On October 2013, Ronald Greenberg, a litigation partner at Kramer Levin Naftalis & Frankel, agreed to advise Elizabeth Elting of translation software company TransPerfect Global Inc. in a dispute with her co-owner and co-CEO Philip Shawe over the management of the business.

As relations between the two business owners worsened, Greenberg became Elting’s sounding board, he recalls. Emails between lawyer and client flew back and forth seven days a week, with urgent messages sometimes popping in Greenberg’s inbox in the middle of the night. “I knew this was going to be a storm,” Greenberg says.
