Who is this course not for?

Drop Shippers/importers

-This course focuses on creating new products for new market opportunities.

Software products

-Software products have their own development pipelines and best practices. Some hardgoods products have software components, we will talk briefly about these but it will not be a focus

LARGE projects

-Many Inventors have project ambitions that require MANY key relationships to be established with large existing corporations. This course can help you create the necessary products but communicating with those big companies is hard.
