How do you tell product market fit? we have about ~1K paid users, people constantly send positive praises, but also many people churned away.

I doubt if "bootstrap" is the right way for this type of product/market.

The famous PMF survey (how do you feel if you can no longer use this), %50.8 responds with "very disappointed". And I deeply know this product is pretty unique offering in "finance tracking" market.

But the MRR stays in this level for 6 months now. I feel I do not have ideas to break it through.

There are some big parts identified for this case, and because it is dependency of 3rd party service, we can not do much about it.

But more importantly, I think it is the product itself, the market is probably does not appreciate that much of "customization / personalization" as I thought, in other words, we are probably haven't figured out the best path to get the ideal users yet.

In the other side, free users do not have this issue. We do have free tier which counts for 1/3 of all active users.
