Hey guys, this is really baffling me and I honestly don't know what to do. We are building a SaaS tool that lets online marketplace seller calculate their income seamlessly and quickly. This far, we have 4 users and we contacted each and every one of them, asking for their experience and feedback using the web app, and whether it's useful for them (whether we have product/market fit). None of them replied. Their response is one of the most important thing we could have right now and none of them responded.
What would you guys do if you were in my shoes?
