Do the US companies benefit from hiring people outside the US? Or is the international hiring fake?

Yesterday, I came across a post by John Rush on Twitter.

The idea was simple:

"American companies could significantly reduce labour costs by hiring remote workers from Europe or Asia."

And honestly, that seems realistic, at least for roles like software development, content creation, or social media management stuff.

BUT...

For positions like sales or business development (especially where strong relationships with key partners are essential, e.g. Business development, Sales), it's much harder to outsource.

These roles often require a physical presence or at least a deep understanding of the local market. (When you want to sell to Americans, you should close deals and meet customers in the US.) So naturally, it depends on the role and industry.

Among all the U.S.-based startups I’ve come across, only a few hire outside the U.S. Most are strictly U.S. remote, no visa sponsorship.

How do American startups approach international hiring in reality?

I would like to get a statement from these startups what is their policy on this, and if they do not hire in Europe, what are the most common reasons?
