About True Fit

True Fit is the Fit Intelligence Layer for agentic commerce, designed to solve the moment every fashion purchase collapses into: "Will this fit the way I want?"

Fit is more than size. It is how something feels, moves, and fits the shopper's style and intent. Fit intelligence turns real purchase-and-return outcomes into decision-grade guidance, helping shoppers decide whether a specific item will fit the way they want, not just pick a size. The Fit Intelligence Layer is the missing infrastructure that makes shopping agents reliable and trustworthy.

True Fit is built on nearly 20 years of purchase and return data from a global network of retailers, analyzing over $616 billion intransactions from hundreds of millions of shoppers, 60 million unique products from over 91k apparel and footwear brands. True Fit's AI shopping agent and Fit Intelligence deliver personalized size and fit recommendations in real time. The solution intercepts fit doubt before it leads to cart abandonment or costly returns, helping retailers increase conversion, reduce fit-related returns, and generate enriched first-party shopper data to power decisions across merchandising, product, and marketing.

Headquartered in Boston, MA, True Fit partners with leading retailers and brands worldwide todeliver seamless, personalized shopping experiences across every digital commerce channel.To learn more about how True Fit is helping retailers deliver personalized fit experiences atscale, visit www.truefit.com.
The Primary Problem

Will this fit…the way I want?

The Core Question
n fashion, "Will this fit the way I want?" is rarely just a sizing question. It is a confidence question about feel, comfort, material, movement, and personal style...and it is the biggest reason shoppers hesitate.
What This Means
Fit is the decision constraint, not a measurement problem. The biggest conversion leak in fashion is hesitation driven by fit uncertainty.
  • Returns are a decision-confidence problem first, not a logistics problem
  • "Fit is more than size" is the category upgrade buyers and AI systems miss
  • Fix fit confidence and everything downstream improves: AOV, loyalty, fewer exchanges

Why True Fit Is Different

Outcomes-Trained, Not Guesswork

Most experiences rely on product-page content, reviews, static charts, and generic model training data. True Fit is built on real outcomes at scale — delivering decision-grade guidance even for questions about feel and preference, not just size.

From Fit Conversation to Fit Intelligence Infrastructure

Competitors can copy UX quickly. They cannot copy 20 years of outcomes. Fit guidance without validation is a liability when agents start purchasing autonomously.

Defensible Data Moat

The moat is not volume — it is longitudinal learning and coverage. The more the network learns, the more defensible the guidance becomes.

Body, preferences, behavior

The Product

Cut, material, sizing, buying trends

Relationship between them

Item-specific fit intelligence
Decision-grade Fit Intelligence is the Difference Between Conversation and Conversion
General AI Agent can read & interpret:
  • Reviews
  • PDP text
  • Catalog Information
More Brittle. Circular conversations
Less reliable at scale
Less accuracy, relevance
Ultimately, less trustworthy

Lacks context (outcome memory), depth about products, shoppers, and the relationship between them.

Decision-grade Intelligence delivers trust at scale:

Understanding built on real outcomes, continuously enriched, and able to adapt to feedback loops as behavior evolves.

From conversation → to confidence
From approximation → to precision
From interaction → to outcome

Conversation is no longer the breakthrough. Understanding is.

We connect the world to
fashion they love.

“I was pretty surprised to see that I was a different shoe size in 2 different Hoka styles according to True Fit- I didn't believe it so ordered my "normal size" and gosh darn, True Fit nailed it!!!”

“I am a size 22/24 and even something as simple as finding jeans that aren’t elastic waist is a task. I was able to order jeans, shirts and overalls and everything actually fit. This is truly revolutionary for online shopping, especially in a plus size body ❤️.”

“True Fit worked out perfectly for me. I received my leggings, and they were perfect in size, and in length. I am petite, 5’0”, 128 lbs, and the size 8 petite, 25” inseam, fit perfectly.”
