We looked at Amazon SageMaker on AWS. 

This product still was open source at that point, then we did get proprietary support after that. The other products were not open source, and we couldn't really try them out beforehand to see if we liked them or not.

H2O.ai is a great product for data scientists in general. It has a lot of options and is really flexible. Also, the pricing was good.

It was already selected. I don't know what process the company went through.

We have experience with pretty much everything available; hence, the switch was an informed decision and natural.
