Wengel (pictured) was the chief executive of GutCheck for three years until 2023, when he joined Woxi as president, overseeing the company’s commercial launch. His career in research, analytics  and innovation has included senior leadership roles at Kantar, Nielsen and Procter & Gamble.

At Radius, he takes over from managing director Chip Lister, who will remain on the board of directors and will advise the company on strategic initiatives.

Wengel’s appointment builds on the acquisitions Radius has made in the past 18 months, buying Strive Insight (now Radius EMEA) and 7^th Sense in 2024, followed by Illuminas North America earlier this year.

Wengel will guide the firm’s continued expansion, integrate the recently acquired businesses and strengthen the focus on outcomes-based research that aligns with client priorities.

Lister said: "Rob was carefully selected for his demonstrated leadership and ability to create new opportunities for the organisations we serve.

"He brings a sharp insights perspective and a clear vision for how our work can evolve in step with the dynamic needs of our clients."

Wengel added: "The team’s focus on delivering strategic, insight-driven value to clients resonates deeply with my own philosophy. I look forward to building on the company’s strong foundation to drive continued innovation and impact."
