Trying to build a company and I need to make sure if there exists an audience

This is exclusively for companies, colleges or hostels with multiple floors, where everyone is in a rush to get into an elevator. I realised this when we had a huge crowd standing in front of the elevator at my college. If only I knew where the elevator was at a particular time, it would be easier for me to plan accordingly on when to leave. Worse, sometimes, the lift is full and it would be easier if I knew that already instead of waiting in front of an elevator like an idiot. So I built an elevator tracking app to make the process systemised and make the lives of students and office employees easier. However, my college start-up incubator perfectly pointed out that the audience is pretty slim since there aren't many buildings with so many floors like our college in Chennai so it is, a very small audience. Therefore, I'm trying to gain data if people want this. If I have a strong number of people from different companies or colleges wanting it, I can make this idea work. So, please let me know if college students or employees want this or not.
