I've built GrantTree's financial modelling (real time, to the penny) using a Ruby/Rails back end and FreeAgent for the transaction management.
No Excel in sight. The only thing we use Excel for is client calculations and holiday tracking.
- daemon13 13y agoWell, it is probably possible to do financial modelling in Erlang (fault tolerance, etc) or Go (good concurrency support). But why would you need this? You can do financial model in 1 hour using Excel...
- swombat 13y agoBecause it is far more clever than anything I could do in Excel. And it doesn't require me to duplicate information all over the place. I'd rather have just one master source of data that I do all the calculations on.
- PeterisP 13y agoIf you're doing deep analysis on large historical data, then it's in essence a MIS system, and most businesses do (and should do) that outside of Excel. But what the article is about, in a growing startup or a changing company (say, completely new product line) the 'one master source of data' is not in a database but the assumptions in your head; and any clever model based on your historical data will be either impossible or far more wrong than a simple order-of-magnitude calculation done on a paper napkin. And, well, Excel is more convenient than the napkin.
