This is such a good idea and has a potential to become big if executed in the right way. In my opinion, the initial focus should be more on creating the buzz by targeting the coaching centers and schools or universities. It is important to understand that the end consumer is mostly the students and the money for an individual premium subscription, money should come from a parent. It's very hard to make a parent understand the utility value for this and so, a B2B model is the right way to start the journey. With the buzz created, more people who can shell money out of the pocket for a subscriptionmay join who are willing to interact with people having similar interests, probably in music or gaining/sharing information from their desirable hobbies. The potential is limitless but caution to be taken not to spread to thin trying to do all at once. It's important to gain the traction, get profitable soon, scale up to various geographies and then start new verticals. Kudos for bringing up a genuinely interesting & workable concept and ALL THE VERY BEST 👍🏼
