FEEDBACK : I really like the idea of the venture. I am sure there could be a lot of takers for this product, however it would depend on how it is priced. Being an ESL teacher myself, I agree that such a product would save a lot of time.. I think the pitch was done very professionally and included most of the checkpoints. As a suggestion, I would recommend adding a little music to the prezi. Also capturing a 50 % market share by 2015 -16 seems a little ambitious to me. Good Luck !
