The Sharp Edge think we're "rising stars". And our friends Fuzzy's Grub sandwich shops too. So this is stardom...

HARRY BRIGGS AND MARCUS WALEY-COHEN

Some of the best business partnerships start at school. Harry Briggs and Marcus Waley-Cohen are a couple of old Etonians who passed on the opportunity of running the country to flog health drinks instead. Their Firefly health drinks are building up a real following. They started off with three varieties - Wake up, Detox and Chill Out. And now the business partners have just launched a limited edition Valentine's Day drink. Briggs, 27, says: "We sat down and analysed our business and thought about where we wanted to be in the future."

The drinks are completely natural and the ingredients were devised working with experienced herbalists. They are sold in cafés predominantly in London and the South East, as well as in Waitrose, Harrods and Selfridges. International sales are also driving the business in Denmark, Dubai and the US. The pair have almost trebled monthly turnover in the last year from £25,000 to £70,000.
