At Cloudron, our vision is to allow companies to host their own apps easily. We dogfood and don't use Google. We don't use analytics on our website (a conscious decision). Our emails are based on IMAP servers and we use thunderbird. We selfhost everything other than email (which is on gandi).
Cloudron and sandstorm are similar projects. I think the main difference is the user experience (also how we handle domains, how apps are packaged etc). You can see a demo of the cloudron here - https://my-demo.cloudron.me/ (username: cloudron password: cloudron). All apps use same credentials (because of single sign on)
We just entered private beta yesterday - https://cloudron.io/blog/2015-12-07-private-beta.html
