The Rule of 40 originated within the venture capital and private equity spheres, especially from the tech industry, as a way to quickly gauge the financial health of SaaS (Software as a Service) companies. In these sectors, relentless growth frequently required heavy investments, which could sometimes come at the expense of profitability. Investors recognized the need for a balanced approach: companies should grow quickly enough to warrant a premium valuation, but also show they could control costs and eventually generate profits.  By integrating this principle, your business can adeptly balance increasing revenue while maintaining profitablity.
