Guesstimate – A Spreadsheet for things that aren't certain
Cofounder Here: Happy to see this on hnews again.<p>Update: Matthew (the other cofounder) and I got Guesstimate to a stage we were happy with. After a good amount of work it seemed like several customers were pretty happy with it, but there weren&#x27;t many obvious ways of making a ton more money on it, and we ran out of many of the most requested&#x2F;obvious improvements. We&#x27;re keeping it running, but it&#x27;s not getting much more active development at this time.<p>Note that it&#x27;s all open source, so if you want to host it in-house you&#x27;re encouraged to do so. I&#x27;m also happy to answer questions about it or help with specific modeling concerns.<p>Right now I&#x27;m working at the Future of Humanity Insitute on some other tools I think will compliment Guesstimate well. There was a certain point where it seemed like many of the next main features would make more sense in separate apps. Hopefully, I&#x27;ll be able to announce one of these soon.
