What Stonexchange does
Stonexchange is a wholesale manufacturer, importer, and distributor of natural stone finishing products, specializing in marble window sills and stone thresholds. Founded in 2005 and headquartered in Miami, Florida, the company operates an 18,000+ square foot distribution center that maintains approximately 40 containers of marble window sills and at least 50,000 door thresholds in inventory at any given time, enabling immediate shipment to dealers nationwide. The product portfolio centers on four categories: marble window sills (available in five standard stones — Travertine, Nuevo White Carrara, Crema Sahara Marfil, Absolute Black Granite, and Pure White Engineered Stone), stone thresholds (Standard Double Bevel, Single Hollywood Bevel, and Double Hollywood Bevel configurations, including ADA-compliant designs), corner soap caddies, and shower curbs.
The company's business model is wholesale-only, selling full crates (50-200 pieces depending on product type) with minimum order quantities to trade buyers. Customers include tile distributors, flooring companies, home improvement stores, flooring contractors, builders, hotel developers, residential housing developers, and architects. Stonexchange does not sell directly to homeowners and redirects consumer inquiries to retail locations. Go-to-market relies on trade show presence (Coverings, HD Americas, SURFACES, IBS, Stonexpo East), the company website (windowsills.com) with online catalog downloads, social media, and direct dealer inquiry. Special orders for custom sizes or specialty stone colors are fulfilled through the company's overseas manufacturing centers with a 10-week lead time and minimum purchase quantity requirements. The company is privately held with President Volkan Okay Yazici referenced as the senior executive; no external institutional investment, parent company, or subsidiary structure is disclosed.
