Half-year figures were not disclosed, but the quoted growth rate is more than twice that of last year’s first-half performance, when revenue was up 22%.

It also shows an improvement on the agency’s full-year 2009 results, which reported sales up 27% to £11.8m.

“The board expects the company to deliver further good progress in the second half,” said the trading update. “We plan to deliver strong revenue growth, while continuing to invest heavily in our strategically important ‘Juicy’ product development and talent, to support our longer term ambitions to become a top 10 global market research group.”

‘Juicy’ products accounted for 61% of group revenue in 2009, up 66% year-on-year, and the aim is to push it to 70% this year.

BrainJuicer is also looking to grow internationally, and in the first six months of the year opened new offices in Brazil and China. It also announced today the appointment of Carola Verschoor, the former international marketing director for coffee innovations at Sara Lee, as managing director in Holland.
