You know .. this is a quirky but interesting idea. PG started YC because of his experiences/challenges as a tech founder. Maybe someone can address this niche. Obviously, the funding terms would be different. There are legal issues having to do with existing employer contracts .. this could be a rathole. I am not sure doing a startup as a side project is at all useful .. but I might be wrong.

One comment I have to make .. risk is the name of the start up game. Maybe business in general. You cannot completely de-risk it and still call it a business.
