Ask HN: How do folks without 'seniority' in a domain launch, e.g., 'AI in SRE

I saw the name of this company in my feed and took it as a complete random example. Nothing particular about why this one. But I picked to highlight a trend I've been seeing lately.

The founders appear to be novice in terms of real world experience. And I did not spot any certification that could be valued for a SRE engineer, for example CKAD. Nor they seem to have worked in SRE domain for say minimum four to five years to display seniority and domain knowledge.

Yet, somehow, they have pitch and 'enough' experience to justify and showcase to the world a 'AI SRE for Incident Response'

Like, what am I missing here? This is like me with zero experience in dental practice to launch an AI firm in dental space to solve dentist's problem.
