William Hill’s chief marketing officer Kristof Fahy is leaving the bookmaker after five years.
He is set to depart in April and does not yet have a job to go.
A spokesman said there was no “further information” on his potential replacement.
During his tenure, Fahy steered the company’s charge into the digital space, instilling a greater focus on personalisation and mobile.
He leaves with marketing at a high at William Hill, having masterminded a £130m strategy this year to boost revenues amid greater competition from online bookmakers. The gamble paid off, with increased marketing around the World Cup having a knock on effect in its latest quarter when revenue rose 23 per cent year-on-year.
Fahy joined the business in 2010 from Yahoo! where he was VP of marketing. Prior to that he was brand director for Blackberry.
