Many internships will ask you to do menial things, and this one does not.  Many internships will also look at you as “free labor” and not invest much into you, whereas this one looks at you as an investment in the next generation of innovators and world changers.
Beyond all that, the primary difference is that internships are largely not geared toward entrepreneurship, and this one IS.  As the owner of three companies, there is a great deal to learn about starting, growing, expanding, and exiting business.  The things that are not taught in school will be discussed often, such as:  wealth accumulation, legacy planning, dream building, money management, sales, business modeling as an entrepreneur, mental health, personal development and so much more.
This is a wild and exciting ride for the person who is eager and itching to build their dream life with support from an expert.
