OpenCanvas raises $45M Series B to scale generative design API and launches CanvasFlow SDK

OpenCanvas, known for its image-to-layout generative models, closed a $45 million Series B round and simultaneously launched CanvasFlow, an SDK meant to embed OpenCanvas capabilities directly into product and design workflows.

CanvasFlow exposes the startup's multimodal models as a developer-friendly API and a local inference option for enterprises worried about IP and privacy. The SDK includes layout constraints, versioned model checkpoints, and a visual diff tool aimed at bridging design and engineering handoffs.

Company leadership says the funding will expand R&D on domain-specific generators for ecommerce, SaaS dashboards, and packaging design, and grow partnerships with Figma and Sketch plugin teams to simplify adoption.

Industry advisors welcomed the move, noting that offering both hosted and on-prem inference plus an SDK addresses a major bottleneck for designers who want generative assistance without changing their tooling stack overnight.
