Octavius Orlando Irvine Casati Black (born 2 May 1968) is a British businessman best known for founding the company The Mind Gym.
Black is the son of advertising executive Brinsley Black (1930-2011), a socialite, named as one of the best-dressed Englishmen in the inaugural issue of Men in Vogue in 1965, and his second wife, Lady Moorea Wyatt (nee Hastings) (1928-2011). She was the daughter of the Labour peer and academic Francis Hastings (1901–1990), and Cristina Casati Stampa di Soncino (1901–1953), the only child of Camillo, Marquis Casati Stampa di Soncino (1877-1946) and Italian heiress and eccentric patroness of the arts Luisa Casati (1881–1957). Much of the family's background is explained in the 2014 biography The Red Earl: The Extraordinary Life of the 16th Earl of Huntingdon by Lady Selina Shirley Hastings, the earl's daughter and the aunt of Octavius Black.
Through his mother's earlier marriage to politician and diarist Woodrow Wyatt, Black has one older half-brother, Pericles Plantagenet Wyatt (born 1963). Through his father, Black has a half-sister, Eliza-Jane.
Black was educated at Eton College at the same time as David Cameron; the two have stayed close, socialising together with their wives. Black studied Philosophy, Politics and Economics at Oxford University.
Upon graduating from university, he joined Booz Allen Hamilton as a business analyst, where he worked predominantly in the Financial Services practice.
Black was brought into AGB Research by Mark Booth to help turn around the market research business, owned by Robert Maxwell. After the disappearance of Maxwell the business went into administration.
Black joined Smythe, Dorward Lambert as their sixth employee. Black became the Sales and Marketing Director of the leading employee communication consultancy of its time with 100 employees and a turnover of £10 million. The consultancy was sold to Omnicom in 1996.
Black is also on the Advisory Board of Teaching Leaders.
Between 2012 and 2014, he wrote an occasional column in the business section of The Sunday Telegraph on the human aspects of business.
The Mind Gym
Black, along with co-founder Sebastian Bailey, started The Mind Gym at his kitchen table in 2000. The privately owned company designs and delivers corporate learning and development programmes. It is most well known for its 90-minute-long training sessions known collectively as “Workouts". The company serves 53% of S&P100 and 61% of FTSE100 companies via 400 qualified Mind Gym Coaches delivering in 40 countries. It operates from three offices (New York, London, Singapore).
In February 2018 the Mind Gym was listed in the Top 20 Leadership Training Companies by the Training Industry.
In April 2018 the Mind Gym was listed at No. 36 on the list of the Top 100 private companies with the fastest growing profits by The Sunday Times.
In 2014, 2015, 2016 and 2017 the Mind Gym featured in the Watchlist of the Top 20 Leadership Training Companies Watchlist according to the Training Industry.
With co-founder Sebastian Bailey, Black co-authored three books (The Mind Gym: Wake Your Mind Up, The Mind Gym: Give Me Time, The Mind Gym: Relationships).
Black's Parent Gym, is a six-week parenting programme for parents of children aged 2–11. It is funded by Black’s commercial enterprise, Mind Gym and applies its corporate training knowledge to help teach parenting skills.
It was piloted in 2010 and now[when?] runs 150 programmes every year for parents in areas of multiple deprivation in London and Brighton and Black hopes to roll it out nationwide. London Mayor, Boris Johnson described it as “Just about the most hopeful thing I have seen.” 
Black married Joanne Cash, a libel barrister, in December 2007. Friends who attended their exchange of vows "included Ed Vaizey and Michael Gove, [...] Viscount and Viscountess Rothermere, Stuart Rose and Kirstie Allsopp." The Telegraph called Cash a "rising star" of the Conservative Party when she stood for Westminster North in the 2010 general election. When she failed to secure the seat, she accused the media of lying about her and her husband.
