Private early access for Shopify fashion stores
Stop letting the wrong size come back.
FitGuide AI recommends the right size before checkout—without asking shoppers to find a tape measure. Fashion e-commerce return rates run 20–40%, wrong size is the leading reason, and processing one return can cost roughly $15.

The signal
Merchants say it best.
Apparel operators are already describing the same three problems: shoppers skip size charts, sizing language is inconsistent, and legacy tools get expensive to leave.
“Sizing returns are part and parcel of apparel, usually 20 to 40 percent... Most customers don't measure, they just buy their usual size.”
Shopify Community merchant
“Under 15% of shoppers actually look at size charts... ‘Our M fits like a Zara L’ converts way better than a measurement table nobody reads.”
Apparel store owner, public forum
“We used to pay around $5 to $7 per month. Now we are being charged around $150 per month... once you have created 100+ size charts, switching is extremely time consuming.”

Questions
The short version.
Will FitGuide work with my theme?
The goal is a one-click Shopify app block that works with modern Online Store 2.0 themes. Founding merchants will get hands-on install support while we validate compatibility.
What happens to shopper data?
FitGuide is being designed to use only the information needed to make a size recommendation. The pilot will document what is collected, how it is used and how merchants can export or remove it.
How is this different from a size chart?
A size chart asks shoppers to interpret measurements. FitGuide is designed to give one personalized recommendation using three quick inputs, product sizing and return feedback.
When does it launch?
FitGuide is currently a thesis test in private early access—not a live public app. We will invite a small group of apparel merchants into the first concierge pilot before opening more broadly.
What do founding members get?
Early input on the product, hands-on onboarding, priority pilot access and the right to keep the published founding rate for life while the account stays active.
