McKee (pictured) will focus on the day-to-day running of the business, having previously been a director at the company and having joined the firm in 1999.

McKee replaces founders Ann Morgan and Sue Van Meeteren, who will re-focus on key accounts and improving collaboration between Jigsaw and other business units across the Strat7 Group.

In her new role, McKee will focus on developing existing accounts and growing the business with new clients and an expanded presence in the US, reporting to Strat7 Group chief executive Barrie Brien.

At a Strat7 Group level, McKee is co-lead on one of Strat7’s biggest cross-disciplinary accounts and will explore further collaborative opportunities across existing accounts and within new business, as well as working closely with Strat7.ai, the group-wide, cross-disciplinary team focused on integrating AI tools across the business.

Van Meeteren said: “Sarah embodies all the characteristics that have made Jigsaw the successful business it is today.

“Alongside the brilliant relationships she’s established with clients, she has huge credibility within Jigsaw and across Strat7 Group more broadly. We really couldn’t ask for a better MD.”

Morgan added: “Sarah was the first to join us 25 years ago. She put her trust in us when the business was in its infancy, so this is an incredibly satisfying, full circle moment.

“We couldn’t be happier to place our trust back in Sarah to carry the business forward and she is already doing a terrific job.”
