Congrats on launching. Very interesting. Does it support localization / customizing the look&feel? I couldn't work out if it's something that runs directly on our site, or we need to redirect to yours... I think some more documentation/info before you sign up for a trial can help give better confidence about what's involved and how it actually works (although the homepage is awesome and explains the value proposition super well).
Like others, I'm a bit on the fence about the ethical aspects of it. Yes, there's a lot to say about giving real value, listening to customers, but it does start going down the path towards darker patterns like Amazon Prime (there's a looong way to go down that path, but still feels like a step there). I'm not trying to criticize, but just voice my personal feeling around adding friction to cancellation.
