About Us – Sin City CFO
Your Partner in Profit
Sin City CFO was built on the belief that small business owners deserve more than just bookkeeping and a tax bill at the end of the year. You deserve proactive advice, strategic planning, and a partner who helps you make smarter money decisions every step of the way.
Our Beginnings
In 2019, after nearly a decade in finance, founder Patrick Darby launched Sin City CFO with a simple mission: help online business owners finally get clear about their numbers and pay less in taxes.
Frustrated by traditional CPAs and financial advisors who couldn’t answer the questions that really mattered to growing entrepreneurs, Darby decided to create a service designed specifically for online fitness coaches, content creators, and service-based businesses.
