Captify’s technology provides adverts to web users based on their search history. Analysing over a billion searches a month, the company uses the data to run campaigns for the likes of BMW, Samsung and Dyson. Since opening their doors in 2011, founders Dominic Joseph, 31, and Adam Ludwin, 28, have seen sales grow to £6.3m. They have opened offices in Kiev and Hamburg, and have ambitions to expand further in Europe. Panoramic Growth Equity invested £1.2m in 2013 for a minority stake, and in June this year Captify raised £8m in a funding round led by Smedvig Capital.
