Meet the Founder
Sebastian Fidilio Jr.
Bridging the gap between accounting and business strategy.
I started sebCFO with a simple premise: small businesses deserve the same level of financial clarity and strategic insight as the world's largest corporations.
With experience spanning PwC and Deutsche Bank, I learned firsthand what actually drives value inside world-class organizations. I founded sebCFO to bring that same discipline, rigor, and strategic thinking to small businesses—where it's often missing and where it can make the greatest impact.
My approach is hands-on and direct. I don't just send you a P&L once a month; I help you understand what the numbers mean for your next hire, your next acquisition, or your exit strategy.
