William Mortimer Muirhead AO was born in 1946 in Adelaide, South Australia. He is a senior advertising executive. Wikipedia lists him as a former Chief Executive and President of Saatchi & Saatchi Worldwide, when he was based in New York. PitchBook says he was one of the first account handlers at Saatchi & Saatchi in 1971 and later became chairman of Saatchi & Saatchi Europe.
He co-founded M&C Saatchi and served as an executive director there. Wikipedia says he worked on British Airways campaigns for about two decades and on several Conservative Party campaigns. In 1985 he co-founded the Famous Porkinson Banger Company, a food brand, with Norman Parkinson and Paul Arden.
Outside advertising, he was Agent General for South Australia in London from March 2007 to July 2020. He was made an Officer of the Order of Australia in 2023. In 2011 he founded the South Australia Club, an international community.
PitchBook classifies Muirhead as an individual angel investor and records four investments, in two companies. Three are in Second Home, a London alternative office space company, dated April 2014, January 2016 and December 2019. PitchBook labels the first two Early Stage VC rounds. Wikipedia says he and his M&C Saatchi partners are key investors in Second Home.
The most recent recorded deal is a seed round in Supernova on 18 October 2022. PitchBook files Supernova under social and platform software. Deal sizes are not disclosed. This record comes from a single database profile and may be incomplete.
The public record is too thin to state a thesis. The recorded deals are in property and workspace (Second Home) and social or platform software (Supernova). Both companies are listed as generating revenue at the time of investment. The one deal with a disclosed round type is a seed round. His base is London. We found no public statement on check size, preferred stage, or what he looks for in founders.
