Latitude owner Jellyfish has been acquired by Fimalac, the holding company owned by French billionaire Marc Ladreit de Lacharrière.
The French group will merge its data-driven marketing specialist Tradelab into London-based Jellyfish – which established its first presence in the North after acquiring Warrington-headquartered Latitude from TransUnion (formerly Callcredit) in April – as part of the deal.
The agency, which is valued at £500m by the transaction, will increase in size by a third to 1,100 people. Fimalac will own around 74% of the combined entity.
Founded in 2005, Jellyfish works with clients including Uber, eBay, Disney, Spotify, Aviva and Asos. Last year it recorded sales of £53.7m and profits of £8.5m.
