SaaS is revolutionizing B2B through its ability to develop innovative solutions independently of background. However, most SaaS companies fail within 12 years due to applying the wrong go-to-market model without understanding unit economics or building repeatable processes. To succeed, companies must use data to select the optimal go-to-market fit based on deal size, implement it through a proven process, and continuously improve operations based on performance metrics. This approach creates an efficient closed-loop system where customers fuel further growth.
