There are bootcamps for people to become developers in 3-6 months of time but are there bootcamps that help you become a founder?

I feel there is a mental resistance in me (and may be others) to feel ready before they can start a company. There are a lot of skills involved in starting a company. I am looking for something like a Toastmaster but for Startups where you can learn skills and have a group that support you in starting a startup or small business.
