The four fighting it out have already beaten more than 55 rivals from across the UK in a two-day live pitching extravaganza, held recently in Liverpool. Entrepreneurs had to sell their vision and excel in a quizzing from CrowdMission.com founder Karen Darby, Crunch CEO Darren Fell, David Malone, Northern Ireland telesales manager at hibu and ICAEW's Charles Carter.
So who are the four semi-finalists battling it out on 16 November?
England: Jim Shaikh (above, right), founder of Yoomi, an innovative self-warming baby bottle which heats up in 60 seconds.
Scotland: Sam Zawadski, founder of AdvancetoGO, a website that helps landlords manage property which Sir Richard Branson described as a service that "will challenge the property industry".
Wales: Alba McConnell (above, left), founder of Rio - A Taste of Brazil, a range of sauces with authentic Brazilian flavours.
Northern Ireland: Shauna McCarney (above, centre), founder of Heavenly Tasty Organics, an organic baby food company.
There are also 22 wild card contestants, two of whom get a chance to pitch in the final - a public vote decides which business should go through. We're hoping our two very own Smarta 100 winners included in the wild card selection make it: Living the Dream Performing Arts Company and MarketInvoice. Good luck guys!
