MirrorLab Raises $16M to Launch LiveProof — Real-time UI QA and visual regression for design teams

Tech · 4 min read

MirrorLab secured $16 million in a Series A to bring LiveProof, a product that captures design and runtime UIs to detect drift between design files and live applications. The funding round was led by Studio Ventures and comes amid rising demand for continuous UI quality assurance.

LiveProof integrates with CI/CD pipelines and design platforms, generating deterministic snapshots and pixel-aware diffs while surfacing semantic differences in component behavior. The tool emphasizes collaborative triage workflows between designers and engineers to accelerate fixes.

MirrorLab plans to offer on-premises and cloud-hosted options for regulated customers and will expand to support mobile visual testing and accessibility regression detection. The new capital will help scale backend infrastructure and expand partnerships with testing vendors.
