Deep See Research is a research firm specializes in international consumer research including consumer research, advertising research, brand research, mystery shopping, social media research and marketing research. They have an established global network of offices, with researchers in just about every language.
This firm seems to specialize is online research from social media, to websites, to branding, etc. This is something I think that sets this firm apart from others. A lot of marketing and advertising messages are going online, so a firm that specializes will be very useful in the coming years.
