"Fake listings don't just hurt buyers. They end careers. We'll fix that."
The resale boom is real. But fake listings cost platforms trust, chargebacks, and buyers who never come back. Human authenticators can't scale. ThreadTag can — analyzing every listing in seconds, every time.
Built for platforms and brands. Designed to integrate in hours, not quarters. Your listing data never trains our models.
Everything your buyers need to buy
ThreadTag delivers three scores with every analysis — built for platforms that can't afford to guess.
40+ authentication markers analyzed across every submission: stitching density, label typography, hardware composition, material response. Trained on 200M+ verified samples — every brand, every tier.
A consistent, unbiased grade for every item. No more "seller says excellent" — buyers get objective scoring on fabric integrity, hardware function, and wear patterns. Every listing comparable.
Carbon footprint calculated and surfaced on every listing. Buyers who care can see the real impact of their purchase — not a vague pledge, but a calculated number. Differentiate on what matters.
How it works

ThreadTag scans for authentication markers, condition issues, and sustainability signals. Runs in under 3 seconds.
Auth badge, condition grade, and sustainability score are baked into the listing. Buyers see everything upfront.
