What GEMx AG does
GEMx AG is a Swiss Aktiengesellschaft (AG) headquartered at Bundesstrasse 5, 6300 Zug, Switzerland, operating the EmGEMx platform—a blockchain-based tokenization infrastructure for fractional co-ownership of physical emeralds. The company issues EmCH tokens (ERC-20 standard) on Avalanche and Ethereum networks (mainnet contract address 0xA445bA2c94d9dE6bFd13F2fe4165E738C4330710), where each token represents fractional ownership of vault-stored physical emeralds on a 1:1 basis. The platform employs a multi-layer verification architecture spanning emerald sourcing (IGI INEX with Brazilian mine access), bonded warehouse logistics (IGI Inex), independent quality certification (Gübelin Gem Lab, WGI), secure vault storage (BTV SGS at Switzerland Freeport, Zürich Airport), monthly third-party audits (Grant Thornton), blockchain proof-of-reserve verification (Chainlink oracle), smart contract security audits (Hacken), token minting authorization (Fireblocks), and institutional digital custody (Zodia Custody). The Emerald Standard Unit (ESU) provides a proprietary monthly re-evaluation benchmark anchored to a Standard Portfolio (initial value USD 1M, quality grades 4-8, weight range 1ct-2ct), while the Main Portfolio allows open-ended composition valued through this benchmark. The firm monetizes through transaction fees on tokenized co-ownership shares and recurring asset management services, targeting six institutional segments—regional banks and family offices (primary), plus digital-asset lenders, ESG-mandated funds, insurance companies, and wealth managers—via a 5-step direct-sales engagement flow requiring KYC/AML verification through Sumsub, subscription agreements, and optional physical vault visits before token delivery. The core leadership team comprises CEO & Co-Founder Paul Pöltner, CMO & Co-Founder Emanuel Stadler, Head of Technology Armin Reiter, and Head of Product Michael Gartner, supported by a four-member advisory board.

GEMx AG competitors and assessment
Company assessmentDirect peers
- AcreTrader: AcreTrader fractionalizes farmland ownership for accredited investors through a regulated platform with similar investor onboarding (KYC/AML, due diligence packages) and reporting infrastructure. Comparable alternative-asset fractional ownership model applied to a different physical asset class.
- Maecenas: Maecenas is a blockchain-based fine art fractional ownership and auction platform. Comparable as an early-stage direct peer applying tokenization to fractional ownership of illiquid luxury physical assets for institutional and accredited investors.
- Diamond Standard: Diamond Standard tokenizes physical diamonds for institutional and accredited investors via a similar blockchain-based fractional ownership structure. Directly comparable as the closest analogue in tokenized gemstones, addressing the same market gap (illiquid, inaccessible physical luxury assets) with the same technology stack.
- RealT: RealT enables fractional ownership of income-producing real estate via blockchain tokens with similar mechanics: physical asset custody, regulatory compliance, investor dashboards, and KYC onboarding. Highly comparable business model applied to real estate rather than gemstones.
- Masterworks: Masterworks fractionalizes blue-chip artwork for retail and accredited investors, offering shares that trade on a secondary marketplace. Comparable in providing institutional access to previously inaccessible alternative physical assets through a regulated fractional ownership structure.
Broad incumbents
- Ondo Finance: Ondo Finance is a leading tokenized real-world asset platform focused initially on tokenized US Treasuries and money market funds. A broad incumbent in the RWA tokenization space that could expand into alternative asset categories like gemstones.
- 21Shares: 21Shares is one of the largest issuers of crypto exchange-traded products (ETPs) globally, with a track record of bringing institutional-grade regulated crypto products to traditional finance channels. Comparable as a broad incumbent bridging traditional assets with blockchain distribution.
- Securitize: Securitize is a leading institutional tokenization platform providing infrastructure for issuing and managing digital asset securities. Comparable as a broad incumbent offering the underlying tokenization rails that GEMx uses, and a potential competitor for tokenized gemstone offerings.
- Paxos: Paxos is a regulated blockchain infrastructure platform offering tokenization, custody, and brokerage services for institutional clients. Comparable as an incumbent offering similar enterprise-grade infrastructure (custody, token issuance, regulatory compliance) used by GEMx and competing for institutional tokenization mandates.
Emerging players
- Backed Finance: Backed Finance issues tokenized securities tracking traditional assets (ETNs) on blockchain rails with similar regulatory and custody infrastructure. Comparable emerging player applying blockchain to institutional-grade asset fractionalization in regulated European markets.
