A few years ago I worked in a startup, and to find customers we needed to find web sites using certain technologies (e.g. wordpress and certain plugins). We used the service of an extremely similar SaaS startup for a little bit -- that basically did the exact same thing as Mixnode. That startup didn't work out and was shut down soon (and my startup didn't work out either). Wish you best of luck and hope things work out for you, maybe the tech climate and trends have evolved since a few years ago and this could work out a business now.
