OPHIR GAATHON — the physicist who taught objects to vouch for themselves
Take a bolt headed for a fighter jet, a luxury watch, a vial of cosmetics, a circuit board you would rather a foreign supplier had not quietly swapped. Ophir Gaathon's company sprinkles a thin layer of microscopic diamond particles onto it. The diamonds settle, roll, tumble, and freeze into a polymer. Where they land is pure chance, and that chance is the product.
The scatter is read like a fingerprint. Copy the object all you like; you cannot copy how a million specks of diamond happened to fall. Gaathon calls it “a fingerprint that is unique in the universe.” DUST Identity, the company he co-founded in 2018 and runs as CEO, sells that randomness as trust.
The category he reaches for is biometrics. “We're creating an identity management system for physical objects that allows us to authenticate them using tools that are very similar to biometrics,” he has said. A face has features no one chose; so does a scattering of diamond dust. The job is to read it, log it, and check it later.
What makes the pitch land in boardrooms is the price. The diamonds are not jewelry. They are industrial waste, the grit left over from cutting and grinding. “Dust is dust. It's diamond dust, but we make it at scale,” Gaathon says. On high-volume parts the marker runs to fractions of a cent. Defense-grade security, sold by the spoonful.
Diamond dust is mixed into a polymer, painted, sprayed or coated onto an object - or built into a part.
The polymer hardens. “Once the diamonds fall on the surface and that polymer cures, the diamonds are fixed” in place.
A reader captures the particles' positions and orientations - a random pattern no one designed.
The fingerprint links the physical object to its digital record, blockchain-agnostic, for the life of the part.
In 2011, Gaathon was a graduate student at Columbia University, deep in the quantum characteristics of diamonds - the kind of work aimed at sensing and computing, not supply chains. There he met Jonathan Hodges and Dirk Englund. Three physicists, one material, no business plan.
The trio later regrouped at MIT, and that is where the story bends. DARPA, the Pentagon's research arm, arrived with a blunt problem: there was no trusted way to verify the physical identity of high-value components moving through a supply chain. You order a part. Do you actually get the part you ordered?
Gaathon is candid about why that matters. “You make an assumption that the vendor will do good by you,” he has said. “Unfortunately, we've seen time and again that, either by error, economic incentive or security issues with a nation state actor, you're not necessarily going to get the components you think you're supposed to get.”
The team realized the quantum quirks they had been studying made microscopic diamonds perfect for a physical fingerprint. Before DUST Identity existed, Gaathon spent roughly seven years as CEO of a company named, fittingly, Diamond Nanotechnologies - developing the underlying material science with his future co-founders. The startup was the long tail of the lab.
DUST Identity emerged from stealth in 2018 as an MIT spin-off with DARPA support and a $2.3M seed round. The mission statement reads like a physicist trying to be poetic: to put “Trust in Things that matter now and in the future,” and to “protect and connect every thing that matters.”
The founders work from a belief that sounds more brand strategist than physicist: “authentic products tell powerful stories and build beloved brands.” Counterfeits, in that telling, do not just cost money. They corrode the story.

Led by Kleiner Perkins, with Airbus Ventures and Lockheed Martin Ventures.
Led by Castle Island Ventures - plus a left-field partnership with Oxygen Esports for authenticated collectibles.
Bars scaled to round size. Total disclosed funding: $53M+.
Partner Ilya Fushman framed the bet around “a growing trust gap between manufacturers and suppliers.”
Led the $40M round in 2023, joined by Amex Ventures and 8VC.
Aerospace and defense venture arms backed the company early - the exact buyers with the most to lose from fakes.

“Dust is dust. It's diamond dust, but we make it at scale.”
“We're creating an identity management system for physical objects... using tools that are very similar to biometrics.”
“The diamond dust allows us to create a unique identity on the physical object that remains permanent to that physical object - and it's very easy to apply.”
