Also adding this:

https://eazybi.com/

which is a SaaS run (I think) by rsim.

Yes, I can confirm that https://eazybi.com is built and run by me.

The goals of eazyBI are as described in the question - simple way to upload your data or import from other applications and easy to use OLAP reports, charts and dashboards. And it is built using Ruby on Rails and Backbone.js as well :) In the backend it is using Pentaho Mondrian OLAP engine which is embedded in JRuby open-source library https://github.com/rsim/mondrian-olap

eazyBI looks very interesting, but your site and sales pitch seem pretty unpolished. How big is your team and where are you situated?

Currently it is primarily just me and I am from Latvia (Eastern Europe). And trying to improve site and sales pitch as well, I appreciate any feedback :)
