Bellevue-based Nintex announced Tuesday morning that former Seahawks football player and Hall of Famer Steve Largent and former Coinstar CEO Brian Turner will join its board of directors.

“As we lay the groundwork for the future expansion of our company and continue to execute against our vision of revolutionizing the way organizations do business, deepening our leadership bench is crucial,” John Burton, Nintex CEO, said in a statement. “Brian and Steve are dynamic leaders and their proven business and leadership expertise will be invaluable as Nintex strengthens its leadership position in workflow automation.”

The company has seen more than 30 percent compounded-growth over the past six years, with $50 million in sales last year. It’s Seattle office grew from 15 employees to 50 in the past year. Burton told 425 Business that the company is interested in strategic acquisitions to help sustain the rate of growth.

“We’re growing very rapidly and we’re obviously very focused on maintaining high financial integrity, with the potential, certainly not something that we’re committed to at this point, but the potential of building a public offering,” Burton said.

Burton was looking for people who were not investors or members of the management team to help govern the direction of the company, and approached Turner and Largent to join the board of directors,

“We couldn’t find anybody with a better network, better set of business experiences on a national level, even international, than Steve Largent,” Burton said. “I think he’s known for his integrity, his intelligence, and at the same time he’s got the admiration and respect of people in the international level.”

Turner has financial background in public and private companies as former CEO of Coinstar and RealNetworks. He led the IPOs of BSQUARE and Radisys Corporation.

“Nintex’s strong product line and command in the workflow automation arena put it on a solid path for continued growth,” Turner said in a statement. “I’m excited to serve on the Nintex board of directors and look forward to working with John and the rest of the board to support the company as it brings the power of workflow to more organizations.”

Nintex was started in Melbourne, Australia, in 2006 and received “significant investment from private equity firms that are well-known in the tech industry,” Burton said. The company currently has 6,000 customers in 90 countries, and is in the final stages of settling its headquarters in Bellevue.

“Time zone challenges out of Australia are not small, and we’re a global company so this is the most central location and the largest market at the same time,” Burton said.
