Next big thing is...

AI

We're building AI-powered tools and intelligent automation for the next generation of mobile applications.

Tooling

React Native is being adopted by more and more companies. We're building tools to make that transition easier.

Speed

React Native is already fast, but we believe there's still room to push performance even further.

Research

As a group of innovators that works with bleeding-edge technologies, we often encounter problems that haven't been solved yet.

Focus

These four pillars are our sweet spot. And yes, they happen to make a beautiful 2x2 grid.

Artifical Intelligence

From AI-powered CLIs to performance optimizations, here's what keeps us busy in the React Native ecosystem.

Performance

There's always room for improvement. We're always looking for ways to make React Native faster and more efficient.

Developer Experience

Cross-platform development is great. We want to make you even more productive by bringing new languages to the React Native ecosystem.

New Platforms

React Native is a "learn once, write anywhere" framework. We're working on new platforms to keep that promise.

Team

Fluent in code, though we might need a dictionary for human.
