Matt Cosgriff, founder of The Advisor Library, is a senior operator and growth leader in the wealth management industry focused on how enduring advisory businesses are built. Over the course of his career, Matt has worked inside national advisory platforms and growth-oriented firms, leading teams across wealth management, advisor development, operations, and integration while partnering closely with founders, executives, and investors during periods of scale and transition.

Matt's work sits at the intersection of leadership, execution, and long-term value creation. A lifelong reader, he has long been interested in how the books and ideas leaders encounter shape their judgment over time — and how those ideas show up in real decisions around culture, incentives, and growth. The Advisor Library grew out of that curiosity, serving as a place to explore leadership and business-building insights from industry leaders through the books that influenced them most.
