About
Virtusize is a B2B AI platform purpose-built for fashion e-commerce retailers who want to eliminate size uncertainty and its costly downstream effects. At its core is a virtual fitting room that allows shoppers to visualize how garments will fit their actual body — not just a size label — using as few as four simple inputs to minimize drop-off. The underlying AI is trained on an unprecedented dataset of 150 million orders, 30 million users, and 10 million products, enabling precision fit recommendations and deep personalization at scale. Beyond fit visualization, Virtusize offers product-level garment measurement comparison so shoppers can benchmark new items against clothes they already own. The Data Connect module lets retailers feed Virtusize's rich behavioral and sizing data back into their own marketing and product systems for smarter decisions. Integration is designed to be plug-and-play: retailers add two script tags, upload their existing size data in any format (CSV, Excel, etc.), and Virtusize's AI auto-converts and activates it. The platform is compatible with all major e-commerce stacks including Shopify, Magento, WooCommerce, and custom builds. Verified client results include up to 5× conversion rate uplift, return rate reductions above 40%, and average order value increases. Virtusize is trusted by leading global fashion brands and continues to expand its partner network, growing brand partnerships by over 50% in 2025.
