Sounds like you definitely are bringing something to the table. Emphasize your demo and domain knowledge (from other comments:
"Once our demo is working, we will decide together how to go forward, but I probably will be focused on design and medical aspects"
"A large aspect of our company will include components like creating a medical protocol, clinical trials and medical demographics"
Also, as CEO you probably have the final say on decisions, so make sure you make smart decisions. In order to make smart decisions, you need to know the costs and consequences of technical decisions, and you need the hacker to give you these.
You need to have enough technical knowledge to assess what you're given. For instance, how much do you know about the iPhone, the new SDK, the background processing limitation, and the possibility of Andriod looming in the distance? If you can't have a discussion about that, you're going to have a hard time hiring a hacker that can do that work. Rule of thumb: you can't hire someone if you can't have a long conversation about what you want them to do.
