Alexander Fortmüller is a corporate director and investment executive closely associated with SoftBank’s ecosystem and with BALYO, the French listed robotics company. According to BALYO’s board-candidate information sheet, he has served on BALYO’s board of directors since 2023 while also acting as Director of Development and Investments at SoftBank Group International. The same document shows that he holds several mandates across international technology companies, highlighting a career built around venture-style investing, strategic participation oversight, and governance of high-growth businesses. His recent background is strongly connected to technology, automation, and digital infrastructure. BALYO states that he has served as a director of Berkshire Grey, Skylo Technologies, InMobi Pte. Ltd., Oyo Mountainia UK Limited, and Cornami, Inc. Over the last five years, he has also held multiple other responsibilities in the sector. These included board roles at Inc. LDH Growth Corp I, IoT Pelion (Israel), Pelion (Finland) OY — where he also chaired the board — and ULSee Cayman Co., Ltd. In addition, he acted as a censeur for Airspan Networks and Unicommerce eSolutions Private Limited, and served as an advisory board member of Goggo Network GmbH. At BALYO, Fortmüller’s role became particularly visible after SoftBank increased its stake and became the controlling shareholder. Regulatory and company disclosures identify Silver Bands 4 (US) Corp., a Delaware corporation linked to Fortmüller, as the vehicle used by SoftBank for the public tender offer followed by a squeeze-out process. BALYO’s communications also note that he did not participate in deliberations or voting on board decisions involving agreements between BALYO and that related entity. Overall, his profile combines international investment expertise, board experience in technology businesses, and exposure to complex governance and capital-structure matters in listed-company settings.
