The London-based firm, which uses technology to recruit research participants using behavioural data, will open the Chicago office in September this year.

Erica Siebert, who joined the company last year after moving from Chicago, will move back to the city to lead the US account management team.

Last month, Liveminds also launched an office in Manila, the Philippines, with two new hires in recruitment and development.  

In London, Lizzie Cree has been promoted to the newly created role of head of operations, Henry Dann becomes account team leader and George Silk has been appointed as account executive. The company has also added three new team members to its behavioural recruitment team.
