I used Sage in the math department at Bard College with Prof. Greg Landweber. Honestly it felt a little half baked but when it was good, it was amazing (and my impression was that it was completely free, no option to pay). My armchair critique: - The concept/vision are great and you could be a serious competitor to Mathematica if you got a product person on board. It has all the power of mathematica, a more popular programming language (python), and a good user-acquisition strategy (professors are already using it for college courses... you just need to get the students to take it with them when they leave the course). - You need a product person / designer because there are serious UX gaps and the feature-set feels really scattered. For instance, the fact that I had no idea you could pay is a big red flag. - Figure out what your goal is. Are you making Mathematica or Linux? My guess is it's more towards the former and you should apply to YC. Edit: Thanks for making Sage, BTW!
