Why domain operator
Sam Ross's primary archetype is 'Domain operator' because he founded Numeral based on his personal experience with the complexities of sales tax, indicating deep familiarity with the problem space. His frequent detailed posts about tax regulations and their nuances further support this. He also exhibits traits of a 'Technical builder' by focusing on AI and automation to solve these problems, and a 'Community builder' through his engagement on social media and support for other founders.
