By Light Professional IT Services last week acquired Phacil Inc. in a deal that expands its offerings to the federal government.

Terms of the deal, which was completed March 15, were not disclosed. Both companies have about 600 employees.

By Light, which is based in Northern Virginia, provides program management, systems design and engineering, satellite communications, information assurance, rapid prototyping, federal healthcare and other services for classified and unclassified government networks. Some of the company’s customers include the Navy, Departments of Agriculture, Justice, State and Veterans Affairs, and the National Security Agency.

Phacil, which is also based in Northern Virginia, provides mission-focused technology solutions to the Defense Department and federal civilian customers. Its core capabilities are in software services, systems engineering, integration and operations, cyber security, cloud and managed services, service desk support, and artificial intelligence.

“We are thrilled to acquire Phacil, which has a proven track record of excellent service and growth,” Bob Donahue, CEO and found of By Light, said in a statement. “Its diversified IT capabilities across a wide customer base make it an excellent fit with our company, and will allow us to expand our offering to better serve our customers.”

By Light is a portfolio company of Sagewind Capital. In 2018, By Light acquired Axom Technologies.

The McLean Group served as Phacil’s financial adviser on the deal.
