They've raised money from investors and from companies like Intex who they have created custom phones for... but that will be increasingly difficult to do - they have a vicious cycle of:
hard to get a device -> few users -> few apps -> low demand for devices.

Jolla now is a lot smaller than it was when large numbers of employees were getting on stage at Slush. From here to a profitable, stable ecosystem is obvously a big leap but I hope they can sell lots of licenses for the Xperia X. I'll certainly be buying one.
