  • Age: 38
  • Title: Founder and CEO
  • Company: Lanmark Technology

This Naval Academy grad has grown the threat analytics firm she founded in 2003—it does things like predict the location of IEDs—into a fast-growing government contractor with revenue of close to $40 million. Hay spotted opportunity: As a woman, a minority (her mother is from Vietnam), and a service-disabled veteran (her hearing was damaged while in the Navy), she knew she'd have an edge in the contracting process—and that the government has to expedite pay to small businesses. Hay has political ambitions: Her fundraisers and events are celebrity- and politico-studded.
