I was in a similar situation a few years ago. The problem is that it takes some time to get to product-market fit. In our case, it took about 1 1/2 years to finally create the right app that people really wanted.
We had good feedback with early prototypes. But, you never have the full answer until the real app is in someone’s hands. So, we burned through 1.5 years of our Seed fund, were able to get the right app finally in people’s hands, but didn’t have enough runway left to market the app enough to grow fast enough to survive.
I wish instead that we’d been able to bootstrap the company long enough to get to a real product-market fit, and then we could have raised a round to double down on growing our customer base as quickly as possible.
If you already have fit and paying customers, then maybe you could raise money to accelerate things. But, I don’t know where you are right now with your product.
