Aaarghh. The AppSumo censorship has struck. So, I'm told that I've to rewrite my comment below, because AppSumo has "this review as the sentiment does not seem to match the rating of 5-taco." Thing is, this was a 5-star app for me, so why change the rating? Anyway, here we go: 2-stars, but original comment below.

Really sad to learn that Proposa is shutting down. This was an easy-to-use yet effective tool. Not sure what happened. The platform wasn't developed much after going live on AppSumo, so maybe this was just another LTD cash grab for them. Anyways, I enjoyed using Proposa. And it's not the couple of bucks I'm angry about... it's the time invested to learn the tool and the amount of proposals for which I now have to find a new home. If at all possible to export them. Still 5 Tacos as the tool was really good. I can't believe they shut down. Probably somebody bought them and it's the best way to get rid of all the LTDs sold on AppSumo doing it this way. Wouldn't be the first time.
