What Sergio does

Sergio K. (legal entity SLKS COMERCIO DE ARTIGOS DE MODA LTDA, CNPJ 09.028.217/0004-27) is a Brazilian premium men's fashion retailer founded in 2004 and headquartered in São Paulo. The company sells menswear across nine top-level product categories — Camisetas, Camisas, Polos, Calças, Bermudas, Casacos e Jaquetas, Calçados, Acessórios, and Outlet — plus a parallel Kids sub-line spanning the same categories, organized around proprietary fabric lines including 'Tech - Não Amassa' (wrinkle-resistant), 'Camisa Power / Tech Power Premium', 'Bermuda Tech', and 'Malha Power'. The catalog depth is substantial, with 264 SKUs in the Outlet alone and 71 footwear SKUs across loafers, sneakers, dress shoes, and Chelsea boots.

The commerce platform is built on VTEX (with the Sergio K. theme and VTEX File Manager for media assets), supported by Getnet for antifraud transaction screening with a 24-hour manual review SLA, Genius Returns for post-purchase exchanges, Correios for nationwide Sedex/PAC fulfillment (2-6 business days), and WhatsApp Business for the Personal Shopper buying-assistance channel. Fulfillment is multi-modal: same-day Super Expressa motoboy delivery within 5km of Jardim Paulista in São Paulo capital, free Correios shipping above R$ 600 nationwide, and free in-store pickup within 6 business days.

The business model is primarily direct-to-consumer e-commerce supplemented by own physical stores ('Nossas Lojas'), authorized resellers recruited via the 'Seja um Revendedor' program, and third-party marketplace listings. Revenue is driven by one-time apparel sales augmented by a 15% site-wide cashback loyalty program (30-day validity, 30% cart-discount cap), a BEMVINDO 10% first-purchase coupon, a 5% Pix payment discount, free shipping thresholds, and a parallel Outlet channel offering up to 50% off. Customer segments span Brazilian premium menswear consumers, parents shopping the Kids line, authorized resellers and marketplace sellers (B2B indirect channel), and outlet value-seeking premium shoppers. The entity operates exclusively in Brazil with no public-market listing, disclosed funding rounds, or management team bios in the source material.

Core offering

Sergio K. designs, produces, and sells its own branded premium men's fashion apparel and footwear — shirts, polos, t-shirts, pants, bermudas, outerwear, shoes, and accessories — directly to Brazilian consumers via a VTEX-powered e-commerce storefront (sergiok.com.br), own physical stores, and a network of authorized resellers and marketplace listings. The assortment is anchored by proprietary Tech (non-iron) and Malha Power fabric lines, supported by a 15% cashback loyalty program, BEMVINDO first-purchase coupon, and Kids sub-line for family expansion.

Product overview

Sergio K. operates a single unified direct-to-consumer e-commerce storefront — not a multi-product SaaS platform — under the legal entity SLKS COMERCIO DE ARTIGOS DE MODA LTDA (CNPJ 09.028.217/0004-27), branded "Sergio K. | Moda Masculina Premium | Loja Oficial". The catalog is organized into nine top-level product categories — Camisetas (T-shirts), Camisas (Shirts), Polos, Calças (Pants), Bermudas (Shorts), Casacos e Jaquetas (Coats & Jackets), Calçados (Footwear), Acessórios (Accessories), and Outlet — together with rotating seasonal "NEW IN" collections such as the Winter 26 collection. Each category is further broken down into named sub-lines (e.g., Tech Power Premium shirts, Calça Power pants, Bermuda Tech shorts, Polo Pima, Polo Resort, Moletom, Tricot, Loafers, Shorts de Praia) and a parallel Kids line. The storefront layers promotional mechanics on top of the catalog — a 15% cashback program, a BEMVINDO 10% first-purchase coupon, 5% off for Pix payments, free shipping (FRETE GRÁTIS) thresholds, an in-store pickup (RETIRE GRÁTIS) option, and a Personal Shopper WhatsApp support channel. The site is built on the VTEX commerce platform with we.digi as the digital partner.
