Born in 1975 in Poland, Octave Klaba is the founder of OVHcloud, a global cloud player and the leading European cloud provider. A graduate of ICAM Lille, he founded OVH in 1999 in the north of France, with the ambition to build an internet infrastructure that is both high-performing and accessible. From the very beginning, he defended a vision of an open internet, based on the freedom of choice for customers. Under his leadership, OVH experienced rapid growth, first in France and then internationally. The company stands out for its technical innovations, notably in energy management of data centers and the development of server ranges. In 2016, initiating a shift towards the cloud, Octave Klaba used KKR and TowerBrook investment funds to accelerate the group's expansion into new markets. In 2020, under his leadership, OVH became OVHcloud in order to assert its positioning on a fast-growing cloud market - public and private. Between 2018 and 2025, he served as Chairman of the Board of Directors and also chaired the Group's Strategic and CSR Committee. He is closely involved in the company's strategic development, in line with its long-term vision. In October 2025, he was appointed President and CEO of OVHcloud. Convinced of the need for a European alternative to the American cloud giants, Octave Klaba makes data sovereignty, service transparency, and freedom of choice his priority. He actively supports tech startups, particularly in AI and quantum computing, and promotes the development of an innovative and independent digital ecosystem. Through his engagements in Shadow and Qwant, he is pursuing this same ambition: to help build a strong, independent digital ecosystem, and establish a European digital champion driven by trust, performance, and technological sovereignty.
