A legal technology firm filed a lawsuit in federal court Monday accusing a former employee of stealing two Big Law clients when he defected to a rival technology vendor.

Washington, D.C.-based Legal Technology Group Inc., which does business as eSentio Technologies, says Rajiv Mukerji was managing the accounts of Akin Gump Strauss Hauer & Feld and King & Spalding before he left to join HBR Consulting. Shortly after, both law firms contracted with HBR for their migration to cloud-based document management, according to eSentio’s suit, which seeks $10 million in damages.
