On Tuesday, Ron Kupferman announced the sale of his Raleigh software company Peopleclick for an eye-popping $100 million in cash.

A few miles north, his sons were busy running their smaller company, which sells spreadsheet software to accountants and others.

"I'm 36 and my brother is 40," said Spencer Kupferman, vice president of corporate affairs at Global Software. "We're young guys, we love what we do and we haven't accomplished our goals here."

He didn't reject the possibility of selling Global Software if the right offer came along, but the brothers for now are focused on attracting new customers.

"We get inquiries all the time from investment bankers, private investors and other software companies," he said. "The reality is we're going to come to work with our lunch pails and our hard hats on and see where the chips fall."

The company last month moved to cushier offices off Atlantic Avenue in North Raleigh. The 13,000 square-foot space is about the same as Global Software's previous offices, but Spencer Kupferman said they were able to negotiate a better deal with a new landlord, Highwoods Properties of Raleigh. He declined to comment on specific terms.
