There is no verification
process for what's in our clothes.

In the United States there is no mandatory chemical disclosure, no health-grade screening, and no supply chain traceability standard for textiles. A brand can sell a garment treated with PFAS compounds or heavy metals with zero legal obligation to disclose it. The science has known about these risks for years. The infrastructure to do something about it has never existed.

$92B
US materials and brands exported to EU annually — all requiring verified chemical documentation by 2027
10,000+
Individual PFAS compounds in circulation — standard testing detects fewer than 60

"The regulation mandates disclosure — but no standardized verification methodology exists in the EU or the US. The compliance obligation exists on both sides of the Atlantic. The infrastructure does not exist on either side."

OKO is where fashion supply chains
go to become provable.

We apply health-grade chemical analysis to fashion materials — the same scientific rigor used in biomedical research, now applied to what goes onto the body through clothing. Every material on our platform is independently verified for chemical safety and regulatory compliance, automatically.

01
Verified
What's in your fabric, proven — not assumed, not self-reported. OKO applies scientific rigor to material composition that the fashion industry has never had access to.
02
Compliant
EU Digital Product Passport compliance, automated before the 2027 mandate forces a scramble. Defensible documentation your brand can stand behind.
03
Trusted
Every verified material earns an OKO badge — a signal of transparency that brands and suppliers can stand behind with confidence.

Three tiers of verification.
One standard of truth.

OKO's verification framework meets brands and suppliers where they are — from foundational documentation through the highest standard of scientific analysis available. Every tier builds on the last. Every verified material makes the platform stronger.

Tier 01
OKO Documented
Your materials, documented and verified. OKO reviews your supplier documentation and generates a structured compliance report — automatically, without the consultant.
Material documentation review
Regulatory compliance check
Compliance gap report

Tier 02
OKO DPP-Ready
Your compliance, verified and defensible. Full EU Digital Product Passport documentation plus physical material screening — auditable by any regulator, anywhere.

Tier 03
OKO Verified
Your materials, proven at a scientific level. The highest standard of chemical verification available — the same rigor applied to what goes into a patient's body, now applied to what goes onto yours.
Full chemical safety verification

The regulatory clock
is already running.

Three converging forces are making chemical transparency in fashion non-optional. The question is no longer whether the industry will be held accountable — it's whether brands will be ready when it happens.

2026
EU Ban on Destruction of Unsold Textiles
Brands can no longer destroy unsold inventory. Chemical composition verification becomes essential for responsible material recovery and resale.
2027
EU Digital Product Passport — Mandatory for Textiles
Every textile sold in EU markets requires verified chemical documentation. $92 billion of US exports are affected. The infrastructure to comply does not yet exist.
2030
EU PFAS Ban — All Consumer Textiles
All PFAS compounds banned from consumer textiles across EU markets. Brands without verified supply chains will be locked out of the world's largest fashion market.

Martirosova
Founder & CEO, Of Known Origin, Inc.

I spent 15 years at Memorial Sloan Kettering Cancer Center studying how chemical exposure and metabolic dysregulation drive disease at the molecular level. When I started researching what's in the clothes we wear every day, I discovered something that stopped me cold — there is no mandatory verification process for any of it. Not in the US. Not anywhere.

OKO is the infrastructure I built because it didn't exist. The same rigor applied to what goes into a patient's body, now applied to what goes onto every body through clothing.
