Hi Ying, I enjoyed the venture pitch and how you incorporated the ‘testimonials’ into discussing the pain point. It’s definitely a problem I have felt many times. One of the issues I’ve ran into is creating appropriate keys and updating them. Our school has some great in house workbooks, but with frequent updates our keys are always out of date. Making good keys and uploading them has always been a chore and this presents a way to address that. That being said, this venture feels like it will really depend on word-of-mouth marketing. If it gains popularity with the right teachers it will sell very well, but competing against the big publishers I think will be a significant challenge!
