Stone Mart

What Stone Mart does

Stone Mart is a privately held wholesale supplier of natural stone and engineered surface slabs founded around 2008 and headquartered in the Midwest United States. The company distributes granite, marble, dolomite, quartzite, soapstone, porcelain, and semi-precious stones, maintaining an inventory of approximately 6,500 slabs across four physical showrooms in Columbus-West (OH), Columbus-East (OH), Cincinnati/Hamilton (OH), and Indianapolis (IN). Stone Mart serves two primary customer segments — homeowners undertaking renovation or new construction projects, and interior designers and contractors sourcing materials for client projects — and operates a wholesale model in which customers select slabs in-showroom and Stone Mart coordinates delivery directly to the customer's chosen fabricator for cutting and installation; pricing is not publicly disclosed and is set through the fabricator relationship.

The company's core product offering spans seven material categories plus a premium Galleria of Stone Jewels collection, with engineered surfaces sourced through distribution partnerships with Quantra, COMPAC, Santamargherita, Optra, and Laminam. Complementary accessory categories include sinks, kitchen and bathroom fixtures (Kraus), kitchen sinks (Blanco), and surface care products. Stone Mart has no public API, no mobile app, and no software-as-a-service offering; an Online Visualizer tool and a blog serve as the digital top-of-funnel for showroom visits.

The business is founder/management-owned, led by CEO Yash and COO Samantha, with a Branch Manager at the Cincinnati location, a Marketing Manager (Kaelyn Van Camp), and additional team members. The company is a member of the Natural Stone Institute and ASID. Revenue is not publicly disclosed, no institutional investors or parent holding company have been identified, and there are no acquisition, IPO, or restructuring signals in the available data.

Others

• Laminam: Italian manufacturer of large-format porcelain slabs. Currently a Stone Mart supplier partner but also operates its own global distribution and showroom channels, making it an adjacent strategic peer.

Broad incumbents

• Arizona Tile: West-coast based slab and tile distributor that has expanded nationally. Comparable wholesale slab distribution plus showroom business in natural stone, quartz, and porcelain.
• MSI (MS International): Largest U.S. distributor of natural stone, quartz, and porcelain slabs with nationwide showroom coverage. Directly comparable wholesale-distribution model and product categories, but at much greater geographic scale than Stone Mart.
• Bedrosians Tile & Stone: National tile and stone distributor with extensive showroom network serving homeowners and contractors. Operates in the same stone-surface categories and wholesale-plus-showroom model as Stone Mart.
• Cosentino: Global manufacturer of Silestone quartz and other engineered surfaces, with its own U.S. distribution centers and showrooms. Competitor at the brand level whose products may also be stocked by Stone Mart.
• Daltile: One of the largest U.S. tile and stone manufacturers/distributors. Overlaps with Stone Mart in slab and tile categories but operates as a much larger vertically integrated incumbent.

Emerging players

• Cambria: U.S.-based engineered quartz surface manufacturer with company-owned showrooms. A potential upstream brand and channel competitor to Stone Mart's quartz offering.
• Caesarstone: Global engineered quartz manufacturer with U.S. distribution. Indirectly comparable as a supplier-brand competing for shelf space inside distributors like Stone Mart.

Direct peers

• Triton Stone Group: Wholesale distributor of natural stone slabs with showroom locations across the Southeast and Mid-Atlantic. Highly comparable wholesale slab selection model serving fabricators and homeowners.
• Marble & Granite Inc: Regional natural stone and engineered surface distributor operating showrooms and wholesale slab sales — closely aligned with Stone Mart's business model, though concentrated in the Northeast U.S.
