The tax bill for ~$10m is <$90k. You don't need to take a loan from a sketchy loan shark - if you're remotely aware of this issue, you structure your investment agreements to account for lending you the money, and now you're taxed on commercial interest rates for it only, until there's a liquidity event.

This is a problem if you have no clue about the tax system and don't seek advice before your company has already reached a huge size.

I was 19 when I set up my first company in Norway, and had no prior exposure to business - I still knew the wealth tax was a thing to be aware of.
