True Fit is the Fit Intelligence Layer for apparel and footwear commerce, helping retailers turn shopper uncertainty into confident purchase decisions.
Every shopping journey eventually reaches the same question: “Will this actually fit me?” For fashion shoppers, that question is the moment where they either move forward, hesitate, order multiple sizes, or leave. True Fit helps retailers resolve that moment with decision-grade fit intelligence built on nearly 20 years of real-world purchase and return outcomes.
Powered by a proprietary data foundation spanning over $616B in transactions, 60M unique active products, and 91K apparel and footwear brands, True Fit learns from what shoppers actually bought, kept, and returned, not guesses, static size charts, or generic AI inference.
As commerce shifts toward AI agents and conversational shopping, True Fit gives retailers the intelligence layer needed to move shoppers from approximation to confidence. True Fit can be activated through an out-of-the-box Fit Agent or integrated as a Fit Intelligence Layer via MCP, bringing fit expertise into PDPs, shopping agents, search, support, returns, exchanges, and broader agentic commerce experiences.
For retailers, this means higher conversion, fewer fit-related returns, fewer multi-size orders, stronger loyalty, and better shopper understanding across brands, categories, and markets.
Conversational AI engages. Decision Intelligence converts.
