Enterprising twins and UCL alumnae Joyce and Raissa de Haas have secured £4.5 million to help their premium mixers business expand further into the UK and international markets. Double Dutch is a global, award-winning premium mixers brand co-founded by the Netherlands-born twin sisters, who both studied UCL MSc in Technology Entrepreneurship 2014. The sisters' interest and passion in quality drinks mixers was first developed at home, where their parents ran tasting events with different spirits.
