How SaaS startup guys get first 100 customers first, make fkn $500k ARR fast?

A founder of an AI security audit app is struggling to gain customers while seeing others claim $500k+ ARR rapidly, questioning how they achieve this without paid advertising. Responses suggest the gap comes down to methodical go-to-market execution—particularly manual outreach on LinkedIn and understanding ideal customer profiles—while others caution that some high-revenue claims may be inflated through annualization or misleading metrics, and advise focusing on genuine product-market fit rather than chasing vanity metrics.
