“A virtual fitting room facilitates buying clothes on e-commerce sites”
Original headline: “Provador virtual facilita compra de roupas no e-commerce”
The first time the magazine covered Sizebay, in the product's first year: a virtual fitting room that makes buying clothes online less of a gamble.
What the piece reports
The piece is live on the magazine's site, bylined Adriano Lira. It names Janderson and Patricia as the couple running the company, quotes Janderson explaining how the algorithm infers a size from height, weight and age, and records the timeline: the idea in 2013, angel investment in 2014, and the fitting room launching in August 2015.
Read now, the product it describes is almost quaint. Height, weight, age, then the chest, waist and hip modelled on a drawing you could adjust; exact measurements optional; and if you did not know your own, the tool would print you a measuring tape. The differentiator he gives the magazine is the one that stayed true for a decade: because every manufacturer sizes a small, a medium and a large differently, the fitting room adapts to each site's own charts, which he contrasts with the foreign competitors then leading that market.
The reason to keep this piece, though, is Patricia. It is the only piece in this record where she is a source, and what she reports is not a feature. The stores using the tool, she tells the magazine, saw the number of calls to their call centres fall along with the number of exchanged online orders. An operations person's result, before anyone was measuring conversion lift.
There is one more thing worth noticing, ten years later. Asked what came next, Janderson told the magazine he wanted to build a clothing search engine, where a shopper could look for a garment and get results across different stores. The company shipped search by image in 2025.
“[Opinion] What makes companies invest in e-commerce stores?”
An opinion column by Janderson, not about him: his argument for why companies were moving into e-commerce. It ran in one of the state's most traditional newspapers, founded in 1923.
“AI promises consumers a smart wardrobe”
Valor Economico on how AI is reaching the wardrobe, with Janderson among the voices it interviewed. He is quoted on the shift from recommending a size to helping someone get dressed, and on what a company owes a person whose photograph it processes.
“Sizebay: virtual fitting room grows more than 40% in Europe with technology made in Brazil”
The company reports 41% revenue growth in Europe and 35% in Brazil over the year, 65 countries and 1,200 virtual stores, with the new AI personalization platform at roughly 20% of quarterly new recurring revenue. Janderson is quoted as co-founder. The figures are the company’s claims as reported.
