Lifebelt is a technology company from Las Vegas, NV, that is peddling a device that will make cars even safer: a box that will prevent the car from starting unless the seatbelts are being worn.

How, precisely, this box can tell if someone is sitting in a given seat on top of whether the belt is being worn isn't super well explained.

The Lifebelt box needs to be wired into a car after market but the entrepreneur promises that it's simple enough that an average person could install it. And, of course, it's patented.

Suffice it to say, all of the lives that this product could potentially save isn't enough to hook a shark and make a deal and Lifebelt eventually goes home without a partner.


According to an update that aired with the final episode of Season One, Lifebelt was being sold in Gallman Auto stories throughout Houston, TX. The entrepreneur estimated the value of the deal as being just north of $1,000,000 and projected earning as much as $10,000,000 by the end of the year.

Not bad for a deal that never scored a deal with shark but proving that the Shark Tank bump is actually a thing that can help businesses even if they never make a deal.
