The acquisition, for an undisclosed amount, will increase TestSet’s healthcare expert network and support its work across the UK.

The company, which is part of Ackwest Group, said it would maintain recruitment and participant engagement standards for the panel following the acquisition.

TestSet introduced a healthcare division called TestSet Health to Europe and the UK last year, having launched its European business in London in 2024.

Colin Turner-Kerr, managing director at TestSet UK & EU, said: “Bringing the Shift Insight panel into our network isn’t just about scale. It’s about investing in products and services our clients need.”

Michael Sanfelippo, president at TestSet, added: “With this acquisition, our customers gain broader global reach and faster access to the specialised healthcare data that helps them make accurate, faster decisions. It continues to reflect our investment in first-party data to deliver quality results.”
