About BodyWHAT
BodyWHAT is a passion project. The goal has always been to build the best physique-tracking app there could be: one that measures your body from a photo as accurately as possible, shows you how it changes, and coaches you towards the body you want.
The founder
BodyWHAT was founded by Charles-Elie Labroy, a data scientist and machine-learning engineer based in Paris. He trained as a statistician at ENSAE ParisTech, one of France's leading engineering schools for statistics.
He first built BodyWHAT in 2014, as founder and CTO: estimating body fat from a single photo with computer vision, long before AI apps were everywhere. BodyWHAT went through the Startup42 accelerator, and the site grew to over 100,000 registered users. He then spent five years as an Algorithms Data Scientist at Criteo, followed by two years as a Product Data Scientist at Meta.
In 2024 he came back to BodyWHAT to rebuild it from scratch with today's deep learning: BodyWHAT's own vision models, trained and run on its own servers, and Rob, an AI coach that knows your scans.
Why BodyWHAT
Measuring your body properly usually means a DEXA scan, calipers or a smart scale, and many apps today just send your photo to a general-purpose chatbot and parrot its imprecise guess. The idea behind BodyWHAT is something anyone can use with a phone, that is honest about its accuracy, and that respects your privacy.
