Hi anish_t,

About six months ago I tested Kinvey (a BaaS) for an application that makes heavy use of data. Basically you upload your data (say, from CSV) and then you access it via API calls.

It looks like you can download your data at any time, say if you need to switch providers. I don't have any experience of other providers, but with Kinvey it doesn't look like there is a risk of vendor lock-in. It's data on the wire via AJAX requests. If things turn to be expensive when you grow up, you move the data to your own backend.

That said, I must add that I never ended up using them. The reason - I just needed something with serious geospatial capabilities. I mean PostgreSQL + PostGIS kind of thing.

There is also the DIY route, which is not necessarily the best, since it will prolong the time until you release a MVP. But, if you have the manpower to work on it, maybe Drupal is a good alternative for you. It can be set up as a backend, it is secure, and it's free. I think you can even set it up as a SPARQL endpoint.

Good luck with your startup! I don't wish you to reach millions of users, but instead to make millions of dollars :)
