Swiss running company On hires new CFO

On Wednesday, Zurich, Switzerland-based footwear maker On announced Frank Sluis as its new CFO, effective May 1. Sluis will replace Martin Hoffmann, who took on the dual role of CEO and CFO last year.

In a press release, Sluis said On’s “ambitious global growth trajectory” is an aspect of the brand he feels is “truly unique.”

“I am deeply passionate about sports and sustainability, and I strongly believe in On’s mission and culture. I could not be more excited to join the team and contribute to On’s journey forward,” he said.

On is known for its performance running shoes with square-shaped holes on the midsole. Within the last few years, the brand has risen to prominence alongside others like Hoka and Brooks.

In Q3 2025, parent company On Holding reported almost 25% YoY sales growth and nearly 50% growth in adjusted EBITDA, though US sales fell short of expectations.

Hoffmann, who is staying as CEO and joined On as CFO in 2013, said that Sluis “complements our management team with experience at a scale significantly larger than where we are today, yet fully aligns with our values.”

Most recently, Sluis was CFO of Europe and Indonesia at Ahold Delhaize, the global food retail group. In his 25-year career, he has also held financial leadership positions at multinational consumer businesses Reckitt Benckiser and Unilever.
