ATLANTA … PerformanceIT, which sells information technology management solutions to small and mid-sized companies in various industries, says its customer base grew by 18 percent during the last three months.

New customers include Benchmark Brands, which markets high-performance foot care products, Cal-Maine Foods, a major distributor of fresh eggs, Spirit Airlines, managed care provider Syntiro Healthcare Services and optoelectric component manufacturer Terawave Communications.

The customers have hired PerformanceIT to monitor, maintain and manage their e-commerce infrastructure, databases, e-mail and other web-based platforms.

“Our strong customer growth is a clear indication that PerformanceIT’s suite of services, including our recently-released ProIT platform, is meeting the needs of small and mid-sized companies,” Vice President of Sales Andrew Kramer said in a statement. “By providing a one-stop shop, PerformanceIT enables our customers to shift their in-house resources to strategic initiatives, rather than being consumed with IT system monitoring and maintenance.”
