Bold Metrics

Bold Metrics is a San Francisco-based software-as-a-service company that operates an AI body data platform for apparel brands and retailers. Its technology asks shoppers four to six simple questions and uses proprietary machine learning models to estimate more than 50 individual body measurements, creating a "digital twin" of each shopper without requiring a photo scan, body scanner or measuring tape. The digital twin is combined with a brand's product specifications, design guidelines and the shopper's stated fit and style preferences to generate size recommendations on a style-by-style basis.

The product line consists of Smart Size Chart, a fit-preference-aware size chart; Virtual Sizer, an API-based size recommendation solution; Virtual Tailor, aimed at custom clothiers and tailors needing customer body measurements; Apparel Insights, an analytics product that surfaces body data, purchase and returns insights for design, merchandising, eCommerce and supply chain decisions; and the Agentic Sizing Protocol, which exposes sizing recommendations to AI shopping agents. Stated capability areas include agentic commerce, body data, design, eCommerce and returns, and the company also describes applicability beyond apparel to health and wellness, digital health and insurance.

The company positions its platform around three outcomes for brands — increasing conversion through fit confidence, raising average order value via personalization, and reducing fit-related returns and size bracketing — and markets sustainability benefits from lower return volumes and reduced wasteful production.

Founding story

Co-founder and CEO Daina Burnes was inspired by her family's Master Tailoring craft and the idea that traditional tailoring methods could be adapted for eCommerce, leading the team to build algorithms that estimate body measurements from a small number of data inputs.

Business model

SaaS licensing of fit and sizing software to apparel brands and retailers, delivered through website widgets and APIs with onboarding and integration support; an additional Virtual Tailor offering targets custom clothiers and tailors, and a referral program and partner program are listed on the site.

Subscription/SaaS solutions sold to retailers and brands.

Traction

Reported platform scale of over 250 million digital twins, 12 billion body data points and 750 million fit simulations. Published results from customer engagements cite an average 4x increase in conversion rate, a 22% average increase in order value and a 17% average reduction in fit-related returns, with an 18% average reduction in fit-related returns for shoppers who engage its solutions and follow the recommended size.

Latest developments

The company has launched an Agentic Sizing Protocol enabling AI shopping agents to return size recommendations, and announced a 'Find Your Fit' schoolwear implementation with French Toast and a performance menswear fit collaboration with Mizzen+Main.
