We can't really answer this question for you. You might spend some time reading startup post mortems. They typically include some analysis. Then, in cases where they get real discussion here, read the discussion. Don't assume that the people who failed know all the reasons they failed.

Edison made thousands of light bulbs that didn't work before finally making one that did work. There are a great many ways to fail. Their failure does not necessarily indicate anything about the odds of your product. It depends on a great many factors. Given that you have not linked to your thing or theirs and haven't even told us generally what you are making, this question is just way too vague. And perhaps that is part of your problem generally.
