Not to deride the service, of course - it might be a fine product. It just seems like most of the other (modern) services available, if just a little bit more consolidated.
I just hope that
1.) it is easily extensible (as there is no way it will have an agent for all the software we run). Ideally the interface would be language agnostic (i.e. like nagios where the interface between the server and the checking code is just STDIN/STDOUT).
2.) The pricing model is reasonable once it goes out of production. We run a lot of single service VMs to isolate services. With management tools like Salt, it really makes it easy to mange, and a well tuned linux VM isn't that hungry on the RAM. It does mean that I can't afford to spend much on "per node" pricing. Especially the $10 per server per month that seems to be the norm.
3.) I hope there is a way to push stats into the dashboard from other processes.
Remember that it has to beat incumbent systems and open-source systems.
Per-host pricing schemes punish large installations and engineers who've created services that run on small, horizontally scaling instances.
In the end most of us end up with some wacky combination of different services.
