I also want to second the suggestion to make this FOSS. I know you fear for the economic repercussions, but unless your product is unique and super game-changing (which IMHO it isn't), people will mostly pay for the service they get on top of the product. This can still be a differentiator, even when the software itself is also available as FOSS.
This product could have easily been FOSS with it's pricing model based exclusively on support/hosting.
If you want early-adopters - be hacker-friendly, not money/data-hungry.
Would have been an instant install otherwise.
I've used DatoCMS and I actually really liked it. However the pricing model is quite steep for the service it provides. I feel that if open sourcing isn't in the horizon, at least consider expanding what the Free and Basic models provide.
