For what it's worth, I need your product and know other people that do too. I would pay for it, providing I didn't have to pay much.<p>Increasingly, we have big data sets, and want to work with them collaboratively. Because they are so big, the problem of how to proccess the data is added to the old problem of what to do with it. I think that centralizing the 'how' would be a great selling point too.<p>Maybe I explained that badly - in Amazon AWS are a bunch of datasets.If I want to play with them, I have to create an AWS instance, with the right tools, go find the data, and spend time figuring out how to read it. If your online Matlab also helped me handle data, then for opensource data someone would only need to solve that problem once (ingest), and for closed source data, at least I'd have a common platform with my team.<p>Anyway, my imagination of what your product could be, and all the problems it could solve, has me excited. I encourage you not to give up or lose faith in the concept.<p>This is entirely putting aside that yes, Matlab is expensive, and for occasional / home users, it would be nice to have something subscription based rather than couching up for a perpetual license.
