I too love Switzerland
It will be easier to attract foreign talents.
Talent is not a higher priority since I can hire local talent if needed. If need foreign talent can hire some remote employees.
Tax rates for individuals are crushing high in Germany,
Do you mean soloprenuership? I am interested in LLC / Private Ltd type ?
Power (if you're running server farms that's quite important) is much cheaper in Switzerland vs. Germany.
I want cloud facilities, server farms are an additional burden to maintain.
So in short: Switzerland costs a premium, but it's worth it, especially if you are planning long-term.
Can please explain this a bit more, I would like know the details from your perspective.
