The London-based I Spy develops online marketing techniques for clients such as Virgin Media and Vauxhall. Founded in 2005 by Chris Whitelaw, a former investment banker, the company offers a range of services that include search engine optimisation and targeted advertising on social media such as Facebook. With its home-grown software, Upcast, the firm can track consumer responses to online advertising and so help clients to refine their pitch.
