About this episode

Benjamin Gruenstein discusses his transition from Cravath to founding his own boutique law firm and shares insights on recent legal developments and the impact of AI on the legal profession.

Earlier this year, Benjamin Gruenstein left Cravath Swaine & Moore, his professional home for almost two decades, and founded his own boutique, Gruenstein Law. Ben and I first met around the time that he launched his firm, after we were introduced by a mutual friend (but not his brother, former Wachtell Lipton partner David Gruenstein , with whom I used to work). I greatly enjoyed my conversation with Ben and thought that I’d love to have him on the podcast at some point. And now, the time has come. In our conversation, Ben discussed three topics in the news: (1) his departure from Cravath, which has seen higher-than-usual partner turnover this year, and why he wanted to launch his own firm; (2) Fernandez v. United States , an interesting and important case that was recently decided by the U.S. Supreme Court, which Ben argued before the justices; and (3) how AI is transforming the practice of law—and the role it played in Ben’s decision to leave Biglaw. Thanks to Ben for his insights—in our interview and more generally—and good luck to him and his colleagues at Gruenstein Law.
