About WAIR

An AI-powered size and fit recommendation platform for apparel e-commerce. It uses a 3D body scan dataset to provide personalized size guidance, reduce return rates, and offer actionable insights for inventory planning and technical design.

WAIR is a specialized fit technology platform designed to solve the sizing uncertainty that plagues apparel e-commerce. By leveraging a massive dataset of 3D body scans, WAIR provides a 'Body Intelligence' layer that helps brands move beyond static size charts. The platform offers two primary value propositions: a consumer-facing size recommendation widget that boosts conversion and reduces returns, and a backend intelligence hub that provides operations, marketing, and technical design teams with anatomical data. This data allows brands to align their inventory depth with the actual body types of their shoppers and validate their grading rules against real-world morphotypes. Integration is straightforward via a lightweight JavaScript snippet, with native support for major platforms like Shopify, BigCommerce, and Salesforce Commerce Cloud. While the platform is highly effective for apparel retailers looking to reduce return overhead, it is a specialized tool focused on the fashion industry rather than a general-purpose analytics suite.
