Design · 4 min read

SketchFlow’s platform combines vector editing, component libraries, and a live preview engine that syncs interactions to a companion mobile tester app. The company emphasized low-latency collaboration: multiple designers can edit constraints and transitions simultaneously while stakeholders leave time-coded annotations.

Beyond editing, SketchFlow integrates moderated usability testing sessions and automatic session transcripts with heatmaps of interaction friction. Key selling points include native Figma and Adobe XD importers plus a version-controlled design system that enforces component tokens and accessibility checks.

The $25 million seed is led by Horizon Ventures and will fund product expansion, deeper design-system features, and enterprise access controls. The company said it will roll out SSO, audit logs, and offline sync in the coming quarters to target mid-market design organizations.
