This term was coined by Professor Thomas Hellmann of the Saïd Business School at Oxford University during the mentoring of technology startups through the Creative Destruction Lab program. It refers to one of the CDL mentors, Neil Wainwright, who developed a skill and process for assessing the home page of any technology startup's website and for recommending changes, through a thorough review of the headline, subheadline and call to action on the website. In effect, Wainwrighting a website.
This website needs some Wainwrighting.
