A lot of small businesses are tinkering with mobile media, especially adding Twitter. We heard recently from sales consultant Mel Taylor that Naked Pizza in New Orleans, which is backed by netpreneur Mark Cuban, is getting 15 percent of its walk-ins via Twitter.

But how can most businesses really work with mobile? That’s the challenge taken up by Ric Pratte, who has launched JitterGram, an eight-person company near Manchester, New Hampshire, dedicated to leveraging mobile’s chief advantage: just in time promotions.  “Save Money – Show The Phone” is the company’s tagline (I like it).

Pratte says JitterGram can be used to reach out to patrons and get a quick response … even that night. It’s especially good to get rid of unused inventory, ranging from hotel rooms to salon reservations. “For a whole generation, e-mail is just too painstakingly slow,” he says.

Mostly, JitterGram employs SMS text messages as its platform. But comprehensive mobile solutions can also be developed. Currently, JitterGram isn’t working directly with local businesses. Instead it is relying on local resellers, including our friends at CitySquares.com.
