I'm using churnguard on my own business and implemented it in a friend's business, and honestly the performance is here : i've been reducing my churn rate from 13% to 3%, saving around 13$ ARR. UI UX is pleasant, the integrations were matching mine, and the pricing is fair for my business with around 230 customers. The onboarding was a little bit "tech" but I went through in around 10min.
