What was the specific need for privacy again?
One the one hand you'll be performing a very public 'spectacle' as you say on your website. On the other hand you want to keep your identity private. What if the media wants to talk to someone. You're going to need a lot of media attention so that initial investors get a return.
But it doesn't sound like your team is willing to even put a name or face on this project.
I hope you understand why everyone is so skeptical about this. It would be very easy to keep the IPO money and not deliver.
