Promethean logoThey might have floated on the London Stock Exchange in the middle of a recession but Promethean reported revenues up by 35 per cent and operating profit up by 42 per cent when it delivered its first set of half-year results to the city this week.

Jean-Yves Charlier, CEO of the Blackburn-based company, a leader in interactive whiteboard and whole-class technologies, said: “More than 90 per cent of our sales are now outside the UK, with North America continuing to be our lead market, accounting for some two-thirds of our sales and showing 33 per cent growth in the period.
