A more focused data warehouse product that is priced on a better model and is more scalable and efficient and cheaper than any of the existing options. $500M means they'll be around longer than most of the startup customers that try them.

Anyway, at this point I'm just repeating myself so I suggest you actually try them if you care for a better model. It works for us at 600B rows of data that was too expensive with BigQuery and too slow and complicated with Redshift/Spectrum.
