Specialist technology investor Par Equity has led a consortium that has invested £800k in Publisher Discovery, a provider of services for online advertisers.

Publisher Discovery supports the growing performance or “affiliate” marketing space by helping companies that advertise online target potential customers more accurately. It uses AI technology to monitor millions of websites, ranking them by relevance and traffic to increase efficiency for advertisers and reduce frustration for browsers. Publisher Discovery holds two patents for its AI technology and is currently applying for a third.
