Browser Code Origin Info Requested

I'm curious about the origins of this new browser code. Is it a grounds-up effort by Piriform? Does it use any open-source code? Chromium based, maybe? I'm really hesitant to use it until I know a bit more about it, without the marketing jargon.

It is Chromium based.
