Proof 8
Verifying the physical world
We build the technology that proves ownership, provenance, and authenticity for the world's most valuable physical assets. From premium spirits to luxury goods, we bring absolute transparency to complex supply chains.
The vision
The future of physical assets is digital
The way we track, trade, and trust physical goods is fundamentally changing. Regulatory mandates like the EU's digital product passports and the FDA's traceability requirements under FSMA 204 are accelerating a shift toward total transparency. GS1 is pushing all retailers to adopt QR-based identification by 2027. This is not a distant future; it is happening now.
Proof 8 provides the foundational technology to meet this future. We ensure that every high-value asset, whether a cask of whisky, a luxury watch, a piece of fine art, or a designer garment, has a secure, verifiable digital identity that proves exactly what it is and who owns it.
Spirits and fine wine
Where we started. Verified ownership and full provenance for every cask, barrel, and bottle across the production lifecycle.
Luxury goods and watches
Authenticated ownership for high-value items where provenance and fraud prevention are essential to maintaining trust and value.
Fashion and art
Digital identity for physical creations, connecting makers to collectors with transparent, tamper-proof records of authenticity.
Proven in spirits
The modern operating system for distilleries and warehouses
We started by solving one of the most complex operational challenges in manufacturing: the production and maturation of premium spirits. Today,Proof 8 gives producers total control from grain to glass, replacing fragmented systems and spreadsheets with a single source of truth for production, maturation, bottling, compliance, and cost visibility.
Our Digital Deeds technology provides secure, transferable digital ownership for every cask, allowing clients and investors to verify ownership in seconds with complete, fraud-proof audit trails.
