Phil Murphy

Phil Murphy is a Director of Business Development at WilliamsMarston, where he partners with private equity sponsors and management teams to modernize the Office of the CFO and drive measurable enterprise value through finance transformation and CPM solutions (i.e. OneStream).

Phil’s career spans public accounting, private equity investing, international M&A advisory, and portfolio operations—providing him with a well-rounded investor and operator perspective. He began his career at EY in Houston within the Assurance practice, serving public and private energy companies and developing a strong technical foundation in financial reporting and controls.

He then joined Main Street Capital’s lower middle market investment team, where he focused on buy-side investments and portfolio company value-creation initiatives. In that role, Phil worked closely with executive teams to enhance financial visibility, improve operational reporting, and support growth and margin expansion strategies across the portfolio.

Following his time in private equity, Phil moved abroad (Amsterdam) to focus on international M&A consulting, buy-side & sell-side due diligence and deal finance advisory – supporting cross-border transactions and corporate strategy initiatives for global clients.

Today, Phil leverages this combined experience of Big Four accounting rigor, private equity investing discipline, and international deal advisory insight to advise CFOs and sponsors on building scalable, data-driven finance organizations. 

Phil is a Certified Public Accountant in the State of Texas and holds a Master of Accountancy and Bachelor of Accountancy from the University of Mississippi. He is also a leader with ACG Houston's Young Professionals group.
