Nimble raises $30M for micro-interaction library and UX performance analytics

Tech · 3 min read

Nimble today announced a $30 million Series A led by Index Ventures to grow its micro-interaction library and UX analytics platform. Nimble provides pre-built, performance-optimized micro-interactions—like hover states, loading skeletons, and tactile feedback—implemented as lightweight, accessible web components.

Beyond components, Nimble's analytics layer measures interaction performance across real users, surfacing where micro-interactions contribute to perceived latency or layout shifts. Teams can A/B test animation durations and easing curves against engagement metrics without touching native code.

The company will invest the new capital into building design-system integrations (Figma-to-NPM), native SDKs for mobile platforms, and enterprise features including tokenized animation governance for large product organizations.
