This company is clearly no longer operational, but as a user, I couldn't tell untl I had spent hours training a bot with my material. I even saw that there is still a link for people to set up as an affiliate to get commission from selling re:tune! This is unethical and a complete waste of time and money. I don't know how or where they got so many 5 star reviews from because even if they were that good in the past, a reputable company would put a popup on the website advising customers that they are no longer trading. Unfortuntely, I'm finding this with an increasing number of purchases now and it is making me think twice before buying, although I commend AppSumo for their customer protection policy - but there's a limit to how much AppSumo can support these businesses.
