We looked at ServiceNow's ITFM offering back in 2015, when we run the RFP that ended up us signing up with Apptio's CT module.
I went to their annual conference, did some training and talked a lot with the ITFM product manager. He did know his financial management, for sure.
What I remember from the product is that it was very customizable - like everything else in ServiceNow. You could do just about everything and the system tried to help you map the data, in a remotely similar fashion to the new A.I. features in CT. It did have some machine learning capabilities and tried to predict what to do with new, unmapped data.
Our Controlling team found non-negotiable some features that ServiceNow's product was missing, but CT had. ServiceNow got desperate to get the deal and threw in everything for a ridiculously low price. Still, we decided for CT based on the features.
After that, something happened in ServiceNow and the PM left (or was discharged).
At some point I thought they had some integration with CT. I remember seeing something like that at a Gartner summit, or some such conference, but it was at least 2 years ago, possibly more.
