6+ hires across North America and the UK, the first within two weeks of engagement, with 96% retention. The partnership is exclusive, with mandates ongoing.

What truly sets GS Group apart is their ability to source candidates who weren’t easily available in the general recruiting process, and they help find candidates for even the most niche and specialised roles. Our team is stronger than ever because of the talent GS Group has helped us bring on board.
