This is a web site, its a phone number (877-U-Be-My-DD), it has apps (free for all devices).
The service has a couple levels of accommodation. There is the Personal Driver service where you schedule an evening with a driver who meets you, then drives your car anywhere you want, as long as you want, then returns you and gives back your keys. In Cleveland that will run you about $17.50 per hour.
They also offer Pick-Up service, which is just that. You realize you're drunk, you call them, two drivers show up. One drives you home in your car, the other follows. This level costs $25 + $3.45 per mile.
The drivers are background checked and insured. If you're thinking about this for New Year's Eve, you're probably better to make an appointment today as wait times for a pick-up tomorrow night will likely be long.
