We've been working on ChurnKit for the last few months as an internal tool, to find out who has removed our javascript code from their website - to collect their feedback.
We invest in acquiring new users, we try to make them signup and try our product by adding a small JS code to their website. But then, 10 days later we found out our code is no longer installed on their website.
Such a waste!
With this, we managed to recover several uninstalls + collect valuable feedback since we started using it internally.
If your product or service involves adding a small snippet to a website to make it work, I'd love to get your feedback on this.
