Fivetran looks very cool, although I'm only worried that it's web based tool.

Advanced Excel / SPPS/ Matlab is used by professionals, who want very fast and responsive, something that is hard to replicate in web based app.

I wish them good luck though!

1010data provides a web product for performing transformation on large sets of data and it's quite nice. We used it when we used to do analysis of mortgage pools etc.
