I'm still unclear of the benefits. Could anyone shed some light: What can we do with it that we can't do now? Let's say that I'm a solo entrepreneur or small SaaS owner from a developing country (e.g from Asia, Africa or LatAm) -- basically, typical HNer who's not from Europe/US.
It is basically a way to make it easier for entrepreneurs to do business in the Eurozone and take advantage of Estonia's generous corporate tax structure. It's mostly a legal / financial device, you can't use it for travel or citizenship purposes.
For example, I run a small B2B company in the UK - would there be any benefits to incorporating in Estonia?
