The complete walkthrough showing how a 60-second car scan turns a "he-said-she-said" into court-admissible proof.

Most drivers hand over their keys with hope. They hope the valet is careful. They hope nothing happens. They take a few phone photos — just in case. Then a scratch appears. The manager points at the ticket: "We are not liable for damages." And your phone photos? "Those could be from anywhere."
"Hope is not evidence. A photo without a timestamp is not proof. What you need is a signed agreement between both parties — created in 60 seconds, verified by AI, and impossible to dispute."

Ask yourself: if a scratch appears after valet, what evidence do you have right now? A paper ticket that says "not liable"? Phone photos with no trusted timestamp? Your word against theirs?
The One Thing: A mutual digital handshake — timestamped, GPS-verified, cryptographically hashed, and confirmed by both parties — removes the argument before it starts.
Athens. Hotel valet. I got my car back with a scrape on the rear bumper. The manager pointed at the ticket. The attendant shrugged. I had photos on my phone — but they were useless. No timestamps anyone would trust. No mutual agreement. No way to prove the car was clean when I handed it over.
You snap a few photos with your phone. You hand over your keys. You hope. But in a dispute, the valet says "those photos could be from any day." And they'd be right. Your photos have no trusted timestamp. No GPS. No chain of custody. No evidence that the car was clean at that exact moment.
Result: €800 repair bill. Higher insurance premium. Zero leverage.
Then I realized: the valet has the same problem. When a customer falsely accuses them, they have no defense either. Both sides are blind. Both sides lose. The solution isn't better cameras. It's a signed agreement between both parties.
The gap: No tool existed that created mutual proof in under 60 seconds.
Open CarShake in your browser. 8 guided angles in 60 seconds. GPS-verified. SHA-256 hashed. A QR code appears. The attendant scans it with their own phone — no app needed. They tap "Confirm Condition." That tap is a digital signature. Both sides signed. Both sides protected.
Result: $0 repair bill. 30-second resolution. Court-admissible evidence.
Here's what you actually get. Not a camera app. A legal shield.
🛡️ Guarantee: If you still get charged for damage with a valid CarShake handover receipt, we pay it.

A quiet movement of drivers who refuse to pay for damage they didn't cause — and valet operators who need defense against false claims.
We are drivers who paid for scratches we didn't cause. Valet operators blamed for damage that was already there. Both sides losing the same argument — because neither had proof.
We stopped hoping the ticket would protect us. We built a system where both sides sign — and both sides are protected.
We don't measure in downloads. We measure in disputes we prevented. Every scan is a €800 scratch that never turned into an argument.
