Btwentyfour, the Swiss provider of supply chain data automation software backed by Nordic investor Adelis Equity Partners, has appointed Markus Klahn as its new CEO, effective Sept. 1, 2025. The leadership transition is part of a planned succession to support the company’s next phase of international expansion.
Klahn joins the company after stepping down as CEO of Intershop Communications AG, a publicly listed e-commerce software provider based in Germany. He had served on Intershop’s management board since 2018, initially as COO and, from 2021 onward, as CEO. At Btwentyfour, Klahn succeeds founder Ulf Hallman, who led the company for 25 years and will now shift to a strategic role on the Board of Directors while continuing to support sales and go-to-market efforts.
Founded in 2000, Btwentyfour offers a cloud-based platform that automates the exchange of mission-critical data between brands and retailers. The company serves more than 2,000 product brands and over 40,000 retailers worldwide. Its primary operations are in Sweden, with headquarters in Zug, Switzerland, and a sales office in Germany.
“I look forward to accelerating growth and building an undisputed market leader in automated business transactions,” commented Klahn. Chairman Fredrik vom Hofe said the board was confident in Klahn’s ability to scale the business globally, citing his track record of profitable SaaS growth.
