iD Factor said it had relocated to Holborn in London from Richmond in Surrey as part of its expansion.
Jon Gumbrell, managing director at The iD Factor, said: "This is the right time to expand: we're profitable and the online research industry is booming. Our investment in personnel, building our panels and in an extensive marketing campaign puts us in a great position to capitalise on that boom."
The company was bought by direct marketing firm TheMutual.net for 拢2.86m in January this year.
The iD Factor provides market research and analysis for online fieldwork studies.
