Seifert e-commerce — online store built with Agência Ousar
Seifert
In partnership with Agência Ousar
Seifert — an optics and jewelry brand from Jaraguá do Sul (SC) with physical stores and national reach — needed a production e-commerce surface. Pixelize delivered the store build in partnership with Agência Ousar (ous.ar): co-delivery / white-label engineering under Ousar’s client relationship, Pixelize owning the e-commerce implementation.
E-commerce live for Seifert — catalog-to-checkout storefront delivered with Agência Ousar on seifert.com.br.

Context
Seifert combines brick-and-mortar trust in Jaraguá do Sul with a national online channel. The digital store had to carry brand credibility, product discovery, and a clear path to purchase — while the engagement ran through Agência Ousar as the marketing partner. Pixelize stepped in as the tech partner for the e-commerce build.
Challenge
- Ship a real e-commerce storefront for a multi-store retail brand — not a brochure site
- Keep catalog, product pages, and checkout coherent for national online sales
- Deliver as white-label / co-delivery with Agência Ousar without fracturing ownership
- Hand off a store the brand and agency could operate after go-live
What we shipped
E-commerce build for Seifert in partnership with Agência Ousar: storefront structure for product discovery and purchase, responsive front, and production cutover on the official domain. Pixelize owned engineering; Ousar owned the client relationship and go-to-market partnership.
