Twelve years ago, Granite Telecommunications LLC started out in an office over a Quincy bridal salon. Today, it's a $1 billion, 1,200-employee provider of voice, data, networking, and other communications services. The company said Monday that it has surpassed $1 billion in annualized revenue.
It uses the copper wiring in traditional networks to offer cost-effective services to business customers whose locations span multiple states. Previously, such customers needed to work with multiple service providers. Granite says it can offer one-stop shopping.
