Bold Metrics

Bold Metrics is an AI body data platform for the apparel and fashion industry that uses digital-twin technology to power apparel fit and sizing. From just 4-6 simple body-data inputs it predicts 50+ individual body measurements with tailor-level accuracy, without photos, scanning, or measuring tapes. Its products - Smart Size Chart, Virtual Sizer, Virtual Tailor, Apparel Insights, and the Agentic Sizing Protocol - help brands reduce returns, lift conversion, and increase average order value with personalized size recommendations. The Agentic Sizing Protocol exposes this capability to AI shopping agents while keeping retailer API credentials off the agent and out of any LLM. Bold Metrics has processed 250M+ digital twins and 12B+ body-data points. Backed by Bessemer Venture Partners and Techstars. This profile is maintained in the API Evangelist network; Bold Metrics publishes no public API documentation - integration is gated behind a demo/partner engagement.

Bold Metrics is profiled on the APIs.io network. Tagged areas include Company, Vertical Software, Apparel, Fashion, and Sizing.

Bold Metrics’ developer surface includes engineering blog, support, and 4 more developer resources.
