Greg Birman

Greg Birman is an author at NetWorth Explained. He has spent over a decade building, operating, and selling digital businesses, experience that forms the foundation of the SaaS reviews and financial analysis he publishes here. His approach to reviewing tools starts with signing up with a real account, running live campaigns or workflows, and living with the software long enough to find where it actually breaks down. He combines that first-hand operating experience with rigorous ROI analysis so readers can understand what a tool does and whether paying for it makes financial sense.

The net worth and personal finance content on this site draws on publicly available, named data sources, primarily the Federal Reserve's Survey of Consumer Finances, BLS occupational wage data, and published compensation research. Every assumption is made explicit so readers can verify the math. His editorial standard: cite the source, show the work, and label opinion as opinion. Content on this site is for informational and educational purposes only and does not constitute financial advice.
