Good to know, I wasn't aware of them. At the end of the day the make or buy decision is influenced by the cost factor. In our case the development costed ca. 50k€ (obviously no SV salary), we had a user base of 10 data-scientists (incl. myself) and someone in house who knows the ins and outs of the system and can implement new stuff. I have to admit I was sharing my office with our DB architect, it would be hard to put a price tag on his support. I don't know how the pricing of the SaaS solutions compares to this.
