Poptop – the Newcastle-based events booking platform – has raised a further £440,000 to pursue its global expansion plans. The funding comes from existing investors DSW Ventures and NorthStar Ventures, which was investing from the North East Innovation Fund supported by the European Regional Development Fund.  Poptop’s platform was the first private events marketplace of its type and has revolutionised the way consumers plan and book events from birthdays to grand weddings.
