You would really suggest that this training offers nothing of value? Pretty much. Early stage startups don't need to know anything about finance, business law, and management. All they need to know about IP I can tell them in 5 minutes. As for marketing, it depends what the schools teach, but startup marketing is so unusual and varies so much depending on the product that I would be very surprised if a B school class had anything useful to say about it.
