Thomas of ZenMiner has been fairly public and was open with me when I interviewed him.
I'm not aware of too many privately held companies that disclose all of their employees or the internal working of their company, such as what other avenues they might be pursuing. In that respect, I'm not sure it's reasonable to demand that information.
two things..first I didn't "demand" it...I said, I would like to see this....second, I suggested listing their "principals"...i.e. owner, vice president...this is quite common, even for private companies.
