The race to legal tech is certainly picking up speed. News broke earlier this week that the accounting firm of EY had inked a deal to begin using AI contract review platform Luminance inside of its global legal network, making it the third of the Big 4 accounting firms to adopt the legal machine learning platform.

The move comes just a few months after EY acquired the alternative legal services provider Riverview Law, signaling a deeper commitment to the managed legal services track. EY isn’t the only Big 4 member building ties to the legal tech industry either. Earlier this month, an alliance between Deloitte and e-discovery software provider Relativity spawned a workflow platform geared toward managing Freedom of Information Act requests.
