Got rejected by 3 VCs feeling hopeless. I will not promote

So I came up with the idea that would solve the operation problems in organising an event for exam if it's a wedding or effects of big formal conference. So it would simplify networking the app that we built was similar to swapcord and Cvent. So basically what we do is we digitalize the map of the event. We automize the schedule we have AI features and which attendance can ask a way to go what to happen when active voice system. We also have active alert and a share photo gallery. And on top of this we are also providing a feature in which they do not even have to install the app. The app will work like a PWA app(web app). The review I got from investors were that you are trying to solve a lot of problem at once and try to solve less problems. And one of the investors side like a Tam is very small and they don't think we can scale. For the next investor meeting we increased and generalized our TAM and the investors said that we feel that you are deceiving us. But also with this we have been able to get some pre-speed funding (very less nearly 1000-2000 dollars) because of our past social work. So I am in a dilemma. I do not know whether the problem we are solving. Do people really care about it or is it really worth putting in the food? Because we have invested around 6 months in developing the minimum working product and we are planning to hire interns and further try to grow our Start Up. I don't know if i can share the link to our website here but i would drop it in the comments. If possible can someone who has been in our shoes help us find the correct direction?
