$4K MRR and the only growth hack that actually worked: talking to users at the worst moment

We tried content. We tried cold outreach. We tried Product Hunt.
Nothing moved the needle as much as one stupid simple thing: asking users why they were leaving, right when they were leaving.
Not a survey email three days later. Not an NPS form buried in settings. A real conversation at the exact moment someone clicked cancel.
Here's what happened.
When we built Flidget.com, we knew churn was a problem for SaaS founders. But we didn't realise how bad it was until we started reading the actual responses coming through our own tool.
People weren't leaving because the product was bad. They left because of an unreported bug. A feature they couldn't find. A billing concern they never raised with anyone. Things that were 100% fixable — but nobody ever asked.
That insight became our entire marketing message.
We moved away from "churn reduction" and focused on the conversation you're not having with your users. That reframe resonated. Founders got it immediately because they'd all felt that pain — watching someone cancel and having no idea why.
We're at $4K MRR now. Not life-changing money, not yet. But the growth has been consistent and almost entirely through word of mouth from founders who tried it and couldn't unsee the problem.
The thing I'd tell any SaaS founder right now: your cancel button is the most honest feedback channel you have. Most of you are not using it effectively.
What's the most surprising reason a user ever gave you for churning?
