When Jeff Kerr had his own firm representing plaintiffs in employment disputes, he couldn’t find law practice management software that did everything he wanted it to do—so he built his own. He’d work as a lawyer from 9 to 6 at Mays & Kerr, then go home and work on his software until midnight.

Kerr, 36, got so into the challenge of creating the ultimate law practice management software that he quit practicing law last May to start a company, CaseFleet, to make it. After eight months in beta mode, CaseFleet’s system is publicly launching next week.
