Marmi

What Marmi does

Marmi Stone, LLC (operating as Marmi Natural Stone) is a vertically integrated, US-headquartered supplier of premium natural stone serving luxury residential and commercial construction. The company traces its origins to Marmonil, a Cairo-based natural stone quarrying and distribution business founded in the 1970s, and established its US presence in Atlanta (later relocating headquarters to Norcross, Georgia). Its core offering centers on an extensive global inventory of slabs — marble, travertine, limestone, onyx, and quartzite sourced from quarries in Italy, Portugal, Spain, Mexico, and Morocco — sold alongside two curated Collections (Architecture & Landscape tiles and Classics interior stones) and the Marmi Editions line of designed furnishings spanning Mantels, Bath, Kitchen, and Entertaining categories.

Commercially, Marmi goes beyond material supply by integrating custom services (shop drawings, project management, engineering and value-engineering support, shipping and logistics) and fabrication services (layouts, detailing, metals and stone inlay, vein and book matching, custom fluming and edge details, and installation). Pricing is quote-based and not publicly disclosed, with price groupings ranging from standard to ultra-premium ($ to $$$$$). The company generates revenue primarily through one-time slab and tile transactions and professional services tied to custom fabrication and installation, and it monetizes Marmi Editions as designed product sales.

Marmi goes to market through direct sales via three US showroom locations (Norcross, GA headquarters; New York; Florida), an online inquiry system, and design-community relationships. Its primary customer segments are architects, interior designers, and high-net-worth homeowners, with secondary segments including general contractors, landscape architects, and developers. Notable projects and brand collaborations span Harrison Design and Tish Mills (Charleston kitchen), Stonehill Thailand (Bangkok clubhouse and estate), House of Matouk (NYC flagship), and Lalique (NYC Maison d'artiste). The company operates as a privately held LLC under founding-family ownership, led by CEO Magd Riad.

Direct peers

• ABC Stone: US-based importer and fabricator of natural stone slabs serving architects and designers from New York; comparable in vertical integration, slab inventory breadth, and designer-focused sales motion to Marmi.
• Stone Source: Curated natural stone and tile supplier with showrooms in major US design markets (NYC, DC, Boston, Chicago, LA); the closest head-to-head competitor to Marmi in the design-spec slab and architectural tile segment.
• Marble & Granite, Inc. US natural stone importer and fabricator with showroom distribution serving residential and commercial fabricators and designers; comparable to Marmi on slab supply, fabrication, and customer base.
• Walker Zanger: Premium tile and natural stone boutique serving architects, designers, and luxury residential projects with curated slabs, mosaics, and architectural tile — directly comparable to Marmi's Classics and Architecture & Landscape collections.
• Antolini Luigi & C. Italian natural-stone supplier offering an extensive global quarry-sourced slab and tile inventory with a luxury-grade positioning; directly comparable to Marmi in curated stone selection and designer-channel sales.

Broad incumbents

• MSI (M S International): Largest US distributor of natural stone, quartz, and tile with a broad showroom-and-distribution model; competes with Marmi on slab selection and dealer reach but at a much wider, less luxury-focused SKU breadth.
• Cosentino (Dekton, Silestone): Global manufacturer of engineered quartz (Silestone) and ultra-compact porcelain (Dekton) surfaces sold through a designer-focused channel; competes for the same kitchen/bath specifications as Marmi's slabs and Editions line, but in engineered rather than natural stone.
• Caesarstone: Global engineered quartz surface manufacturer with a strong residential-kitchen go-to-market; an alternative-substrate competitor for the same designer/contractor specification that drives Marmi's slab volumes.

Regional players

• Tile Shop Holdings: Multi-store US retailer of tile, stone, and related installation supplies targeting consumers and pros; overlaps with Marmi's tile collections at lower price tiers and DIY/customer-builder positioning.

Others

• HenryBuilt (partnership adjacent): Premium custom kitchen and storage systems maker that integrates stone surfaces via partnerships; included as an ecosystem partner rather than direct competitor, but useful for understanding Marmi's go-to-market adjacency in the designer-kitchen channel.
