40. Sotera Defense Solutions

Defense contractor Sotera this year bought Chantilly-based Potomac Fusion, a data fusion and analytics company that works for the Pentagon and the intelligence community. It particularly develops mission systems in a cloud computing environment. The company also made changes at the top, hiring Jennifer Felix, previously of Deltek and Vangent, as chief financial officer and Laurie Villano of Booz Allen Hamilton as senior vice president of Sotera’s cyber systems and solutions business near Fort Meade.


In Greek mythology, Soter was the spirit of safety, preservation and deliverance from harm.
