Kim Posnett

Kim Posnett's career has long been on the rise at storied Goldman Sachs. So it was fitting that to mark her two decades at the firm, she ascended to even more rarefied territory: co-head of investment banking.

But before that January 2025 crowning, it was her previous role as head of global technology, media & telecommunications group that groomed her for the even bigger chair. That put her at the center of major events like Twitter's $44 billion sale to Elon Musk, and Silver Lake's $25 billion taking-private of Endeavor. High-stakes deals like that helped cement the firm's status as the #1 advisory in worldwide, announced and completed M&A for the year. (Posnett is ranked on her prior role of Global Head of the Technology, Media and Telecommunications Group, per American Banker's methodology requiring that a woman be in her role for at least one full year.)
