I agree, even if they decide to persist with this, they need to grow into a more robust business (ex. focusing on the abandoned cart followup niche) than just being an API that can get shut down overnight.
And yeah it's definitely late, but I'll just take what you said as a push to actually bang it out today and try to fight my tendency to write and say way too much on those kind of things, haha. It's only half tech related anyway, similar problem space as Firstbase.
