Hi guys, I'm a founder at Domino Data Lab (one of the other companies mentioned in the article). I'm happy to answer questions anyone has. I can also corroborate the opinions in the thread here: many of our customers are in finance and insurance, and many of them don't want data leaving their networks at all (hence the need for an on-prem offering).

Is the on-prem offering a combination of "OSS private cloud" and a proprietary analytics / machine learning API?

[DominoDataLab]

We don't offer a proprietary ML library or API -- we run arbitrary user code, whatever languages and packages you want to use (Python, R, h2o, dato, compiled C++, etc.). The infrastructure piece is like a private cloud, yes.

I've always been confused as to what takes a long time to calculate in finance. What are the common difficult problems that aren't getting solved?
