Pillsbury hires Oz Benamram as first Chief AI Officer, builds four-director AI leadership team
Pillsbury Winthrop Shaw Pittman
Pillsbury Winthrop Shaw Pittman hired law firm executive Oz Benamram as its first Chief AI Officer, tasked with hiring a team to expand the firm's AI use. Benamram helped shape four new director-level roles reporting to him: knowledge management and innovation; data science and AI engineering; practice applications; and AI transformation. Unlike Kirkland & Ellis's $500M proprietary AI platform strategy, Pillsbury's chair said the firm does not plan a capital-intensive build-out, instead treating AI investment as inseparable from broader firm strategy. The firm currently uses ChatGPT, Harvey, CoCounsel, Microsoft Copilot, Definely, and ClearBrief.
