The new company will operate as WBB, employ more than 500 employees and expects to generate more than $130 million in revenue.
The merger follows a major investment in WBB by the private equity firm Lake Capital, which made an initial investment in NetStar-1 in 2007.
WBB President and CEO William McMullen will hold both titles at the combined company.
Former NetStar-1 President and CEO Kevin Rowe will assume the chairman role.
McMullen said the merger opens growth opportunities for the new WBB in the company’s target markets and positions the new company to bid on prime contracts.
Rowe said the merger extends Netstar-1’s initiative to focus exclusively on providing management consulting services to federal clients.
NetStar-1 divested its commercial sales and technology solutions divisions in 2010.
The new company will offer program management and consulting services to federal customers including the U.S. Office of Personnel Management, the Veterans Health Administration and the departments of Defense, Homeland Security and Justice.
The companies also said they are looking to work with other government contractors.
KippsDeSanto & Co. was the exclusive financial adviser to WBB.
