Ask HN: We Cannot Seem to Be Able to Release

I've been working in a startup for the past 2 years working on a SaaS product.

I would say we have reached a good milestone in our product. however the project consists of multiple parts that each seems to be "could be enhanced" all the time, we haven't reached 99% of our target MVP, but... I mean sure, what newly released product is expected to have a complete set of features, or isn't expected to have some sort of faults?

so, the question really is, what do you suggest could be done to stop this eternal refactoring / enhancing problem?
