Relativity Technologies is going after new business in the public sector.

A key target of the Cary software firm’s efforts will be the federal government. Toward that end, Relativity is expanding its management team by hiring a director of federal operations.

Relativity, which produces software that modernizes old legacy systems, has also hired a sales and consultancy firm based in Northern Virginia to help drive the federal sales effort.

Bill Ryan takes on the federal operations role, joining Relativity from Siemens where he was a vice president of marketing and strategic planning. He also is a graduate of West Point and was a Major in the U.S. Army.

Federal Solutions Group, which is based in McLean, VA, was retained to assist the sales initiative. Its emphasis is helping high-tech firms gain federal IT business.

“Relativity’s solutions for the U.S. Postal Service, U.S. Air Force, and multiple state and local governments have driven down the cost and accelerated the modernization, management, and maintenance of enterprise applications for these agencies,” said Steve Maysonave, president and CEO of Relativity, in a statement. “Our new public sector practice builds on this success, combining our demonstrated experience with focused leadership and the new partnership with Federal Solutions Group.”

The latest move is one in a series of initiatives launched by Relativity in recent months. The company closed on more than $6 million in venture capital in March and later secured $1.25 million in financing from Silicon Valley Bank.

Relativity remains in a “hiring mode,” according to Maysonave. The company has added several new customers in recent months and is improving revenues, the CEO said.

The company and its chairman/founder, Vivek Wadhwa, are embroiled in lawsuits. Wadhwa is seeking deferred compensation and repayment of loans. Relativity terminated Wadhwa in May.
