Tello, an online service that lets users rate specific employees and businesses based on customer service, announced it is launching its website, mobile Web app, and iPhone app today at TechCrunch Disrupt in San Francisco.

Users on Tello, Instead of writing a detailed review through a site like Yelp, simply give a thumbs up or a thumbs down based on the service delivered by a business or a specific employee. Users can also provide a brief description to explain their vote.

“Tello is more like [posting on Twitter], it takes thirty seconds or less,” said Joe Beninato, CEO and cofounder of Tello. “You can’t do an immediate rating on Yelp and it’s more like a multi-paragraph blogging platform.”

Users can also scout out the best employees to work with ahead of time to avoid a bad customer service experience. Tello provides customer reaction data to businesses in the hope that they will encourage employees to provide better service and reward employees that consistently get good reviews on Tello.

The app is available as either an iPhone app or an HTML5 app for mobile phones, but Tello plans to roll out a number of apps for the other marketplaces over the next couple of months, including the Android marketplace and others.

Tello was founded in February earlier this year and has raised $1 million in funding. The iPhone app is available on the app store now, and the website should be up and running in the next couple of hours, Beninato said.
