The person
Understand the person wearing it.
Height, weight, age: a few answers, no tape measure.
WeeFizz, data that connects people and garments: size recommendation, workwear allocation, product images and virtual try-on
Workwear allocation
The right size for every employee.
No more fitting sessions or exchanges: every employee gets the right size first time.
Online store
Help your customers choose the right size.
“M or L?”: settle the hesitation on the product page, before it turns into a return.
AI studio
A new dimension for your visuals.
Your garments worn and styled, true to the product, with no photo shoot.
Virtual try-on
Help your customers see themselves in it.
Your customer sees the garment worn on their own photo, before buying.
Our approach
Data that connects people and garments.
A size goes wrong when you overlook the person or the garment. We analyse both.
The garment
Know every product.
Every size chart is built in exactly as it is.
The data
Recommend, then manage.
Sizes by site and by product, no spreadsheets.
Our solutions
Four solutions. One data foundation.
Two to find the right size. Two to show the garment.

An M doesn't mean the same thing from one brand to the next.
The same M varies from brand to brand. We start from each product's size chart.
