👋 Editor's Note
Every parking lot is a graveyard of lost intent.
People don’t browse used cars only at home.
They spot them in offices, apartments, malls, cafés.
They slow down. They look twice. Then… nothing.
Because there is no way to act in that moment.
The internet optimized car buying for sofas and screens.
Real demand happens standing next to the car.
That gap is pure waste.
The car is the listing. Scan it to buy
🦄 The Idea Drop: Scan & Sell
The Problem:
Used car platforms are built like catalogs.
Search, filters, comparisons, cold leads.
But real intent is physical and emotional.
You see a car you like. You imagine owning it.
Then friction kills the impulse.
Dealers insert themselves.
Marketplaces delay response.
Trust erodes before a conversation even starts.
By the time a buyer goes home to search, the moment is gone.
The Solution:
Turn every parked car into a live deal.
A unique barcode sticker sits on the windshield.
Scan it and you instantly see the truth:
What car it is
What the owner wants
How to reach them
How to make an offer
No browsing. No intermediaries. No pretending.
Curiosity turns into conversation in seconds.The Features

🚀 MVP Blueprint
Concept
We are testing offline intent, not automotive perfection.
1. Tech Stack
Flutter for fast cross-platform shipping
Firebase Auth and Firestore for speed and simplicity
Dynamic QR or barcode generation per vehicle
Stripe for optional premium listings
Built to ship in weeks, not impress engineers.
2. Core Features
Create a car profile and generate a unique barcode
Public scan page with car info and offer CTA
Private chat triggered only by real scans
That scan is the magic moment.
3. Validation Plan & Estimates
Week 1: Seller flow, barcode generation, scan page
Week 2: Offer flow, chat, basic notifications
Week 3: Pilot with 50 real cars in one city
Week 4: Measure scan to offer conversion
Budget: Minimal. Hosting, SMS, notifications
Success Metric: 25 percent of scans convert to offers

🧠 Founder Lesson: Intent Lives Offline
Most platforms chase traffic.
Winners capture moments.
The highest intent is not when someone is scrolling.
It is when they are standing next to the thing they want.
This idea wins because it intercepts desire at its peak.
No SEO can beat that.
⚡ Quick Tips
Tool: Firebase Dynamic Links for frictionless scans
Competitor: Traditional classifieds that never see parking lots
Book: Hooked by Nir Eyal, but read it backwards
This idea does not compete with marketplaces.
It bypasses them.
Cars are already advertising themselves.
This just gives them a voice.
Bye Bye.
