I think your problem is your potential market. How big of a market is there for Data Science?

The thing with codecademy is they could potentially attract hair dressers, janitors, etc. Your main target are people with degrees who have an interest in data mining.

You are either not describing what your product does correctly or you have a unrealistic view of your potential market.

Your team sounds great but I really can't see the demand for data science knowledge being that great.
