Your service is useful, but not all mobile backend requirements can be solved with cloud storage of key/value pairs.

This statement is completely correct, which is why Parse is adding so many features besides just key/value storage. You can already store relational data, do geo-searches, user authentication, file storage, push notifications, and lots of other stuff.

Our goal is to let you write any application without running your own server. If you think you can't build your application on Parse, drop us a line at feedback@parse.com and we will be glad to either figure out how it can be done, or put it on our todo list.
Not trying to be overly critical here, what you've built is very enabling for a lot of app creators. But it seems to me that any really successful client of yours will eventually outgrow your feature set and need to migrate to a custom solution.
At that point I don't know how you hold on to those customers without needing to build something like a Heroku.
This is a good point. One convenient feature of the Parse platform is that it's located on EC2, so developers can run their own servers on Heroku or just EC2 itself with <2ms latency to Parse if they need to run any generic code. So we can let Heroku build Heroku, and just make Parse work really well in conjunction.
I think right now we have reasonable solutions for this. We would like the solutions to be not just reasonable, but amazing. So there are a lot of other ideas we have to make this sort of development easier. We're working on it.
If I was looking to make a minimum viable product to attract investors then I'd probably use a service like Parse to speed up development.
Once you're swimming in investor dollars you can worry about hiring people to build your own custom back end that has all the bells and whistles you want.
