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.
