Origins don’t matter, it’s a vanity metric. You can’t control where you originate from so that’s not actionable data. What matters more is seeing where companies are ultimately establishing themselves.

That's just a measure of where is most friendly to founding a company. Either that or there's something in the water in Delaware...

That's a bit inaccurate too, because your r&d and sales could be in two different places.

Raising money in US, selling in Western Europe or US and having R&D in Eastern Europe is a thing

Yeah but if you only sample YC, then ofc everybody ends up in SF, which is also a vanity metric because all of them are actually located in Delaware
