If you dont disclose any details I have to assume that "the founder" and "private investors" indeed dont finance anything and those 40% are a management fee. So its still only 45% (0.75*0.6)
To rephrase this, you want to keep all investors who finance 100% in the dark.
All companies are like this, the founders get a chunk of the stock in the company. Friedcat owns 50% of ASICMiner and Mark Zuckerburg owns 50% of facebook.
