Mosaic Design raises $9M to launch MotionGrid, a prototyping engine for micro-interactions

Design · 4 min read

MotionGrid lets designers define interactions as parameterized components, test them against device profiles, and export production-ready code snippets for web and native platforms. Mosaic claims the engine captures motion intent—timing curves, easing, and gesture thresholds—and produces cross-platform artifacts that developers can drop into applications.

The funding, led by PixelBridge, will support SDK expansion and an enterprise orchestration layer that manages animation libraries, versioning, and performance budgets. MotionGrid also includes a visual regression harness that compares motion outputs across releases to surface regressions.

Design teams piloting MotionGrid reported smoother handoffs and reduced friction when specifying interaction behavior. Mosaic plans to add AI-assisted motion suggestions based on user engagement patterns and to expand integration with design tools and code review processes.
