Huh. I visited your site and reading the tag line "a fast, secure and scalable websocket & tcp server", I assumed it was just a socket server and had no idea it was actually a data-store.
You really need to make the explanation clearer ^^
Your animation "built for a new generation of apps" is awesome but it doesn't not show clearly what role deepstream plays in it.
I don't think it is possible to explain everything clearly in one sentence so I wouldn't start with a tagline like that.
