"But just because PG won't read your plan doesn't mean your startup shouldn't have/make a plan!" This is true not just for startups and its great advice for life in general. However, I believe YC would actively discourage founders from writing a traditional business plan. They would rather have their startups talk to users and building products. To put it another way, I think YC would say that you cannot possibly write a realistic business plan without a solid customer base and a good product. Anything else and you're just making things up. By the time you have customers and a good product, you don't need a business plan to raise funding. * This is what I've gathered from their startup school materials without having raised a dime from YC or talked to any of the partners, so take this with a big dash of salt.
