Got a call from them, seems pretty well thought out. For the car owner, there's no up front costs nor monthly fees; they will do all the insurance paper work for you and their company will pay for the insurance policy (your regular policy will be the same but any accidents during the course of rental will be covered by the policy that they will sign up and send you). The car owner does not need to pay for the insurance. They will also install the telemetrics device as well for free. The only cost is they will take 30% of payment from the rental proceeds; so if you end up without any rentals, no fees on you. A reimbursement of at $1.5 HKD per km will be made for gasoline as well (if it doesn't cover your gas guzzler, just increase the hourly/daily rate).
Interesting option for those who are looking to rent cars in HK. They're working on an app to be rolled out in Feb where the renter will download an app where they can get a key access code. Once they have paid for the rental, the renter can use their smart phone with the access code to unlock the car door with the telemetrics device. The car owner can leave the physical key inside the car so the renter can just return it to the same parking spot and lock it back up with the smart phone app/telementrics device. Cool stuff.
They said cars are only the start for them, motorcycles are being considered now.
It's a great story I think of a bunch of young people getting money support from HK gov and private investors. Too often in HK, young people's business ideas gets shot down by cynical old folks before they even take off. Good for them.
Disclosure - I am NOT involved with their business; but you may be able to rent my Audi Allroad 2.7T in the Saikung/Ma On Shan area through them soon LOL
