Alexander Nix

Both in the UK and the US campaigns, Cambridge Analytica used private information from over 87 million Facebook users harvested from their profiles without permission. In March 2018, Nix was suspended from Cambridge Analytica after undercover video footage showed him claiming his company was using honey traps, bribery stings, and prostitutes, among other tactics, to influence more than 200 elections globally for his clients.

However, according to Wigmore, the work for Leave.EU was done pro bono, without any money changing hand: “Because Nigel [Farage] is a good friend of the Mercers. And Robert Mercer introduced them to us. He said, ‘Here’s this company we think may be useful to you.’ What they were trying to do in the US and what we were trying to do had massive parallels. We shared a lot of information. Why wouldn’t you?” Behind Trump’s campaign and Cambridge Analytica, he said, were “the same people. It’s the same family.”

In February 2018, Nix told the British parliament's Digital, Culture, Media and Sport Committee that his company had not received data from Facebook; following further media reports the committee's chairman, Damian Collins, said "We will be contacting Alexander Nix next week asking him to explain his comments." Nix denies deliberately misleading the parliamentary Select Committee.

In March 2018, The Observer reported that Nix talked "unguardedly about the company's practices" when he was secretly filmed by Channel 4 News reporters posing as prospective clients and that Cambridge Analytica was trying to stop the broadcast of the resulting programme. Nix offered "beautiful Ukrainian girls" to discredit political opponents in Sri Lanka. The secret filming was screened on 19 March as part of a 30-minute segment, with a follow-up scheduled for the next day, focusing on its involvement in the Trump campaign. The conversation appears to portray Nix including entrapment and bribery as potential Cambridge Analytica services.

On 20 March 2018, Nix was suspended from Cambridge Analytica.

On 11 April 2018, The Wall Street Journal published an article about the CEO position at Cambridge Analytica, saying Nix "has officially resigned from his position, according to a person close to the company", but also that a "company spokesman ... denied that Mr. Nix had submitted his resignation".

On 2 May 2018, Cambridge Analytica announced they were "closing and starting insolvency proceedings".

On 8 October 2018, the Guardian reported that Nix referred to Mia Mottley, the elected Prime Minister of Barbados and other government figures via the racial slur of "Niggers" in email communications.

On 23 January 2018, Nix was appointed director of Emerdata Ltd., a new company incorporated in August 2017, along with SCL chairman Julian Wheatland and Cambridge Analytica chief data officer Alexander Tayler. On 16 March 2018, Rebekah and Jennifer Mercer were also appointed directors, members of the Mercer family which backed Cambridge Analytica financially (by at least $15 million, according to the New York Times). Another director of Emerdata is Chinese businessman Johnson Chun Shun Ko [zh] , deputy chairman and executive director of Frontier Services Group, a private security firm which mostly operates in Africa and is chaired by US businessman and strong Trump supporter Erik Prince, who is best known for founding private military group Blackwater USA and being the brother of US education secretary Betsy DeVos. On 13 April 2018, Nix's role of director was terminated.

Before the 2016 United Kingdom European Union membership referendum, Nix's firm was involved in supporting Leave.EU with its Brexit campaign, according to both Arron Banks of Leave.EU, former Cambridge Analytica employee Christopher Wylie, Cambridge Analytica's business development director Brittany Kaiser, and Leave.EU's communications director Andy Wigmore.

Nix attended Eton and studied art history; he is married to shipping heiress Olympia Paus. He started his career as a financial analyst with Baring Securities in Mexico before moving to the strategic communication industry and joining SCL Group. In 2013 he set up Cambridge Analytica, where he became CEO.

In 2013, Nix set up Cambridge Analytica as an offshoot of the SCL Group, to target voters in "more than 40 political campaigns in the US, Caribbean, South America, Europe, Africa and Asia". The company ran Uhuru Kenyatta's presidential campaign in Kenya. In the United States, it was involved in the 2014 midterm elections and the 2016 presidential primaries and election, during which it received funding from the Mercer family. Nix's firm supported both the Ted Cruz and Donald Trump campaigns for the US presidency by using "psychographic" profiles of voters built on data harvested from Facebook.

In 2010 Nix married Olympia Paus (Caroline Victoria Olympia Paus), a Norwegian shipping heiress who belongs to a billionaire family. His wife was born in Athens in 1976 and moved to London in 1979. Norwegian newspaper Dagbladet noted that Olympia Paus belongs to one of Norway's most prominent families, and both her parents independently have large fortunes. On her father's side she belongs to the Paus family (pronounced [ˈpæʉs] ) of steel industrialists and ship-owners; her mother Cecilie Paus (née Wilhelmsen) belongs to the billionaire Wilhelmsen family and has been one of the main owners of Wilh. Wilhelmsen, one of the world's largest shipping companies, since 1978. Olympia Paus is a granddaughter of Norway's largest shipping magnate Tom Wilhelmsen, who was also the honorary consul-general in Norway for Apartheid-era South Africa.

Alexander Nix grew up in Notting Hill, in West London, attended fee-paying Eton College, and studied art history at the University of Manchester. He started his career as a financial analyst with Baring Securities in Mexico for Robert Fraser & Partners LLP, a tax and corporate finance firm. In 2003, Nix left finance to join the to the strategic communication industry with SCL Group.

Alexander James Ashburner Nix (born 1 May 1975) is a British businessman, the former CEO of Cambridge Analytica and a former director of the Strategic Communication Laboratories (SCL) Group, a behavioural research and strategic communications consultancy, leading its elections division (SCL Elections). Cambridge Analytica helped Leave.EU with its Brexit campaign, according to both Leave.EU and Cambridge Analytica staff. The company was also engaged by the Ted Cruz and Donald Trump campaigns during the 2016 US presidential election. The company also ran Kenyan President Uhuru Kenyattas campaign.

Alexander James Ashburner Nix was born on 1 May 1975 to a banking family that belonged to the English landed gentry. His father Paul David Ashburner Nix (1944–2007) was an investment manager who spent twenty-seven years with the M&G Group before joining Consulta in 1995, and was a shareholder of SCL Group.

Olympia Paus has never lived in Norway as her parents left the country in 1972 for Athens and London, where her father Christopher Paus worked in the shipping industry and as an investor; he has been reported to own shares worth close to 100 million British pounds in companies in the offshore petroleum industry. In 2012 Nix and Olympia Paus purchased a home in Notting Hill for around 5 million pounds. They have three children.

The Ashburner Nix family were wealthy bankers for several generations and had long-standing ties to India dating back to the East India Company's rule from the mid 18th century; family members were prominent merchants and administrators in British-ruled India. His family owned Tilgate House, a large manor and 2,185-acre estate in the Crawley area. It was purchased by the wealthy Indian-born businessman George Ashburner in 1862 and inherited by his daughter Sarah (born 1845 in Calcutta), who in 1865 married banker John Hennings Nix, one of the partners in the London private bank Fuller, Banbury, Nix & Co. His great-grandfather Charles George Ashburner Nix sold Tilgate House in 1939. Alexander Nix is also descended from liberal politician James Clifton Brown and from the banker and politician Sir William Brown.
