What Bold Metrics does
Bold Metrics is a San Francisco-based AI body data platform that builds digital twins of shoppers for apparel brands and retailers. From 4–6 simple inputs (age, height, weight, etc.), the company's proprietary machine learning models infer 50+ individual body measurements and match them against per-style garment specifications to deliver size recommendations, without requiring scans, photos or measuring tapes. The platform is underpinned by 250M+ digital twins, 12B+ body data points and 750M+ fit simulations, and is delivered through five core products: Smart Size Chart (drop-in widget), Virtual Sizer (white-label API), Virtual Tailor (made-to-measure), Apparel Insights (analytics over the body data library), and the Agentic Sizing Protocol (a protocol for AI shopping assistants). Customers include enterprise brands such as Gap, Canada Goose, Helly Hansen, Burton, New Balance, Charles Tyrwhitt, Men's Wearhouse and Vuori, as well as mid-market and made-to-measure labels (Pact, Mizzen+Main, SuitShop, Fire-Dex, Blue Delta Jeans, French Toast, Monica and Andy).
The company operates a B2B SaaS model with quote-based, multi-year enterprise contracts negotiated via "Request a Demo" flows, supplemented by a non-exclusive referral program and direct API integration into brand eCommerce stacks. Distribution combines direct enterprise sales with embedded delivery (white-labeled API, drop-in widget, and now agentic commerce integrations with Google Gemini / Universal Commerce Protocol, anchored by Gap as a launch partner). The company is incorporated in Delaware as Bold Metrics, Inc., has disclosed roughly $13M of total funding across multiple small rounds (Techstars, Right Side Capital, Tahoma Ventures, Geekdom Fund, Corsa Ventures, Elementum Ventures, Lytical Ventures, ValueStream Ventures), and closed an $8 million Series A led by Bessemer Venture Partners in May 2022.

Revenue model
- B2B SaaS platform subscriptions: Bold Metrics provides SaaS solutions (Smart Size Chart, Virtual Sizer, Virtual Tailor, Apparel Insights) to apparel brands and retailers. Revenue is generated from brand subscriptions/integrations of the AI body data platform. Customized, white-labeled deployments per brand.
- Referral / partner-sourced lead program: Non-exclusive referral program where independent "Finders" are paid gift cards ($50 per qualified meeting, $250 per closed deal, up to $600 max) for introducing customers. Drives incremental pipeline but is an indirect revenue lever, not core.
- Agentic Sizing Protocol licensing / integration: Newer protocol that lets AI shopping assistants and agentic commerce platforms consume Bold Metrics' sizing intelligence. Represents a potential usage- or integration-based revenue stream layered on top of core SaaS as the technology is adopted by Gap and other launch partners.
