Stone Engineering
Equity Group

Stone Engineering Equity Group, LLC (SEEG) is a Delaware-formed special purpose vehicle (SPV) created exclusively to pool accredited investor capital into a single concentrated position in OK Stone Engineering, Inc. — an operational U.S. engineered quartz manufacturer based in Garland, Texas. SEEG is not a diversified fund; it is a direct, single-asset investment vehicle structured to give investors clean, institutional-grade exposure to one company.

The Managing Member is Oren Klaff, a nationally recognized capital markets professional, best-selling author, and founder with over $1 billion in financing outcomes. Oren has sole management authority over the SPV.

OK Stone manufactures engineered quartz using three Breton-licensed technologies unavailable to most U.S. competitors: Bioquartz — a silica-free manufacturing process that eliminates the crystalline silica dust linked to silicosis, an incurable occupational lung disease currently under emergency regulatory action in California and scrutiny at the federal level; Chromia® — high-resolution full-body printing that replicates exotic natural stone aesthetics at industrial scale; and Kreos Plus — exclusive molding technology for ultra-thin slab profiles and complex patterns. Together, these technologies produce a product that is safer, more aesthetically advanced, and approximately 10% less costly to manufacture than conventional quartz.

The U.S. countertop market grew 67% between 2016 and 2021, with engineered stone becoming the most-used countertop material in the country. By 2026, engineered quartz demand for countertop applications alone is projected to reach 404 million sq. ft. — nearly double the demand for natural stone. Yet domestic manufacturing capacity covers only a fraction of that demand, with over 200 million sq. ft. currently imported annually through fragile supply chains. OK Stone is positioned to capture a meaningful share of this gap with domestically produced, next-generation product.

Prospective investors must review the full Private Placement Memorandum, LLC Agreement, and Subscription Agreement; complete accredited investor verification; and submit a fully executed subscription package to the Managing Member. Funds are wired only after written acceptance. For access to the data room or to speak directly with the team, use the contact options on this site.

OK Stone Engineering currently operates a 170,000 sq. ft. manufacturing facility in Garland, Texas in the Dallas-Fort Worth metropolitan area. The facility is fully operational and producing product today using Breton-licensed Chromia® technology. This is not a pre-revenue startup; the company generates revenue from its existing manufacturing line.

SEEG investors receive a level of access and transparency that is uncommon in private placements. This includes regular investor calls (held weekly), periodic updates on OK Stone's operations and milestones, annual K-1 tax documents, and distribution notices when applicable. Investors also have direct access to the leadership team and are invited to participate in shareholder events including the Stone 300 — a closed-door gathering for select investors — and the broader shareholder conference community. Multiple investors have cited this transparency and access as a defining feature of the investment.

To date, over 400 investors have committed more than $40 million in total funds. The current offering through the SPV is raising up to $5,000,000 in Class A Units. The deal's credibility and the leadership team's strong track record are reflected by its validation from a large and growing investor community, which includes experienced real estate principals, private equity operators, and business owners.
