development costs without sacrificing app quality. Major apps built on Expo include Shopify's mobile storefront tools and several top-charting consumer apps.

How the $45 Million Will Be Used

The funding will primarily go toward expanding Expo's cloud build service (EAS Build), improving over-the-air update infrastructure, and launching new AI-assisted development features. The company plans to hire across engineering and developer relations roles. Notably, Expo is investing heavily in tooling that works alongside AI coding assistants, recognizing that a growing percentage of its code is being written or generated with AI help.

The React Native Ecosystem in 2026

React Native remains one of the most widely-used cross-platform mobile frameworks, competing with Flutter from Google and emerging web-based approaches. The framework received significant performance improvements in 2024 through its new architecture rewrite, which Expo has fully adopted. With the rise of AI coding tools fluent in JavaScript and TypeScript, React Native development has become even more accessible to teams of all sizes.

The Bottom Line

Expo's $45 million raise reflects sustained investor confidence in cross-platform mobile development tooling. As AI makes it easier to write React Native code, platforms like Expo that handle the deployment, testing, and distribution complexity become more valuable — not less. The investment positions Expo to capture a larger share of the growing market for managed mobile development infrastructure.
