I have a demo because my startup is allready in operation for months. But what is a demo? The technology I demo is very special, but will Ycombinator spot that in a minute? I doubt it, it needs a person presenting the demo. If it is very obvious how good the technology is (it is!), we would not need to apply anymore.
