I'm afraid that unless he brings something substantially unique to the table, his chances are just very very slight. There are a few people who can raise money on their name and reputation alone. See: Steve Jobs. If he were one of these people, however, he wouldn't be applying to incubators, he'd be turning money away at the door. Instead, he NEEDS something to show off. No matter how awesome he is, he NEEDS a product. Slides won't cut it. Again, let's look at Steve Jobs. Arguably the best "idea man" or "business guy" in the history of tech. Until he and Woz put together their Apple I, and started selling it in shops (read: traction), even he had zippo. In short: Get a demo, get users. Ideally, get a co-founder. Then, maybe, you can get funding, if you still need it.
