I worked at a SaaS startup, where after 5 years, the monthly earnings would barely pay for the AWS bill and 1 mid level engineer. Gross profit was single digit percentage, based on the official COGS. COGS was likely low, since it expected to make the bad numbers look better. Most of the company got laid off. Even then, like 150% to 200% of revenue was going to payroll.
