Remember the fundraising total didn't include private investors who helped before crowdfunding started. They already had some money in the bank, crowdfunding was simply meant to prove there was an appetite for the game. We've no idea if those investors are still involved and if the original ones were paid back, I doubt it.
Either way they will likely have raise another couple of million this weekend alone.
There are no private investors.
The money for the start up was from Chris and Ortwin.
