From Big4 Audit Partner to Fractional CFO ft. Samir Shandal

In this episode of From Wall Street to Main Street, we explore the nonlinear career journey of Samir Shandal, a CPA and former Big Four Partner who left partnership to build his own fractional CFO and finance advisory practice. We walk through his career, from studying biochemistry before switching to accounting, to starting in audit, moving into a corporate controller role at a software company, working in asset management, returning to the Big Four, making Partner, and ultimately leaving to pursue entrepreneurship. The episode breaks down what auditors actually do, why revenue recognition is such an important risk, how tech companies differ from traditional businesses, and how financial modeling, valuations, cash flow, gross margins, and financial statements are used to understand the health of a company. We also explore what changes when you move from audit into industry, how investors think about risk and returns, and what it really takes to make Partner at a Big Four firm. We then dive into the role of a CFO and fractional CFO, including the difference between an accountant, an auditor, and a CFO, how CFOs support CEOs in strategic decision-making, and why growing companies need strong financial infrastructure even before they can justify hiring a full-time CFO. Finally, we discuss how AI could reshape accounting and finance, whether the traditional Big Four pyramid model will survive automation, the impact of geopolitical and economic uncertainty on businesses, and Samir’s advice on entrepreneurship, career changes, building transferable skills, and navigating a nonlinear career. Chapters are included to help you navigate the discussion. Enjoy the episode 😉 👉 Don’t forget to like, comment, and subscribe to support the podcast!
