What is that bit about Bedrijfsaansprakelijkheidsverzekering at the end? I've never heard of business liability insurance before. Does Germany not have an equivalent of an LLC?
He doesn't want to create an LLC because he doesn't want anyone to question his motives.
Also this is the Netherlands not Germany :)
I don't know if it's standard for other business types as well, like in a BV (afaik that's what you call LLC). If you're not the only shareholder, it might help prevent legal issues when you make some mistake and it just gets paid from insurance. That's the purpose of it in a stichting anyway (negligence claims; getting into debts where you could allegedly have foreseen that the foundation can't afford it)
