The Real Economics of SaaS versus AI Companies
In episode #331, Ben breaks down the true financial and economic differences between a SaaS company and an AI company. Inspired by a tweet claiming that “SaaS metrics are broken” and that AI companies generate more absolute profit per customer, Ben puts the theory to the test using real financial modeling.
This episode walks through detailed revenue, gross margin, EBITDA, pricing power, TAM dynamics, and unit economics scenarios to determine whether AI companies actually outperform SaaS businesses.
