I had a couple of clients that were comparing OneStream with Anaplan. One of them chose OneStream over Anaplan, and the other is still deciding. I don't have experience with OneStream, but a close friend of mine is a consultant there. He says that the features are similar.  I connect clients to him if they want to hear more about OneStream. 

We evaluated PCM.

Before choosing this product, we also evaluated TM1, along with SAP Business Planning and Consolidation.

I have evaluated other solutions and Anaplan is better than other competitors out there.

I haven't done this, as it was already selected by my organization. However, I did some market research to see how other options are flourishing, and found Anaplan to be a worthwhile option.

We also looked at Salesforce (native forecasting solution), Adaptive Insights and an IBM solution.

We had evaluated Tableau and QlikView. Even though a lot of the other tools do a good job, only Anaplan allows flexibility and customizability to design solutions and do real-time “what-if” analysis.
