Automotive / Real Estate / Equipment Rental
Marketplace Platform with Verified Sellers
Connect buyers with sellers they can trust: every seller proven with the chip in their ID, every listing reviewed by a person.
Built and running on MiAuto.ec, our used-car marketplace in Ecuador.
The Business Challenge
On open marketplaces, listing is free and anonymous, so a fake ad costs nothing
and buyers stop trusting every seller, the honest ones included.
Current Pain Points:
- Anonymous Sellers: Anyone can list with a borrowed ID number, because nobody checks it
- Recycled Photos: Pictures uploaded from a gallery can come from another listing, or another country
- Fake Listings: A hundred fake ads cost nothing to create, and they appear faster than moderation can remove them
- Disappearing Accounts: By the time a buyer complains, the listing and the account are gone
- Scattered Listings: Posted on several third-party platforms, each one managed separately
- No Brand Control: Your listings look like everyone else's, right next to your competitors'
What Success Looks Like:
- Every seller proves their identity before a listing reaches review
- Photos taken in the app, with plates and faces hidden automatically
- Every listing reviewed by a person, and every rejection explained
- Buyers save a search and get an alert when a match appears
- Direct contact with the verified seller, no intermediary
- Your own brand, your own data, your own marketplace
Our Solution: A Marketplace Built on Verified Identity
Native iOS and Android apps for sellers, a web portal for sellers, moderators and administrators,
and a fast public site: the same building blocks that run MiAuto.ec.
Core Features
Verified Sellers
Each seller reads the chip in their ID or passport with ID Protekt, passes a liveness check and a 1:1 match before their listing reaches review
Photos Taken in the App
The app's own camera, no gallery upload; plates and faces are found and hidden before publishing, and ads shot entirely in the app earn a verified-photos badge
Human Moderation
Every listing reviewed against a fixed checklist before it goes live; a rejection always comes with its reasons
Search & Saved Alerts
Filters built for your market (for cars: make, model, body type, province) and an alert when a saved search finds a match
Seller Apps & Portal
The whole seller journey on iOS and Android: sign in with an email code, verify, photograph, describe, send for review
Paid Listings & Invoices
No charge before identity is proven; every paid listing comes with an SRI-authorized electronic invoice, on the ISM Faktura engine
Proven on MiAuto.ec, Adaptable to Your Market
