A little more info would be helpfull. I would provide the following info in your post to help filter people to the right match:
Are you guys funded?
If not are you guys looking for someone with funding?
If so what is your burn rate until implosion? (this lets people know worst case scenario)
When do your expect to hit profitable.
Is salary involved or is this a, when we get funded you get paid gig?
Where are you guys located?
Are you cool with someone remote for now?
What is your current technical platform?
Who built it, an internal person or outsourced entity?
Who is already involved, what do they do, what do they bring to the table?
As well just food for thought, but there are quite a few on this board and elsewhere that hate rock star and ninja as a description. It has become manager speak for "we are trying to be cool but we are out of touch with the tech type". Not saying you are, but those descriptions set off flags for some.
