One of the projects is from Fornax, called PixelDrain (
http://pixeldra.in/) Right now it is not using Sia backend (but his own server instead), but he is working to implement Sia, accepting BTC for larger files, and implementing in the future video streaming. I can't disclose about the second project, sorry, it was a personal communication.
Do you mind telling us how many developers are currently working on Sia as a full-time job?
Nebulous Labs is formed by 4 full-time developers
