This is really nice and I like it a lot, disregarding of the "transparency" thing, I completely loathe when I have to "call to get a quote" for a SaaS. If you can quote a launch to orbit online [1], you can abso-fucking-lutely give me a concrete price for your relatively simple SPA when I'm browsing through it.
A suggestion, the price is unclear, is it per month? per year? one time? per the events described? Make that clear.
Congrats for shipping!
