You know those buzzers that big restaurants use to tell people that their table is ready? Well, they'll be obsolete in a few years if Stephanie Harris and Roderick Frizzelle, the co-founders of iBuzzn, have their way. They're building a tool that lets restaurants just text you when your table is ready, and developing a customer relationship management tool for food businesses around that. Harris is the company's visionary, as Frizelle likes to call her, while he's developing the actual software. They're working out of the city of Durham's Startup Stampede offices while they prepare to beta the app.
