Between 1982 and 1983, Horlick worked for her father in the family business. She joined
S. G. Warburg & Co. as a graduate trainee in 1983, starting in the investment management business, which later became
Mercury Asset Management. She was appointed a director in 1989. She joined
Morgan Grenfell Asset Management in 1991 and was appointed Managing Director of the UK investment business in 1992. During five years that she was in charge, the amount of assets managed by the firm grew from £4 billion to £18 billion. She was suspended from the job on 14 January 1997 and resigned two days later, after it was claimed she was moving to a rival and trying to get colleagues to join her. Accompanied by a large contingent of reporters, Horlick flew to the company's headquarters in
Frankfurt to demand that her job be reinstated. As her future husband later described it, "Amid rumours that she was going to defect to a rival, Horlick had been suspended from a senior job ... She took the trip to Germany accompanied by a piranha shoal of story-hungry hacks." She set up SG Asset Management in 1997 and
Bramdean Asset Management LLP in 2005. In 2008 one of Bramdean's funds, Bramdean Alternatives, had £10 million, about 10 per cent of its assets, invested with
Bernie Madoff, money Horlick said she was uncertain she would ever see again. At the time Bramdean shares lost one third of their value. Horlick lost control of Bramdean Alternatives on 19 November 2009. She founded and is the CEO of Money&Co., a marketplace lending business focusing on business loans. She also has a film business called Derby Street Films. Horlick is the Chairman of film finance fund Glentham Capital, which raised funds on
equity crowdfunding platform
Seedrs in 2013. She was also a founding partner of Rockpool in 2011, which has its offices in
Victoria, London. The other businesses are based in nearby
Mayfair. ==Politics==
