Price transparency is not optional for SAAS products. Seems to be a well kept secret on their website. Instant turn off for me. It means there are hidden costs, special deals at the discretion of some sales person, and other sales BS you have to deal with. I see this as an anti pattern for a SAAS service. We pay for lots of SAAS stuff at the company I run; we don't talk to sales people for any of that stuff ever. We engage with their support when stuff is broken. But not sales.

Redis is a great product but I fail to see the valuation that comes with a 60M investment (a billion+?). Yes, the cloud offered variety could potentially be interesting but competing products are available and this seems to be a commodity product running on commodity hardware. AWS already offers it so do others, I believe.
