CHARLOTTE, N.C. — NuTech Solutions, a developer of artificial intelligence software that helps companies be more efficient, has a new chief executive officer.

Veteran investor and entrepreneur Bud Whitmeyer took over as CEO, the Charlotte-based company announced Friday. He replaces Tom Wilson, who was named chairman of the board.

Whitmeyer had served as chief operating officer for the privately held company.

The CEO change is the second for NuTech since 2003 when founding CEO Matt Michalewicz was forced out in September of 2003. Matt and his father, Zbigniew who also was a company co-founder, were bought out. The two started a new business in Australia and recently published a book titled “Winning Credibility: A Guide For Building A Business From Rags To Riches”.

Whitmeyer is a general partner at Research Triangle Ventures, a venture capital investment group, and is a member of Charlotte Angel Partners. He has worked as CEO and chief technical officer of a number of portfolio companies. Earlier in his career he spent 11 years at SAS.

Whitmeyer joined NuTech’s board a year ago and also assumed the COO post.

“It is a privilege to assume responsibility for leading an impressive team of science and software professionals around the world,” Whitmeyer said in a statement. “NuTech Solutions has an unmatched history of innovating science for business, and we tackle some of the most complex problems facing companies in today’s highly-competitive economic environment.

“We will continue to improve our capability to deliver leading-edge scientific software for data mining, modeling and simulation, and optimization to our current and future customers,” he added.

Wilson replaces Robert MacDonald as board chairman.

“The Board and I recognize the opportunity to best scale the business through accelerated product growth and improved software development quality and efficiency,” Wilson said. “Given these initiatives, it is an opportune time to transition to new leadership to accelerate the company’s transformation. While we have stabilized the Company, improved our customer focus, and built a solid list of Fortune 500 customers who are using our software daily to bring value to their businesses, I believe Bud’s technical background and experience working with emerging software companies offers a new set of skills which can take NuTech to the next level of growth.”

In January, NuTech spun off a new company, VGO Associates that is based in Boston.
