Is Rethink DNS a VPN?
It's not a VPN (yet):
What Rethink DNS is not?
It isn't a VPN, at least not yet. Though, it is effective in circumventing internet censorship in most if not all countries. Rethink DNS uses VPN APIs to only route the DNS traffic and not the actual internet traffic.
Rethink DNS isn't a tracker. Rethink DNS logs DNS requests if a user opts-in. Rethink doesn't sell any user information or use it for anything else other than to provide analytics and reports to the user.
and
What else are you working on?
Apart from adding features to the existing product, we're working on a VPN next (primarily, as an anti-censorship tool); and plan to start working on a cloud-based browser.
