List of User/Supporters

It may be useful to have a listing of companies and projects using ShareDB, in the README somewhere.

I know there are many people using ShareDB in production apps today, it's just not clear to newcomers.

We can improve the initial impression of ShareDB by listing users and supporters.

Here are a few that come to mind:

• Lever - Founded ShareDB, using in production.
• Retrium - Not 100% sure, but I think they are using ShareDB in production based on vague memories of discussion threads.
• Decision Mapper - I know they used to use Derby heavily, not sure if they are still using ShareDB. @zag2art @cray0000 Any comments?
• Datavis.tech (my company, a collaborative data visualization platform)
• FROG Analytics

Any others? Who is out there using ShareDB in your product/project and interested in its long-term health as an OSS project? Please post here and reveal yourselves!
