I can see a parallel with the "why Europe doesn't have as many big tech companies as the US" discussions. Now change the question to "How many companies does the East Coast have in comparison with the West Coast." Or even SV. (Even if most companies are actually established in Delaware)

Ease of finance and management vision (which kinda related to the first point) seems to be the main drivers.

The caveat I'd make about that comparison is that the question a lot of people end up asking is "How many SV flavor of tech companies are on the East Coast vs. SV?" Ignoring, for example, biotech, defense contractors, finance, etc. The comparison isn't invalid but it's certainly biased towards tech=web-scale.

If you Wikipedia List of largest companies by revenue, most seem to be headquartered in the East Coast and Midwest
