Build buyer trust on every listing.
Give your marketplace verified ownership infrastructure. Every listing shows a certificate, every sale triggers an automatic transfer and every fraud signal surfaces before a transaction completes.
How it works
Ownership verification built into every transaction
Ownich integrates with your marketplace platform to add verified ownership to every listing — without changing your core buying and selling flow.
Seller lists with their certificate
When a seller lists an item, they attach their Ownich ownership certificate. The listing displays the verified ownership badge automatically.
Buyer verifies before purchase
Buyers can scan the QR code or view the certificate directly on the listing — seeing the full ownership history and certificate integrity signals before they pay.
Sale completes, ownership transfers
When the transaction completes, Ownich initiates the ownership transfer. The buyer accepts and the certificate updates — no manual steps required.
Marketplace gets the data
Every transfer feeds your marketplace analytics — price trends, category performance, transfer velocity and fraud signals across your entire platform.
Benefits
What marketplaces get with Ownich
Reduce fraud, increase buyer confidence and add verified ownership infrastructure to your platform — without rebuilding from scratch.
Verified listings
Every listing on your marketplace can display a verified ownership certificate — giving buyers confidence that the item is genuine and the seller is the rightful owner.
Fraud detection signals
Ownich's trust engine surfaces fraud signals on every certificate — duplicate listings, stolen item flags and ownership chain anomalies — before a transaction completes.
Seamless transfer infrastructure
When a sale completes, ownership transfers automatically. No manual paperwork, no disputes about who owns what — the certificate updates in real time.
Ownership history on every item
Buyers can see the full ownership chain for any listed item — who owned it, when they bought it and what it sold for previously. Transparency that builds trust.
Market price intelligence
Ownich aggregates transfer data across your marketplace to surface real-time price indices — helping buyers and sellers price with confidence.
Higher conversion rates
Verified listings convert better. Buyers are more likely to complete a purchase when they can verify the item's certificate integrity and ownership history before paying.

Ownich is designed for marketplaces where buyers and sellers trade items with real value — and where trust, certificate integrity and fraud prevention are competitive advantages.

Everything included
Everything a marketplace needs to add verified ownership.
Ownich's marketplace plan includes all the tools to verify listings, automate transfers and surface fraud signals — integrated into your platform via API.
Asset appraisal
Verified valuations that make every listing more credible.
Ownich brings certified appraisal data into your marketplace. Every listing with an Ownich certificate shows a verified valuation — giving buyers a trusted price reference and giving sellers a stronger negotiating position.
Valuation displayed on every listing
When a seller lists an item with an Ownich certificate, the verified valuation is shown alongside the listing price — giving buyers an instant credibility signal.
Price history from the certificate
Buyers can see what the item originally sold for, what it has been appraised at over time and how the current asking price compares — all from the certificate.
Reduce pricing disputes
A certified valuation on the certificate gives both parties a neutral reference point. Fewer disputes, faster negotiations and higher transaction completion rates.
Aggregate market price intelligence
Ownich surfaces real-time price indices from transfer data across your marketplace — helping you build category price guides and market trend reports.
Trusted price reference for buyers
A certified valuation removes the guesswork. Buyers know they're paying a fair price — and are more likely to complete the transaction.
Stronger seller positioning
Sellers with a verified appraisal on their certificate can justify their asking price with evidence — reducing lowball offers and time-wasting negotiations.
Platform-level price analytics
Aggregate appraisal and transfer data across your marketplace to build category price indices, trend reports and market intelligence products.
