They each put a quarter share of $1,000, per the article:

The four cofounders each own 25% of the company, and at launch each put in $1,000 to cover initial costs.

The blowback I’m referring to wouldn’t be kinetic, it’d the loss of the monetary hegemony provided by American lead banking system and the USD being used as the global reserve currency.

This is one of those actions that is completely understandable and an unambiguously moral decision, but the blowback has the potential to upened the entire post-WW2 American centric global financial order. Maybe for the better, maybe for the worse, I don’t know, but it’ll probably depend alot on what your vantage point is.
