One mystery we did not resolve (pun intended) was why it did not find its audience. Was it too early? Was data science not established enough as a field? Was it because it was not Excel (i.e. the dominant tool)?
I think it was a combination of those, plus terrible market timing -- we released it, thinking we could sell to finance types, in 2008. In our sales pipeline spreadsheet, the "notes" column started saying things like "customer has gone bankrupt".
